Clinico-histopathological correlation of symptomatic left main coronary artery electrocardiographic ischemia pattern in a young child with hypertrophic cardiomyopathy

The specific electrocardiographic (ECG) pattern of left main coronary artery ischemia is exceptionally rare in children and under recognized. Occasional reports are bereft of a detailed mechanistic ECG description and limited to dissection, spasm, or anomalous origin of the left main coronary artery. An association with pediatric hypertrophic cardiomyopathy (HCM) is hitherto unreported. We furbish a detailed electrocardiographic description of this entity in the unusual setting of a 4-year-old child with HCM with a restrictive phenotype and exertional symptoms consistent with myocardial ischemia. Heart transplant was performed for this rare indication. Histopathology of the explanted heart in particular revealed left main coronary artery narrowing and provided us with a unique window of opportunity to correlate with clinical findings. The pathophysiology was also likely exacerbated by diffuse sub endocardial ischemia in the milieu of left ventricular hypertrophy with elevated end diastolic pressures. We anticipate that this illustrative case will help contextualize this as well as pediatric scenarios in which the ‘left main ischemia’ ECG pattern can be encountered and foster an accurate electrocardiographic recognition of this entity in children.

462 Accidental detection of an anomalous origin of the coronary arteries in a patient with STEMI: a case report

Abstract Coronary artery anomalies and variants are relatively uncommon congenital disorders of the coronary artery anatomy and constitute the second most common cause of sudden cardiac death in young competitive athletes. Normally there are two main coronary arteries, which stem from the sinuses of Valsalva and descend towards the cardiac apex. The most frequent anomalous origin of the coronary arteries associated with sudden cardiac death is the anomalous origin of a coronary artery from the contralateral sinus, particularly if the anomalous coronary artery has a course between the aorta and the pulmonary artery. The diagnosis of a coronary artery anomaly is insidious since patients are usually asymptomatic. Indeed, in most of the cases, coronary anomalies are discovered incidentally during coronary angiography or on autopsy following sudden cardiac death. However, in some cases, symptoms like angina, syncope, heart failure, and myocardial infarction may occur. We want to describe the case of a 54 years old man who went to another hospital of our district with chest pain. The EKG showed an infero-lateral STEMI. The patient underwent systemic thrombolysis complicated by arrhythmic storm, treated with effective DC shock, then he was urgently transferred to our Hospital to perform a PCI rescue. The coronary angiography showed a critical stenosis of the right coronary artery, treated with the implantation of a zotarolimus-eluting coronary stent system. Surprisingly, an abnormal origin of the anterior interventricular artery and circumflex artery from seperated hosts in the right coronary sinus was detected. A computed tomography showed the separated origin of the right coronary artery and the left main from the right coronary sinus; moreover, the left main presented a retroaortic course between the bulb and the left atrium; the left anterior intraventricular artery run anterior to the aortic root. During hospitalization, a diagnosis of diabetes was made with consequent setting of adequate hypoglycemic therapy. Serial echocardiograms showed an improval in the ejection fraction (from 35–40% to 50%). The patient was discharged in well clinical conditions and 1 month later at the follow-up, during an outpatient visit, he was fully asymptomatic. The dynamic EKG according to Holter showed rare isolated ventricular beats; laboratory tests were normal. The anomalous origin of a coronary ostium from the contralateral sinus is the most frequently anomaly which is associated with sudden cardiac death, in particular when the left coronary artery origins from the right sinus. The rapid advancement of the imaging techniques, including CT, CMR, intravascular ultrasound, and optical coherence tomography, have provided us with a wealth of new information on this subject. Coronary artery CT offers the best performance in terms of spatial resolution, acquisition time, and image contrast but the use is limited due the dose of ionizing radiation and the use of contrast agents, in particular taking into account that most patients are young. CMR is capable of visualizing the origin of the coronary arteries non-invasively, without use of ionizing radiation and contrast agents. Currently however, due to spatial resolution, the capability of CMR to visualize smaller coronary branches is still a limiting factor preventing full assessment of coronary arteries using this modality. Developments and more widespread access to advanced cardiac imaging will undoubtedly lead to earlier diagnoses. The taxonomies of the anomalous origin of coronary arteries are inconsistent and complex and so we want to make our contribution to the register of cases of abnormal origin of coronary arteries for the risk of sudden cardiac death and ischaemic events related to.

