P421 INTRA–CARDIAC AND ALL LAYERS CARDIAC INVOLVEMENT BY SQUAMOUS NON–SMALL CELL LUNG CANCER

Abstract A 73 year–old man was referred by his general practitioner to our ambulatory for worsening dyspnea. He also reported substantial weight loss (almost 20 kg during the last three months), new onset dysphonia and dry cough. The patient’s medical history also included a former tobacco addiction, arterial hypertension and dyslipidemia. There was not history of cardiomiopathy. Electrocardiogram, showed: sinus rhythm, 60/min with inferior and anterior–lateral abnormality of repolarization. No laboratory exams were available at the first visit. An echocardiogram was performed, showing: marked septal hypertrophy (IVSd= 23 mm), septal hypokinesia, with an ejection fraction at lower limits of normality (EF= 54%), neither systolic anterior motion of the mitral valve. Minimal pericardial effusion was seen. We required a CT scan of the chest, that showed a large (5x8x11cm) mass in the left upper lobe with ipsilateral mediastinal lymphadenopathy. The mass directly extended into the mediastinum with infiltration of pericardial leaflet, left atrium and the left wall of the aortic arch. A hypodense formation of approximately 4 cm in the interventricular septum in the apical portion was reported. PET–CT with FDG was performed, which documented hypercaptation of the radioactive tracer at the level of the above–mentioned lesions. The patient underwent fine–needle aspiration biopsy of the lung mass and the histological examination led to the diagnosis of squamous cell carcinoma of the lung. Systemic treatment with carboplatin plus placlitaxel and pembrolizumab was subsequently started. A cardiac CMR was performed, which documented an area of 30x17x31 mm located at the septal (mid–apical portion), apex and parapical portion of the free wall of the right ventricle with transmural extension. At this area, extensive late gadolinium enanchement (LGE) at marginal level with a central non–capillary core and hyperintense in T2 sequences (compatible with central necrotic lesion). The pericardium also showed LGE and a mild pericardial effusion (maximum 8 mm); left atrium involvement, seen on CT, was not documented . After he completed the third cycle of CHT, at 5 months from the diagnosis, the echocardiogram showed a substantial disappearance of the mass infiltrating the interventricular septum without evidence of pericardial effusion. The ecg was substantially unchanged. The patient stopped carboplatin and paclitaxel after 3 cycles and kept maintenance pembrolizumab still ongoing.

Too Much Too Soon? The Catch-22 of Catching COVID-19

IntroductionMyocarditis has become a well-recognised cardiac complication of SARS-CoV-2 infection. Now, there are growing reports of rare incidences of myocarditis following receipt of mRNA COVID-19 vaccines.Case ReportA previously healthy 35-year-old male tested positive for COVID-19 on 8/12/21. He never required hospitalisation and was thought to have cleared the infection by 9/5/21. Three weeks later he received the first dose of Pfizer-BioNTech BNTT162b2/Comirnaty mRNA COVID-19 vaccine. Five days later he presented to emergency with chest pain alongside myalgia, headache and cough. His troponin-T was below reference range (RR), electrocardiogram showed sinus rhythm with mild, diffuse T-wave flattening, and no evidence of pericardial effusion was seen on bedside transthoracic echocardiogram (TTE) so was discharged. Two days later he represented to hospital with fevers, vomiting, diarrhea and a maculopapular rash. His subsequent admission was complicated by rapid deterioration and his management reflected a diagnostic dilemma with wide differentials. On day 2 of admission he became haemodynamically unstable requiring vasopressor therapy with a high sensitivity (hs) troponin-I of 103ng/L (RR <26ng/L). On day 4 he developed atrial fibrillation, worsening respiratory distress, peak hs troponin-I of 1474ng/L and required intubation, direct-current cardioversion and venoarterial extracorporeal membrane oxygenation (ECMO) for intractable heart failure. TTE here showed severe global systolic impairment with a left ventricular ejection fraction of 15% and small pericardial effusion. His subsequent treatment targeted possible multiorgan sepsis with antibiotics, vaccine-induced myocarditis with immunosuppressive therapy including anakinra and parental corticosteroids, or delayed COVID-19 myocarditis with supportive care. He was later extubated and successfully decannulated from 5 days on ECMO on day 11. Cardiac magnetic resonance imaging on day 12 showed elevated T1 and T2 values consistent with ongoing myocardial edema, but normal ventricular volume, thickness and function.SummaryThis is a case of fulminant myocarditis whereby the aetiology is unclear considering recent COVID-19 infection and mRNA vaccination. This raises questions as to the ideal timing of vaccine, type of vaccine and requirement for cardiac screening prior to vaccination in patients who have recovered from COVID-19.

