Primary Cardiac Tumors Operated on in Côte d’Ivoire: They Are Almost All Myxomas

Objective: Through this surgical series, we present the epidemiological and anatomical-clinical aspects and the surgical results concerning patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Materials and Method: This is a retrospective descriptive study covering the period of January 1982 to December 2022, based on the medical records of patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Results: Twenty-seven (27) patients underwent surgery for a primary cardiac tumor, including 14 women and 13 men with a mean age of 41.5 years (range 19 - 76 years). The main circumstances of discovery were exertional dyspnea, palpitation and syncope or pseudo-syncope. The main site was the septal wall of the left atrium. The diagnosis of myxoma was confirmed by pathological examination of the surgical specimen in 96.3% (n = 24) of the patients and it was a malignant large cell immunoblastic lymphoma of the myocardium in 3.7% (n = 1) of the patients. The mean largest diameter was 46.1 mm. The postoperative course was marked by an ischaemic stroke (n = 1); recurrence of a left atrial myxoma 5 years after the first tumor removal (n = 1). Two cases of death were noted, one due to the evolution of immunoblastic large cell lymphoma and the other due to an extracorporeal circulation accident. Conclusion: Almost all primary cardiac tumors operated on in Abidjan are myxomas. The circumstances of the discovery of these cardiac tumors are multiple and varied but dominated by exertional dyspnea, palpitation and syncope. Whatever their histological type, primary cardiac tumors are serious affections, in view of the haemodynamic and rhythmic disorders they cause.

Miniincisionl versus Median Sternotomy to the Cardiac Myxoma: A Comparison of Outcomes

Cardiac myxoma are the commonest benign cardiac tumor, its pathological character make it higher tendency for showering and embolic complications. Surgery done on urgent base to avoid its complications.

Anaesthetic Management of Patient with Left Atrial Myxoma, Coronary Artery Disease 3 Vessels Disease, and Parkinson’s Disease

Myxomas are the most common primary benign intracavitatory tumour with the incidence of 0.5 per million populations. Myxomas account for 0.3% of all cardiac surgeries performed. Clinically, they are characterized by a triad of embolisation, obstruction of blood flow, and constitutional symptoms (Goodwin’s triad). Meanwhile Parkinson's disease is a degenerative neurologic disorder caused by degeneration of nerve cells in the substantia nigra causing weakness motor coordination. Symptoms include tremor, bradykinesia, rigidity, and postural instability. Achieving a satisfactory hemodynamic performance is the primary objective in the management of cardiac surgery patient. Optimal cardiac function ensures adequate perfusion and oxygenation of other organ systems (in particular vital organs) and improves the chances for an uneventful recovery from surgery. A 61-year old female diagnosed with Coronary Artery Disease 3 Vessel Disease (CAD 3 VD), Parkinson’s disease, and left atrial myxoma was brought to the emergency department with dyspnea. The patient has undergone angiography and the echocardiography result was LVEF 59% with global normokinetic, LA myxoma causing non-significant mitral flow. LA myxoma excision under general anaesthesia on CPB was planned. Balanced general anaesthesia on cardiopulmonary bypass forms the basis of Anaesthetic management of Cardiac myxomas. However specific individual considerations will have to be made regarding drugs, doses, regional anaesthetic choices, anticoagulation and post-operative management. There is no simple anesthetic technique for patients with Parkinson’. Therefore, careful preoperative assessment, administration of drugs during and after anesthesia, as well as avoiding agents that are known to trigger Parkinson's symptoms is a major factor in reducing postoperative morbidity and mortality.

Left atrial myxoma: an unusual cause of pre-syncope and symptomatic bradycardia

BackgroundAtrial myxomas account for approximately 50% of all primary cardiac tumors. The size, location, risk of embolic event, and involvement of other cardiac structures, are all factors that contribute to the wide range of presentation for cardiac myxomas. Patients with myxomas may remain asymptomatic, while others may report symptoms such as fatigue and fever, dyspnea, and syncope. It is important to recognize arrhythmias as an uncommon symptom of myxomas.Case presentationWe report a rare case of a 67-year-old man who presented with pre-syncopal episodes, symptomatic bradycardia, and night sweats found to have a 5.5 × 5.1 × 3 cm myxoma in the left atrium. During diastole the mass caused dynamic flow obstruction across the mitral valve. The patient underwent surgical resection of the mass given his symptomatology and risk of embolic events. Removal of the myxoma resulted in resolution of both pre-syncopal episodes and the patient’s sinus bradycardia.ConclusionAtrial myxomas are a rare cause of pre-syncope and symptomatic bradycardia. It is important to have a clinical suspicion for atrial myxomas given early diagnosis and surgical intervention are key in improving the prognosis of these patients. This case also highlights the importance of taking into account the source of the myxoma’s blood supply in relationship to other cardiac structures, and further correlating these findings with clinical symptoms.