447 Left ventricular non-compaction with coronary artery anomaly: incidental diagnosis after ST-elevation myocardial infarction

Abstract Left ventricular noncompaction (LVNC) is a rare congenital cardiomyopathy thought to be caused by arrest of normal endomyocardial morphogenesis. A 33-year-old male, smoker, dyslipidemic not on medical therapy, with family history for sudden cardiac death (SCD) presented to the ER for chest pain radiated to the left arm, unrelated to exertion. The physical examination was within normal limits. Blood tests showed increased cardiac enzymes levels (Troponin I hs 49 308.7 ng/l). The EKG showed STE in the anterior leads and diffuse ventricular repolarization anomalies, suggestive of anterior STEMI. The patient underwent coronary catheterization, with evidence of anomalous origin of the Cx from the RCA and critical stenosis on the proximal LAD, treated with PPCI and implantation of a DES with good angiographic result. The patient was transferred to the Cardiac Intensive Care Unit. TTE showed moderate LV dilatation, severe LV dysfunction (EF 30%) with apical, septal and anterior wall akinesis, and lateral wall hypertrabecularization with multiple prominent trabeculations and deep intertrabecular recesses communicating with the cavity, suggestive for LVNC. Cardiac MRI documented dilated LV with EF 34%, anterior and antero-septal wall akinesis (associated with increased T1 mapping values and areas of LGE after contrast injection, compatible with ischaemic outcomes), infero-lateral wall hypokinesia and LV free wall marked hypertrabecularization with a ratio of not compacted(T)/compacted(M) myocardium of 5 (Petersen criteria for LVNC diagnosis: T/M > 2.3 in telediastolic long-axis view). The patient was discharged in stable clinical conditions in DAPT(Cardioaspirin and Ticagrelor). At two months cardiologic follow-up the patient was asymptomatic and TTE confirmed a dilated LV with severely depressed EF (30%). In consideration of the post-ischaemic dilated cardiomyopathy with severely depressed EF and of the family history of SCD (father deceased at 54-years-old), the patient was admitted in our Cardiology Unit and he underwent subcutaneous ICD (sICD) implantation. He was discharged in stable conditions with remote home monitoring transmitter. The association between LVNC and anomalous coronary artery origin is rare. LVNC is sometimes associated with coronary artery disease, but only rare cases of acute myocardial infarction have been described in literature, with exceptionally rare cases of LVNC incidental diagnosis after STEMI. To the best of our knowledge, this is the first case of LVNC associated with anomalous coronary artery origin and STEMI reported in literature. Some authors hypothesized that a single gene responsible for both myocardial development and coronary endothelium could be involved in the pathogenesis of LVNC and at the same time predispose to coronary atherosclerosis. Further studies are necessary in order to assess the possible pathophysiological mechanisms that correlate LVNC and coronary atherosclerosis. According to European guidelines, LVNC in the absence of additional risk factors is not an indication for primary ICD implantation, and for arrhythmic risk stratification it’s recommended to follow the criteria used for non-ischaemic dilated cardiomyopathy. The anomalous origin of the Cx from the RCA has an incidence of 0.37%, and it is generally not linked to an increased risk of SCD. Involvement of RV in LVNC cannot be excluded even when RV appears normal on CMR, and if involved there is higher risk of perforation by the lead. sICD overcomes disadvantages of transvenous ICD in patients without a need for pacing therapy. In literature use of sICD is reported only in 14 patients with LVNC, mainly children and young adults.