Cardiovascular Manifestations of Systemic Lupus Erythematosus: An Overview

Systemic Lupus Erythematosus(SLE) is a multisystem autoimmune disease with variable presentations. A proposed mechanism for the etiology of SLE involves the development of autoantibodies that result from a defect in apoptosis. The specific defect involves the “find-me” (adenosine triphosphate [ATP]/uridine triphosphate [UTP]) or “eat-me” (phosphatidylserine) signals activated upon release of red cell nuclei. In the absence of apoptosis, the nuclei break down, causing inflammation and contributing to the development of autoimmunity. Many signs and symptoms of SLE are caused by either circulating immune complexes or direct effects of antibodies on cells. A genetic predisposition for SLE exists, and the concordance rate in monozygotic twins is between 25% and 70%. If a mother has SLE, her daughter’s risk of developing the disease is 1:40, and her son’s risk is 1:250. The course of SLE consists of intermittent remissions punctuated by disease flares, and organ damage often progresses over time. Pericarditis is the most frequent cardiac manifestation; it can be documented by ECG, auscultation of a friction rub, or evidence of pericardial effusion. It usually responds to anti-inflammatory therapy and infrequently leads to tamponade. More serious cardiac manifestations are myocarditis and fibrinous endocarditis of Libman-Sacks. The endocardial involvement can lead to valvular insufficiencies, most commonly of the mitral or aortic valves, or embolic events. It has not been proven that glucocorticoid or other immunosuppressive therapies improve lupus myocarditis or endocarditis. Still, it is usual practice to administer a trial of high-dose steroids and appropriate supportive treatment for heart failure, arrhythmia, or embolic events. As discussed above, patients with SLE are at increased risk for myocardial infarction, usually due to accelerated atherosclerosis, which probably results from immune attack, chronic inflammation, and chronic oxidative damage to arteries.

Neoplasia-Associated Pericarditis—Predictor of Cancer Progression?

Pericarditis may signal the presence of cancer, even in the absence of other clinical or paraclinical signs. Corollary, the following question arises: Could the discovery of a newly developed pericarditis be used in patients with known neoplasia as a marker of cancer progression? In an attempt to find an answer to this question, this two-centre study included 341 consecutive patients with a confirmed diagnosis of cancer and evidence of pericardial effusion at echocardiography and/or CT/MRI scan. The patients’ data were collected retrospectively if they further fulfilled the following inclusion criteria: available medical data from confirmation of pericarditis until evidence of cancer progression or until at least 12 months without progression. The average age of the patients was 62.16 years (22–86 years), and the study comprised 44.28% males and 55.71% females. All types of the most common neoplasms were represented. The results showed that 85.33% of patients had cancer progression temporally linked to pericarditis. Of these, 41.64% had cancer progression within 18 months after the diagnosis of pericarditis with a median time to progression of 5.03 months, ranging from 0 to 17 months; 43.69% had progression within a maximum of 2 months before the diagnosis of pericarditis. Only 14.66% had no cancer progression during the observation period. We concluded that pericarditis could be a sensitive marker of cancer evolution that could be widely used as a follow-up investigation for cancer patients as a marker of progression or recidive.