Case of Dilated Cardiomyopathy in Combination with Left Atrial Myxoma and Left Atriomegaly (Rare Clinical Case)

Case description. A 41-year-old male patient F. was admitted to the Department ofSurgical Treatment of Ac-quired Heart Diseases of the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine with a diagnosis: Dilated cardiomyopathy. Mitral-tricuspid insufϐiciency. Left atrial myxoma. Left atriomegaly. Pulmonary hypertension. The patient was operated with heart failure symptoms of NYHA functional class IV.
 After a week of medical preparation and additional examination,the patient was successfully operated on (remov-al of the left atrial myxoma, imposition of support rings on the left and right atrioventricular openings, paraanular plicacy of the left atrium). The postoperative period proceededwithout signiϐicant complications. On the 12th day after the operation, the patient was discharged in satisfactorycondition. In the remote period the patient died suddenly 3 years later.
 Conclusion. Taking into account the initial serious condition of a patient with advanced heart disease with a reduced left ventricular ejection fraction, left atriomegaly (7.8 cm), pulmonary hypertension (50 mm Hg) and comorbidities, complex reconstruction of the left heart in atriomegaly and ventriculomegaly leads to an improvement in the functional state of the myocardium and morphometric indicators of left atrium and left ventricular ejection fraction.

Features of the Blood Supply of Cardiac Myxoma which Can Cause Bleeding

With a mortality rate of 1 % to 5 %, surgical treatment of cardiac myxomas (CM) may be complicated by the development of intra- or postoperative bleeding, among other things.
 The aim. To present an unusual case of surgical treatment of left atrial myxoma with the occurrence of intraoperative bleeding, which was due to extremely rare features of the coronary circulation with a special blood supply to the base of the CM.
 Case report. Female patient R., 65 years old, case record No.3686, was admitted to the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine with diagnosis of CM. Coronary angiography revealed unique features of coronary circulation: an arteriovenous malformation from the distal parts of the circumflex branch of the left coronary artery with discharge into the right parts of the heart was revealed. On 9/20/2022, urgent operation of resection of the myxoma of the left atrium (LA) was performed. After removal of the myxoma and sealing of the heart, accumulation of arterial blood was found in the area of the inferior vena cava (IVC) and the interatrialsulcus. Revision of the left atrium cavity was performed again:all intracardiac sutures in the area of the myxoma base were duplicated. After repeated resealing of the heart chambers, bleeding from the IVC region stopped after administration of protamine sulfate and tight tamponade of the space under the IVC. Tampons were removed from the pericardial cavity after 72 hours.
 Results. The source of the bleeding could be the site of the malformation of the coronary arteries, which is a tangle of small vessels located in the projection of the base of the myxoma below the point where the IVC meets the right atrium. During the histological examination of the myxoma, large full-blood vessels of the sinusoidal type were revealed, around which, due to damage to their thin walls, hematomas formed, giving the tumor a spotted appearance. The peculiarity of this tumor was the presence of a very large vascular plexus at its base; it had the appearance of a cluster of sections of numerous, different-sized, deformed and remodeled arteries. These data were confirmed by coronary angiography.
 Conclusions. Studying the data of coronary angiography with the analysis offeatures of localization of coronary arteries, as well as the presence of possible coronary malformations, can provide information that allows predicting the possibility of their damage, especially in the case of localization in the place of possible surgical manipulation. In the event of bleeding, one of the optimal methods of its elimination is the use of long-term tamponade.

Cerebral Aneurysms Caused by Atrial Myxoma-A Systematic Review of the Literature.