742 Myocarditis after SARS-CoV-2 vaccine: is that so simple?

SARS-CoV-2 vaccination is associated with potential side effects, particularly following second vaccine dose. Recent case series have reported a potential association between SARS-CoV-2 vaccination and acute myocarditis, predominantly in young males. We hereby describe a previously healthy 17-year-old man, with no past cardiac history, who presented to the emergency department with persistent chest pain and fever (up to 38 °C). The patient had received the first dose of Cominarty (BioNTech/Pfizer) vaccine 10 days before symptom onset and reported flu-like symptoms and conjunctivitis involving both eyes one week before administration of the first vaccine dose. On that occasion, no COVID test was performed and the patient was treated with anti-inflammatory drugs and antibiotic eye drops. On admission, laboratory tests were performed (Troponin-I Δ 19 500–23 270 ng/l. CRP 23 mg/dl, ESR 43 s, WBC 17 570 cell/mm3) as well as COVID-19 PCR, Serological tests and Autoimmune disorders panel all resulting negative. CT coronary angiogram did not reveal any spontaneous coronary artery dissection or anomalous origin of coronary arteries and Calcium Score was 0. Transthoracic echocardiography showed a depressed LVEF (36%) with concomitant posterior and inferior wall as well as posterior and anterior basal interventricular septum hypokinesia. Endomyocardial biopsy revealed multifocal lymphocytic myocarditis with sub-endomyocardial and interstitial fibrosis. CMR was also performed (1-week after presentation) demonstrating mildly depressed systolic function (LVEF 47%), with hypokinesia of the posterior and inferior wall, increased signal intensity on T2 maps (58 ms, n.v. <55 ms), prolonged native T1 values (1083 ms, n.v. <1030 ms) as well as subepicardial and intramyocardial LGE enhancement of infero-lateral segments reflecting intercellular fibrosis. Thereafter, the patient was discharged with medical therapy including ACE-inhibitor, colchicine, and ibuprofen. Given the close proximity between SARS-CoV-2 vaccine administration and the absence of other predisposing conditions, the aetiology of myocarditis was attributed to the vaccine. In addition, as the patient suffered from flu-like symptoms and conjunctivitis 1 week before the vaccine, a previous paucisymptomatic SARS-CoV-2 infection was suspected and anti-SARS-Coronavirus Nucleocapsid Protein antibody test revealed high antibody levels with low IgG avidity. Given that myocarditic symptoms evolved after complete Sars-Cov2 symptom resolution, our first hypothesis is that the infection is unlikely to be the cause of acute myocarditis in this patient. Indeed, current literature on COVID-related myocarditis reports close temporal association between respiratory symptoms and myocarditis onset. In support to our hypothesis, recent trials have reported that myocarditis more frequently occurs following administration of mRNA vaccines especially in male adolescents and young adults like our patient. However, cardiac side effects typically occur after full vaccination and symptoms appear within three days following the second dose, which does not fully apply to this case. Notwithstanding this, more recent studies have reported myocarditis even after first vaccination dose in patients with previous COVID-19 infection, analogously to the case described. This case suggests a complex interaction between immunological factors and covid infection/vaccination with potential significant implications on the cardiovascular system. From current literature, much uncertainty remains regarding time interval criteria for reliable post-vaccination myocarditis diagnosis, hence large-scale clinical trials are needed to address this issue.