Abstract 16918: COVID-19 Associated Acute Myocardial Injury With Prolonged Troponin Elevation

Introduction: Acute myocardial injury in the setting of COVID-19 has been well described and is associated with higher mortality. Hypothesis: Myocarditis has been reported as a rare cause of myocardial injury in at least seven recent case reports. Methods: A 70-year-old man with coronary artery disease status post bypass surgery with recent hospitalization for left shoulder septic arthritis with MSSA bacteremia was readmitted 10 days later with a positive PCR test for SARS-CoV-2 at a local nursing facility. His symptoms were dyspnea, chest pain, fever, nausea, and diarrhea. Previous hospitalization he underwent evaluation for chest pain with cardiac catheterization revealing ejection fraction (EF) of 45% and patency of all three grafts. Results: Laboratory investigation showed elevated markers of myocardial injury with high sensitivity troponin I (hs-TnI) of 17,643 ng/L and B-type natriuretic peptide of 2,627 pg/mL, elevated C-Reactive Protein, D-dimer, and sedimentation rate. Chest X-ray showed hazy opacity in the infrahilar right lung. ECG notable for a first degree AV block with no ST-segment elevation. Transthoracic echocardiogram (TTE) showed an EF of 20% with global left ventricular dysfunction with hypokinesis of the right ventricle. No evidence of pericardial effusion. Blood cultures were negative. Management of heart failure led to clinical improvement. Over the next three months, Hs-TnI level stayed elevated at 11,339 ng/L for four weeks and trended down to 6,791 ng/L. The patient was seropositive for COVID-19 IgG eight weeks after the diagnosis of COVID-19 was made. Conclusions: We report the first case of COVID-19 related myocardial injury with prolonged and extreme troponin elevation. Recent favorable cardiac catheterization further supports immune mediated myocarditis over ischemic cardiomyopathy. Unfortunately, no endomyocardial biopsy has been performed.

The patient’s pregnancy was complicated by gestational diabetes. Her surgical history was notable for adenoidectomy, a previous cesarean section, and dilation and curettage following a spontaneous abortion. Maternal medications included prenatal vitamins and glyburide. Family history was noncontributory. This pregnancy was planned and naturally conceived. The woman received appropriate prenatal care. Noninvasive prenatal screening showed her to be at low risk and cell-free fetal DNA screening was negative. She had a normal anatomy scan at 20 weeks’ gestation. Fetal ultrasonography performed at 36 weeks' gestation for evaluation of fetal growth demonstrated a prominent rounded vascular structure in the quadrigeminal cistern with turbulent flow consistent with a VOGM. Fetal echocardiography at that time revealed dilation of the right atrium and right ventricle with normal biventricular function. There was no evidence of hydrops. Imaging at 37 weeks’ gestation in the Boston Children’s Hospital MFCC included repeat comprehensive fetal echocardiography, fetal ultrasonography, and fetal brain magnetic resonance imaging (MRI). Echocardiography revealed a markedly enlarged right atrium and right ventricle with mild right ventricular dysfunction. Moderate tricuspid regurgitation was noted, the innominate vein was markedly dilated, and the superior vena cava had increased flow. The interventricular septum was dyskinetic, suggesting increased pressure within the right ventricle. There was a patent foramen ovale and a patent ductus arteriosus with right-to-left shunting throughout the cardiac cycle. No evidence of pericardial effusion or hydrops fetalis was seen. Fetal ultrasonography showed a singleton male fetus with biometry measurements, including head circumference, corresponding to estimated gestational age. Amniotic fluid volume was normal. The fetal survey demonstrated a large midline intracranial vascular structure in the expected …

P1707 Strain imaging - resolving the diagnostic conundrum of cardiac amyloidosis

Abstract Introduction Cardiac amyloidosis is a common cardiac condition and is still significantly underdiagnosed. Autopsy studies revealed that myocardial tranthyretin amyloid deposition is found in up to 30% of patients with HFpEF (heart failure with preserved ejection fraction). A study in 2015 reported that 13% of patients hospitalised due to HFpEF (older than 60 years old and with left ventricular hypertrophy - LVH) had moderate to severe uptake on the Technetium DPD scintigraphy. Strain imaging through Echocardiography can be a useful diagnostic tool and can provide valuable clues towards the aetiology of LVH. Relative "apical sparing" pattern of longitudinal strain has been reported to have good sensitivity and specificity in differentiating patients with cardiac amyloidosis from controls. Case A 66 year old man presented with progressive breathlessness and peripheral oedema. His past medical history included peripheral neuropathy, bilateral decompression procedures for carpal tunnel syndrome and IgM Monoclonal Gammopathy of Undetermined Significance (MGUS). His B-type natriuretic peptide levels were elevated and his ECG showed normal sinus rhythm, RsR" pattern on the anterior leads and no evidence of LVH. The transthoracic echocardiogram showed moderate concentric LVH, normal left ventricular systolic function and mildly impaired left ventricular diastolic function. No evidence of pericardial effusion. Urine protein:creatinine ratio findings were consistent with nephrotic range proteinuria. He had a cardiac MRI that confirmed normal biventricular wall motion and systolic function and a moderate increase in the wall thickness of both ventricles, but showed no evidence of late gadolinium enhancement. At this point, we repeated his transthoracic echocardiogram with the use of strain imaging and it revealed a pattern of apical sparing suggestive of cardiac amyloidosis. After collaboration with the Haematology team, a bone marrow biopsy was performed that showed that the MGUS had progressed to IgM multiple myeloma. There was however no evidence of amyloid deposits. He was subsequently referred to the national amyloidosis centre (as per family request), where a SAP (serum amyloid P) scan showed renal and splenic amyloid deposits confirming Light-chain Amyloidosis. To exclude the possibility of TTR Amyloidosis, he also had a 99mTc-DPD scintigraphy which did not detect any amyloid deposits. He was treated under the care of the Haematology team with Velcade/Cyclophosphamide/Dexamethasone chemotherapy. Conclusion In patients with a clinical suspicion of cardiac amyloidosis, Echocardiography with strain imaging can be very useful and should be performed routinely. Furthermore, in patients with high clinical suspicion of cardiac amyloidosis, diagnostic investigations should persist even if the initial workup does not yield specific findings.

Bilateral pulmonary agenesis diagnosed in the 13 th week of gestation - a case report and literature review

Bilateral pulmonary agenesis (BPA) is a rare congenital lung malformation incompatible with extra-uterine life, diagnosed by various prenatal imaging modalities in the second and third trimesters. Essentials for diagnosis are complete absence of lungs and bronchi and no pulmonary vascular supply. In the present case, both convex and vaginal ultrasound scan performed at 13th GW revealed an anechoic content in the entire fetal thorax with no evidence of pericardial effusion, fetal heart diseases, or any other accompanying congenital malformations. On three-vessel view (3VV), bifurcation of pulmonary artery could not be identified, which confirmed the diagnosis of BPA. In conclusion, clinical importance of combining the up-to-date technological tools and clinical expertise in establishing the diagnosis as early as in the first trimester allows the clinicians to terminate the pregnancy with the lowest incidence rate of eventual complications related to the procedure. According to the literature data, this is the first and therefore unique case of BPA diagnosed in the 13th week of gestation.

Cardiac A-lines in fast scan as a sign of pneumopericardium

BackgroundTraumatic pneumopericardium is rare and usually results from blunt injury. Diagnosis through clinical and chest X-ray is often difficult. Ultrasound findings of A-line artifacts in the cardiac window may suggest pneumopericardium.Case presentationA young man involved in a car accident and sustained blunt thoracic injuries, among others. As part of primary survey, FAST scan was performed. Subxiphoid view to look for evidence of pericardial effusion showed part of the cardiac image obscured by A-lines. Other cardiac windows showed only A-lines, as well. A suspicion of pneumopericardium was raised and CT scan confirmed the diagnosis.ConclusionsAlthough FAST scan was originally used to look for presence of free fluid, with the knowledge of lung ultrasound for pneumothorax, our findings suggest that FAST scan can also be used to detect pneumopericardium.

Symptomatic pericardial effusion in Hodgkin's lymphoma: a rare occurrence. Case report and review of the literature.

Pericardial effusion is observed in approximately 5% of patients with Hodgkin's lymphoma but is rarely symptomatic. We report a case in which a 21-year-old woman with newly diagnosed Hodgkin's lymphoma was found to have symptoms and radiographic evidence of pericardial effusion. Symptomatic pericardial effusion in patients with Hodgkin's lymphoma is extremely rare, with few reports in the literature. The mechanism for the heart and pericardial involvement is reviewed along with a description of the presenting symptoms and differential diagnosis.