83 The predictive role of neutrophil-to-lymphocyte ratio in post-operative cardiopulmonary bypass surgery

Abstract Aims Postoperative arrhythmias (POA) are a common complication after cardiac surgical repairs for congenital heart disease (CHD), representing a substantial source of morbidity, mortality, and prolonged total in-hospital stay, with an incidence of 7.5–48% in postoperative pediatric cardiac patients. The etiology is multifactorial, and it has been related to the direct surgical manipulation of the cardiac conduction system, to the local tissue inflammation in the myocardium adjacent to the conduction system and to the arrhythmogenic effects of cardiopulmonary bypass (CPB), inotropes, and electrolyte disturbances. Recently, the prognostic role of neutrophil-to-lymphocyte ratio (NLR), a novel inflammation marker, has been evaluated in pediatric patients after CPB surgery. To evaluate the predictive role of NLR in POA in a population of pediatric CHD patients after CPB. Methods and results We retrospectively collected perioperative clinical and laboratory data of 146 patients (age 8.27 ± 10.79 years; male gender: 60.8%) consecutively admitted to the cardiac surgery intensive care unit (ICU) of our institute after elective cardiac surgery with CPB in 2018. We grouped and analyzed our population over NLR tertiles evaluated at 24 h from CPB and types of POA: supraventricular (SVT) and junctional (JET). The prognostic value of NLR and its association with POA was analyzed. Diagnoses of 146 patients included atrial septal defect (n = 36), ventricular septal defect (n = 20), pulmonary atresia/stenosis (n = 10), tetralogy of Fallot (n = 20), endocardial cushion defect (n = 8), left ventricular outflow tract obstruction (n = 14), anomalous origin of coronary artery (n = 6), complex CHD (n = 13), interrupted/hypoplastic aortic arch (n = 12), anomalous pulmonary venous return (n = 3). The mean CPB time was 121.6 ± 84.6 min. The median ICU hospitalization was 48 h [Q1, Q3: 24, 96]. Twelve patients experienced POA: 6 SVT and 6 JET. The frequency of POA incremented over NLR-tertiles (P-Trend 0.017), while SVT onset was associated with higher values of NLR and C-reactive protein (P = 0.034 and P = 0.011, respectively). Patients in the second and third tertiles of NLR had a prolonged hospitalization (log-rank, P = 0.029), especially when associated with POA (log-rank, P = 0.012). At the multivariable analysis, higher age and NLR values were independently associated with SVT [OR per year 1.22; 95% CI (1.02, 1.25), P = 0.043 and OR per point 1.91; 95% CI (1.29, 2.82), P = 0.012, respectively], but not with JET. Conclusions 24-h post-CPB NLR can predict postoperative SVT in a population of pediatric CHD patients. Our data suggest that the NLR could be a useful, easy-to-obtain marker for postoperative outcome in pediatric patients who had undergone elective CPB.

Anomalous Aortic Origin of Right Coronary Artery: Outcomes of Surgical and Nonsurgical Treatment

BackgroundAnomalous aortic origin of right coronary artery (AAORCA) is a congenital heart lesion that may be associated with coronary ischemia and sudden death; however, the management of these patients remains controversial. The aim of this study was to analyze all patients with AAORCA managed at our center. MethodsThe medical records of patients with an isolated diagnosis of AAOCA were retrospectively reviewed, irrespective of symptoms, from 2007 to 2020. Follow-up was obtained by medical record review. AAORCA was diagnosed by echocardiogram and computed tomographic or magnetic resonance imaging studies in all patients. Treatment was based on anatomic, morphologic, and symptomatic features for patients older than 10 years with AAORCA. ResultsThe review identified 86 patients with a median age of 16 years; of these, 26 (30%) were managed surgically and 60 (70%) are monitored nonsurgically. Surgical intervention included a “classic” unroofing in 10 (39%), neo-ostial creation in 7 (27%), modified unroofing with neo-ostial creation in 6 (23%), a “classic” unroofing with reimplantation in 2 (7%), and reimplantation only in 1 (4%). Surgical patients were significantly older (P = .01), described more chest pain symptoms (P = .004), had the presence of slitlike ostia (P = .03), and longer length of coronary artery narrowing (P = .0002). At follow-up (median, 3 years; range, 0-13 years), 100% of surgical patients underwent functional testing and had no evidence of ischemia. Postoperative evaluation included one or more of echocardiography, computed tomographic angiogram, magnetic resonance imaging, and exercise stress test. ConclusionsOur program uses a systematic approach for patients with AAORCA. With this paradigm, outcomes are excellent in the midterm, as validated with anatomic- and function-based testing.