Diagnostics and therapy of pericarditis and pericardial effusion

This article describes the diagnostics, differential diagnostics, multimodal imaging, medicinal and invasive diagnostic therapy of acute and chronic pericarditis, constrictive pericarditis, pericardial effusion and cardiac tamponade under etiological aspects and on the basis of the guidelines of the European Society of Cardiology (ESC). The starting point of the decision tree is the symptomatic patient with echocardiographic evidence of pericardial effusion. The principle feature of the diagnostics is the etiopathogenetic allocation of the pericardial disease which influences the clinical picture, course therapy and prognosis. Infectious pericarditis (e.g. viral, bacterial and tuberculous) is differentiated from sterile autoreactive pericarditis and from neoplastic pericardial effusion by the cytology of the effusion and immunohistological and molecular investigations of the pericardial and epicardial biopsies. Pericardioscopy plays an important role in the recognition of suspicious areas. In many cases intrapericardial administration of cisplatin for neoplastic pericardial effusion and instillation of triamcinolone for autoreactive pericarditis prevent recurrence just as a treatment of several months with colchicine.

Pneumopericardium: an uncommon complication of atrial lead perforation following pacemaker implantation

Cardiac perforation is an infrequent but potentially life-threatening complication of pacemaker implantation. We report a case of right atrial lead perforation complicated by pneumopericardium shortly after pacemaker lead insertion. Transthoracic echocardiography revealed no evidence of pericardial effusion and pacemaker lead displacement, but a thoracic computed tomography scan illustrated the lead course and confirmed the diagnosis. This case suggests that computed tomography is a sensitive modality to confirm the diagnosis at the early stage of this complication.

Intramyocardial Dissecting Hematoma Following Myocardial Infarction

An 80-year-old woman with hypertension and a double aortocoronary bypass 20 years previously was hospitalized with a diagnosis of subacute infarction. At 24 hours after hospitalization, she experienced an onset of heart failure symptoms. Transthoracic color Doppler echocardiography in apical four-chamber view showed features of a neocavity in the laterobasal region (delimited by arrows), with end-diastolic flow in the interior, a communication with the cardiac chamber, and no evidence of pericardial effusion (Figure 1. LA, left atrium; LV, left ventricle; MV, mitral valve). Multidetecter chest computed tomography with electrocardiogram gating was performed, with contrast enhancement in the arterial phase. The study showed a collection communicating with the ventricular chamber, with extravasated contrast in the interior and an ascending course lateral to the left atrium, consistent with myocardial rupture in the laterobasal region (Figures 2 and 3). A decision was made to perform percutaneous closure of the ventricular wall defect by placement of an Amplatzer device, which failed. The procedure was converted to open surgery, which revealed pericardial adhesions and an intramyocardial cavity that did not communicate with the pericardium. Plication of the left ventricular border and tip was performed. Unfortunately, the patient experienced multiorgan failure in the postoperative period and died 72 hours later. Intramyocardial dissection is an uncommon condition that usually occurs in inferoposterior infarctions. Echocardiography and computed tomography are the imaging modalities used for the diagnosis. It is difficult to evaluate the prognosis of these cases or the appropriate management, which should be individualized according to the clinical situation and the experience of the surgical or interventional teams.

Application of rapid ultrasound in shock protocol in the ICU for management of shock.

Sir, One of the most challenging tasks in the Intensive Care Unit (ICU) is to rapidly determine the cause of shock in a critically ill patient and decide the most appropriate treatment in a short time. We describe a case of 34-year-old male with shock and impending respiratory failure presenting to ICU and its management based on information provided by rapid ultrasound in shock (RUSH) protocol. A 34-year-old male patient presented to the ICU with the complaints of recent onset severe dyspnea and dry cough. There was no history of chest pain, fever, and chest trauma. His physical examination revealed tachycardia (pulse rate: 112/min), tachypnea (respiratory rate: 48/min) and hypotension (blood pressure: 80/50 mmHg). Electrocardiogram showed sinus tachycardia, right axis deviation with S1Q3T3 pattern. Patient was intubated and mechanically ventilated in view of impending respiratory failure and shock. Along with initial resuscitation for the shock, she underwent ultrasound according to RUSH Protocol to evaluate the cause of shock. Pump: Grossly enlarged right atrium and right ventricle with D shaped left ventricle. McConnell's sign was present. Pulmonary artery was dilated with pulmonary artery systolic pressure 80 mm of Hg. Left ventricular contractility was adequate. There was no evidence of pericardial effusion or valvular dysfunction. Tank: Inferior vena cava was full and noncollapsing with respiration. Pipes: Deep venous thrombosis screening was done (femoral vein in the femoral canal, popliteal vein in popliteal fossa) which was normal. Screening of the aorta was also normal [Figure 1]. With this information, diagnosis of pulmonary thromboembolism (PTE) causing obstructive shock was considered. Computerized tomography based pulmonary angiography (CTPA) could not be as the patient was on the ventilator and hemodynamically unstable. We thrombolysed the patient with recombinant tissue-type plasminogen activator 100 mg intravenous infused over 90 min. SpO2 with subsequent improvement in hemodynamic parameters. Patient was gradually weaned off the ventilator by 5th day. Subsequently, CTPA showed embolism in the main and segmental branches of both pulmonary arteries. Figure 1 (a) ECG showing S1Q3T3 pattern (b) Chest x-ray showing Palla's sign (prominent right descending pulmonary artery) (c) Dilated right atria and ventricle (d) “D” shaped left ventricle (e and f) Non collapsible IVC seen on m mode (g) Femoral ... Rapid ultrasound in shock protocol is recently proposed systemic algorithm for evaluation of shock.[1] This protocol involves a three-step bedside sonographic assessment simplified as step 1: Evaluation of pump, step 2: Evaluation of tank, step 3: Evaluation of pipes [Table 1]. By focusing on both the anatomy and the physiology, points of care ultrasound by intensivists may help in differentiating between various etiologies of hypotension in the unstable patient. Characteristic ultrasonography finding facilitates the early diagnosis as well as provides prognostic information in PTE.[2,3] These findings needs to be interpreted in the context of the clinical picture as similar finding can be seen in chronic obstructive pulmonary disease, obstructive sleep apnea, pulmonary hypertension and right sided myocardial infarction. The relatively poor sensitivity of ultrasound findings necessitates other investigations to rule out the diagnosis of PTE in critically ill patients.

Acute Aortic Syndrome

An 83-year-old woman presented with mild, nonradiating, central chest pain. The results of her physical examination were unremarkable, and her pulses were symmetrical and bilaterally palpable. Her ECG revealed normal sinus rhythm with no acute ST/T-wave changes. Her transthoracic echocardiogram showed good left ventricular systolic function, with mild dilatation of the ascending aorta (4.5 cm) (Figure 1A), without evidence of pericardial effusion. Figure 1. A , Transthoracic echocardiogram (parasternal long-axis view) showing mildly dilated proximal aorta at 4.5 cm. B , Transthoracic echocardiogram (parasternal short-axis view at aortic valve level) showing large pericardial effusion with the collapse of the right atrium in diastole (thick arrow) suggesting cardiac tamponade.

Ao indicates the proximal aorta; AoV, aortic valve; CT, computed tomography; LA, left atrium; LV, left ventricle; PEff, pericardial effusion; RA, right atrium; and RV, right ventricle. Two hours later, she developed severe chest pain and collapsed. She was cold, clammy, and her blood pressure dropped to 60/30 mm Hg. Her jugular venous pressure was elevated. An urgent bedside transthoracic echocardiogram revealed cardiac tamponade (Figure 1B and 1C). Urgent computed tomography (CT) demonstrated a penetrating atheromatous ulcer (Figure 1D) with a large intramural hematoma. Acute aortic syndrome (AAS) refers to the acute presentation of closely related life-threatening entities having similar clinical features and challenges, including the aortic dissection, intramural hematoma, and penetrating atheromatous ulcer1 (Figure 2).