A Case of Malignant Right Coronary Artery: Frequent Angina in Young Person

Highlight:A young adult has activity-triggered atypical chest pain and diagnosed malignant RCA.Congenital anomalies needed to be aware by cardiologists to help clinical practice.Planning a treatment about management of the CAAs condition should be undertaken by the inter-specialist team. Abstract:We presented a case a young adult with activity-triggered atypical chest pain and diagnosed with anomalous origin of right coronary artery (RCA) from the left coronary sinus with an interarterial course between the aorta and the main pulmonary artery that was detected by CT coronary angiography. This anomaly has been called malignant RCA. Coronary artery anomaly is a congenital condition. Most of the cases remain asymptomatic. This condition is also one of the most causes of sudden cardiac death, because the coronary artery examination is not regularly done. Nevertheless, during high intensity activity, it could be symptomatic and might be lethal. Diagnosing coronary artery anomalies might be tricky and cardiologists must be aware of this. The CAAs condition is a rare situation. The CAAs condition is associated with sudden death, especially intense physical activity. There was no rigid guideline for the management of the CAAs condition, so that planning a treatment in the inter-specialist team should be done.

Diagnosis of adult ALCAPA with computed tomography coronary artery

BackgroundAnomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly where the left main coronary artery arises from the pulmonary artery, instead of the coronary sinus of the ascending aorta. ALCAPA is divided into infant and adult types. Life-threatening complications such as malignant arrhythmia and sudden death could ensue in adult type of ALCAPA. Imaging is the current preferred modality for ALCAPA. It is indeed a challenge to diagnose ALCAPA due to its non-specific clinical presentation and laboratory findings. We report a case of adult type ALCAPA presented with unstable angina surprisingly surviving into adulthood with no symptoms prior to presentation, which is extremely rare.Case presentationA 53-year-old lady presented with sudden onset of chest pain and worsening shortness of breath. She was initially treated as unstable angina. Physical examination revealed normal heart sound. Computed tomography coronary angiography (CTCA) showed an anomalous origin of the left coronary artery from the posterior wall of the proximal pulmonary artery, compatible with ALCAPA. The anomalous left coronary artery bifurcates into left anterior descending and left circumflex arteries. Cardiothoracic surgeon planned for occlusion of ALCAPA via the pulmonary artery, owing to the fact that unfeasible rerouting in the presence of well-established collateral supply.ConclusionsALCAPA is a rare and life-threatening condition in adults which may lead to myocardial infarction and sudden death in untreated cases. CTCA is one of the preferred modern imaging modality in ALCAPA owing to its superior ability for direct visualization of the anomaly. Hence, early identification and surgical intervention of the anomaly are paramount to reduce the morbidity and mortality.

C92. Successful Percutaneous Coronary Intervention (PCI) in Rare Case of Anomalous Aortic Origin of the Right Coronary Artery from the Opposite Sinus (AAORCA) Presenting as Inferior ST Elevation Myocardial Infarction (STEMI)