Pocket-size imaging device: effectiveness for ward-based transthoracic studies

Pocket-size imaging devices (PSID) are now available; their potential role in a hospital environment has been investigated but still remains undefined. We evaluated the effectiveness of PSID in 92 patients referred for bedside transthoracic echocardiogram (TTE). Patients were included where there was a focused clinical question: quantification of left ventricular function (LVF); presence of regional wall motion abnormalities (RWMA); evidence of pericardial effusion, exclusion of significant valve pathology. Each patient underwent an echocardiography evaluation using PSID and TTE. In 83 patients [k = 90%, 95% CI (82.2-95.4)], it was possible to answer the clinical question by PSID examination alone. There was agreement between the findings of PSID and TTE in 86 cases [79%; k = 47%, 95% CI (12.8-82.0)], in three cases, the clinical question was not answered by both modalities. When the clinical question was focused on LVF, the agreement was excellent [k = 96%, 95% CI (95.3-97.9)], as was the agreement in the detection of RWMA [k = 94.57%, 95% CI (82.4-95.1)]. There was also good concordance in the detection of valve pathology and pericardial effusion. Using PSID, the reduction in the scanning and reporting time was 66%. The cost-effectiveness analysis produced very favourable results: with PSE, we obtained an overall cost saving per scan of 76%, compared with TTE. This study demonstrates that PSID can provide a valuable alternative to TTE in the presence of focused clinical questions and can provide an efficient way of delivering a ward-based transthoracic echo service.

Treatment of unilateral fetal pleural effusion by intrauterine thoracocentesis

Fetal pleural effusion refers to an accumulation of fluid in the pleural space. It is most commonly attributed postnatally to chylothorax, a primary lymphatic abnormality. Following the diagnosis of pleural effusion, detailed investigation is essential to exclude other conditions (secondary pleural effusion). The natural history of the lesion is variable. The effusion may resolve spontaneously, remain stable or progress to hydrops and fetal or neonatal demise [1]. The treatment modalities include thoracocentesis, pleuro-amniotic shunting and pleurodesis. The optimal antenatal management is controversial [2,3]. We report a case of isolated pleural effusion diagnosed at 32 weeks of gestation that we successfully treated with thoracocentesis, resulting in a good outcome. The patient was a 30-year-old woman, G2P1A0, referred to our hospital for further management of fetal right pleural effusion at 32 weeks’ gestation. According to the referral information, the pregnancy had been unremarkable until 32 weeks’ gestation. She had not had any illness or recent infectious disease, had not been exposed to teratogenic agents during the pregnancy, and did not have a family history of congenital anomalies. The Down syndrome screen during her second trimester was negative. She had a history of previous cesarean section as a result of preeclampsia and fetal distress. Sonography demonstrated fetal right pleural effusion (Fig. 1). The right lung was compressed and displaced slightly to the midline. There was no evidence of pericardial effusion or gross cardiac defect. There was no other fetal anomaly detectable during the detailed ultrasound examination. One week after the initial visit to our hospital, an increase in the volume of the fetal right pleural effusion occurred. Transabdominal fetal thoracocentesis at 33 2/7 weeks’ gestation was suggested and the patient consented to undergo the procedure. Using a 22-gauge needle and sonographic guidance, 70 mL yellow fluid was removed from the right fetal

Presentation pattern and management of effusive-constrictive pericarditis in Ibadan

Effusive-constrictive pericarditis is a syndrome in which constriction by the visceral pericardium occurs in the presence of a dense effusion in a free pericardial space. Treatment of this disease is problematic because pericardiocentesis does not relieve the impaired filling of the heart and surgical removal of the visceral pericardium is challenging. We sought to provide further information by addressing the evolution and clinico-pathological pattern, and optimal surgical management of this disease. We conducted a prospective review of a consecutive series of five patients managed in the cardiothoracic surgery unit of University College Hospital, Ibadan, in the previous year, along with a general overview of other cases managed over a seven-year period. This was followed by an extensive literature review with a special focus on Africa. The diagnosis of effusive-constrictive pericarditis was established on the basis of clinical findings of features of pericardial disease with evidence of pericardial effusion, and echocardiographic finding of constrictive physiology with or without radiological evidence of pericardial calcification. A review of our surgical records over the previous seven years revealed a prevalence of 13% among patients with pericardial disease of any type (11/86), 22% of patients presenting with effusive pericardial disease (11/50) and 35% who had had pericardiectomy for constrictive pericarditis (11/31). All five cases in this series were confirmed by a clinical scenario of non-resolving cardiac impairment despite adequate open pericardial drainage. They all improved following pericardiectomy. Effusive-constrictive pericarditis as a subset of pericardial disease deserves closer study and individualisation of treatment. Evaluating patients suspected of having the disease affords clinicians the opportunity to integrate clinical features and non-invasive investigations with or without findings at pericardiostomy, to derive a management plan tailored to each patient. The limited number of patients in this series called for caution in generalisation. Hence our aim was to increase the sensitivity of others to issues raised and help spur on further collaborative studies to lay down guidelines with an African perspective.