Abstract Background AAORCA from opposite sinus is a rare congenital anomaly that can present with symptoms similar to coronary artery disease, even sudden cardiac death. AAORCA with Inferior STEMI is a rare combination situation. Management of acute myocardial infarction with AAORCA is not well established and still debatable. Case Summary We presented a case 61 years old aged male with STEMI and AAORCA. He admitted to our hospital with complaint of retrosternal chest pain with ST segment elevation in inferior lead thus we diagnosed as Inferior STEMI. He underwent an emergency coronary angiography (CAG) that showed anomalous of right coronary artery (RCA) and total occlusion of the proximal RCA with atherosclerotic lesion. Stent then implanted at proximal of RCA. Further work-up by Computed Tomography Angiography (CTA) revealed an AAORCA with interarterial course. Discussion AAORCA with interarterial course that presents as inferior STEMI is a rare case. Diagnosis requires CAG and coronary CTA to identify anatomy and physiology so revascularization can be carried out appropriately. It is still arguable whether atherosclerosis or the interarterial course of AAORCA that caused acute MI. There is evidence that anomalous coronary arteries doesn’t increase atherosclerosis risk than normal. Total occlusion located at the distal to interarterial course reinforce that atherosclerosis may be the possible cause of acute MI. PCI could be the preferred choice in patients with inferior STEMI accompanied by AAORCA with evidence of atherosclerotic lesion, because may result in complete reperfusion and good clinical outcome.

Abstract 8918: Nstemi in a Patient With Anomalous Coronary Artery Origin

Introduction: Anomalous origin of the coronary arteries is a rare condition that can be life threatening. We present the case of a patient with anomalous right coronary artery (RCA) origin who presented with atypical chest pain. Case Presentation: A 34-year old man with no medical history presented with atypical chest pain. Initial vital signs were within normal limits and physical examination was unremarkable. Laboratory results revealed a peak troponin of 16.56 Ng/ml and EKG did not show ischemic changes. Echocardiogram demonstrated mildly impaired right ventricular systolic function. Cardiac catheterization showed patent coronaries and anomalous RCA arising from the left coronary cusp (LCC). Cardiac CT showed anomalous origin of the RCA extending from the LCC and coursing between the aorta and the pulmonary artery. Patient remained asymptomatic and was referred for surgical evaluation Discussion: Anomalous RCA originating from the LCC occurs in 0.05%-0.1% of the general population. It may run posterior to the aorta, anterior to the pulmonary trunk, septal or between the pulmonary artery and the aorta itself, like in the case of our patient. Diagnosis of these anomalies can be done by cardiac MRI, cardiac coronary CT, or coronary angiography. Management depends on the nature of the anomalies and remains controversial. Options include coronary angioplasty, conservative medical management, or surgical correction. In patients with intramural course and symptoms of myocardial ischemia, most literature recommends surgical intervention. Conclusions: This case illustrates a unique case of a patient with an anomalous coronary artery origin presenting with NSTEMI. Management can be challenging, and it must be individualized.

Anomalous aortic origin of coronary artery: For a challenging diagnosis, a transthoracic echocardiogram is recommended.

Anomalous aortic origin of a coronary artery (AAOCA), especially the interarterial course of the right or left coronary artery, predisposes paediatric patients to myocardial ischaemia. This rare condition is a leading cause of sudden cardiac death. General paediatricians face challenges when diagnosing this anomaly, and they should pay particular attention to the recurrence of exercise‐related syncope without prodromal symptoms, chest pain and dyspnoea. An accurate transthoracic echocardiogram with Doppler colour flow mapping is the best method to use to identify AAOCA.ConclusionIdentifying an AAOCA is challenging, and we provide advice on clinical red flags and diagnostic approaches for general paediatricians.

A rare unclassified coronary anomaly: Right coronary artery with dual ostia origin from the right aortic sinus of Valsalva

The dual ostia of coronary artery is extremely rare entity. We present a case of old woman with right coronary artery with dual ostia origin from the right aortic sinus of Valsalva. A 52-year-old woman presented with discontinuous chest tightness and palpitation. she was referred to coronary computed tomography angiography (CCTA). The CCTA suggested an anomalous right coronary artery (RCA) origin from the right sinus of Valsalva (RSV) with dual ostia. The dual ostia of coronary anomaly is extremely rare entity. Though catheter angiography may be performed for preoperative identification of coronary anomalies, it is limited in the description of the relationship of the coronary arteries to the cardiac structures and great vessels. CCTA can help in noninvasive characterization of coronary anomalies with respect to their origin, course, and spatial relations. Interventional cardiologists and cardiac surgeons should be aware of the new coronary anomaly for appropriate procedural planning and intra-procedural management. The important imaging valueof CCTA can help in noninvasive characterization of coronary anomalies with respect to their origin, course, and spatial relations.