His body mass index was elevated at 29 kg/m2, and a large cutaneous lipoma was present on his abdominal wall. Transthoracic echocardiography was performed and initially reported to demonstrate a moderate-sized global pericardial effusion (Figure 1 and Movies 1 and 2). Consideration was given to pericardiocentesis; however, subsequent review suggested that the appearances may have been due to pericardial thickening (Movie 3).

LV indicates left ventricle; RV, right ventricle; LA, left atrium; and Ao, aorta.A thick layer of epicardial tissue, measuring up to 29 mm deep, was seen to surround the myocardium on balanced steady-state free precession (SSFP) cine images (Figure 2 and Movie 4). On both SSFP and half-Fourier single-shot fast spin-echo images, signal intensity was high, indeed identical to that from subcutaneous fat. Using a spatial modulation of magnetization sequence (“tagging”), the epicardial tissue appeared to be adherent to the myocardium (Movie 5). The interatrial septum was also markedly thickened (23 mm), with sparing of the fossa ovalis, and had the same high signal intensity (Figure 2C). Fast spin-echo images with a fat-saturation inversion recovery prepulse (which significantly reduces, or “nulls,” the signal from fat) confirmed the epicardial and interatrial septal tissue to be fat (Figure 3). A diagnosis of epicardial lipomatous hypertrophy with concomitant lipomatous hypertrophy of the interatrial septum was made. The pericardium itself was thin and of normal appearance, with no evidence of pericardial effusion; indeed, the contrast provided by the fat allowed for unusually good delineation of the pericardium, highlighting its cranial extension.Download figureDownload PowerPointFigure 2. Cardiovascular magnetic resonance SSFP images. Left ventricular outflow tract (A), short-axis (B), 4-chamber (C), and coronal (D) images showing extensive epicardial lipomatous hypertrophy (asterisk) and lipomatous hypertrophy of the interatrial septum (double dagger). The pericardium (arrows) has a normal appearance, and its cranial extension is particularly evident (D) due to the contrast provided by the fat. RA indicates right atrium; PA, pulmonary artery.Download figureDownload PowerPointFigure 3. Cardiovascular magnetic resonance fat saturation images. In the corresponding fat-saturation fast spin-echo 4-chamber (A, corresponding to Figure 2C) and coronal (B, corresponding to Figure 2D) views, the signal from the epicardial (asterisk) and atrial septal (double dagger) lipomatous hypertrophy is “nulled,” confirming its fatty composition.Cardiac lipomatosis is characterized by the accumulation of nonencapsulated mature adipose tissue caused by hyperplasia of lipocytes. The etiology is unknown, but it may be associated with obesity and advancing age.1 The most frequent manifestation is lipomatous hypertrophy of the interatrial septum. Massive epicardial lipomatous hypertrophy is less well documented. Although histologically benign, it has been reported to cause cardiac tamponade, requiring decompressive pericardiectomy.2 In the presented case, cine imaging demonstrated normal right heart and caval appearances, phase contrast imaging with velocity encoding demonstrated normal systemic venous inflow, and on real-time, free-breathing imaging, ventricular septal motion was seen to be normal, all of which suggested reassuring cardiac filling physiology.The case highlights the possibility of mistaking epicardial lipomatous hypertrophy for pericardial effusion on transthoracic echocardiography. The tissue characterization provided by CMR allowed the diagnosis to be made, avoiding the need for invasive investigation or unnecessary intervention. The functional data provided by CMR suggested that the epicardial lipomatous hypertrophy was not affecting cardiac function.DisclosuresNone.FootnotesThe online-only Data Supplement is available at http://circimaging.ahajournals.org/cgi/content/full/CIRCIMAGING.110.957498/DC1.Correspondence to Dr Christopher Miller, Cardiovascular Magnetic Resonance Unit, North West Regional Cardiac Centre, University Hospital of South Manchester, Southmoor Road, Wythenshawe, Manchester, UK.