Direct Reimplantation Procedure in Anomalous Aortic Origin of the Right Coronary Artery: Long-Term Single Center Outcomes.

Anomalous aortic origin of the right coronary artery is known to be a cause of sudden cardiac death in athletes. There are no specific guidelines concerning treatment strategy in the literature. The aim of this study is to describe and report our experience of direct reimplantation technique in the treatment of this anomaly. This was a retrospective single center study of 30 patients who underwent surgery in the congenital heart disease unit of Louis Pradel Heart and Lung Hospital between January 2003 and December 2016. The mean follow-up was seven years (3 months-17 years). Thirty patients underwent surgery. The median age was 17 years (0.2-52 years). There were 24 males. The median weight was 58 kg (3.6-118 kg). Fourteen patients were actively engaged in sports. Twenty-six patients had exertional chest pain or syncope. The median time lapse between diagnosis and intervention was 4.5 months (0.5-179 months). Twenty-seven (90%) patients underwent reimplantation of the anomalous coronary artery without transverse aortotomy, while in 3 (10%) patients transverse aortotomy was used to facilitate reimplantation to avoid tension at the anastomosis. There was no early death; one late death occurred in the third postoperative month. At the last follow-up, all patients had returned to normal physical activity without evidence of ischemia. Direct reimplantation allows for a complete restoration of the coronary anatomy and enables patients to return to normal physical activity. Our study shows encouraging results using a direct reimplantation technique without aortotomy.

The salutary effect of peritoneal dialysis catheters on enhanced recovery among high-risk pediatric patients undergoing the left coronary transfer procedure: a cohort study

BackgroundEvidence for peritoneal dialysis catheter (PDC) usage in pediatric patients undergoing surgery for deteriorating cardiac dysfunction is lacking. This investigation explored factors associated with PDC usage and its effectiveness in children with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA).MethodsEighty-four children undergoing left coronary artery transfer were retrospectively recruited. The primary endpoint was the postoperative ratio of the general ward/[intensive care unit (ICU)] length of stay. Univariable and multivariable analyses were fitted to assess factors related most strongly to PDC and the ratio of general ward/ICU length of stay.ResultsOf the 84 patients, 17 (20.2%) underwent postoperative PDC placement. Patients with extreme cardiac dysfunction [left ventricular ejection fraction (LVEF) ≤25%] were much more likely to require a PDC (OR, 9.88; 95% CI, 2.13–45.76; P = 0.003). Moreover, univariate analysis indicated that concomitant mitral repair significantly decreased the likelihood of PDC placement (OR, 0.25; 95% CI, 0.07–0.85; P = 0.026). In those with cardiac dysfunction (LVEF ≤50%), PDC use was associated with a reduced ratio of ward/ICU length of stay (B, − 1.62; 95% CI, − 2.77– -0.46; P = 0.008), as was age ≤ 12 months (B, − 1.57; 95% CI, − 2.88– -0.26; P = 0.02). At the 1-year follow-up, cardiac improvement was significantly greater in patients with PDC usage than in those without it (P < 0.001), and the number of mitral recoveries was comparable between the groups (64.2% vs. 53.3%, P = 0.434).ConclusionIn cohorts with ALCAPA, PDC placement following surgery may be necessary for patients with extreme cardiac compromise, while concomitant mitral repair can probably reduce their usage rate. PDC is beneficial in conferring an improvement in cardiac and mitral performance. Importantly, after patients are transferred from the ICU, recovery efficiency in the general ward can be enhanced by PDC placement, and hospital discharge can therefore be achieved early, especially for patients younger than 12 months or with LVEF ≤50%.