Background: The association between cerebral aneurysms and left atrial myxoma is known but rare. We described its pathogenesis, clinical presentation, diagnostic findings and treatment using a systemic review of the literature. Methods: MEDLINE via PubMed was searched for articles published until August 2022 using the keywords "atrial myxoma", "cardiac myxoma" and "cerebral aneurysm". Results: In this review, 55 patients with multiple myxomas aneurysms were analyzed, and 65% were women. The average age when aneurysms were diagnosed was 42.5 ± 15.81; most patients were less than 60 years old (86%). Aneurysms could be found before the diagnosis, at the same time as cardiac myxoma, or even 25 years after resection of the atrial mass. In our review, the mean time to diagnoses was 4.5 years. Our review estimates that the most common symptoms were vascular incidents (25%) and seizures (14.3%). In 15 cases, variable headaches were reported. Regarding management strategies, 57% cases were managed conservatively as the primary choice. Conclusions: Although cerebral aneurysms caused by atrial myxoma are rare, the long-term consequences can be serious and patients should be monitored.

659 LEFT ATRIAL MYXOMA IN A PATIENT PRESENTING WITH ACUTE CORONARY SYNDROME: IS EMBOLISM THE PATHOPHYSIOLOGICAL MECHANISM?

Abstract Background Cardiac myxomas, though uncommon, do represent the most frequent primary cardiac neoplasms in human beings. Their clinical presentation is mainly due to flow obstruction, cytokines hyperincretion or embolism. Coronary embolism related to the tumor is a rare finding. Here we describe the case of a left atrial cardiac myxoma with an acute coronary syndrome presentation. Case presentation A 71 year-old woman referred for chest pain, nausea and vomit. On the previous few months she had developed exertional dyspnea and fatigue. No prior history of cardiovascular diseases was reported. The 12-lead ECG showed no significant alterations. Troponin T values were elevated (224 ng/L, normal assay threshold <14 ng/L). Transthoracic echocardiogram displayed left apical akynesia and a bulky left atrial mass protruding through the mitral valve in systole. Coronary angiography showed complete distal occlusion of the left anterior descending (LAD) coronary artery. Thromboaspiration allowed for the retrieval of small-sized non-thrombotic material in the culprit vessel, without angiographic signs of atherosclerotic disease, thus hinting at the embolic nature of LAD occlusion. The patient was then referred to the surgical theatre for removal of the atrial mass, which showed a 4.3×3.4×3.2 cm translucid, lobulated and gelatinous neoformation attached to the interatrial septum via a 1.5×1.2 cm stalk. The mass was surgically removed and the interatrial septum was repaired with a pericardium patch. Hystology was consistent with left atrial myxoma. The hospitalization course was uneventful. Conclusion We reported a case of acute coronary syndrome due to left atrial myxoma. Coronary embolization induced by a cardiac myxoma is rare; however, it should be suspected in patients presenting with myocardial infarction without adjunctive coronary risk factors.

Surgical Outcomes of Cardiac Myxoma Resection Through Right Mini-Thoracotomy.

With recent advances in cardiac surgery through minimal access, mini-thoracotomy has emerged as an excellent alternative for cardiac myxoma resection. This study analyzed the surgical results of this approach, focusing on postoperative cerebral embolism and tumor recurrence. We retrospectively reviewed 64 patients (mean age, 56.0±12.1 years; 40 women) who underwent myxoma resection through mini-thoracotomy from October 2008 to July 2020. We conducted femoral cannulation and antegrade cardioplegic arrest in all patients. Patient characteristics and perioperative data, including brain diffusion-weighted magnetic resonance imaging (DWI) findings, were collected. Medium-term echocardiographic follow-up was performed. Thirteen patients (20.3%) had a history of preoperative stroke, and 7 (11.7%) had dyspnea with New York Heart Association functional class III or IV. Sixty-one cases (95.3%) had myxomas in the left atrium. The mean cardiopulmonary bypass and cardiac ischemic times were 69.0±28.6 and 34.1±15.0 minutes, respectively. Sternotomy conversion was not performed in any case, and 50 patients (78.1%) were extubated in the operating room. No early mortality or postoperative clinical stroke occurred. Postoperative DWI was performed in 32 (53%) patients, and 7 (22%) showed silent cerebral embolisms. One patient underwent reoperation for tumor recurrence during the study period; in that patient, a genetic study confirmed the Carney complex. Mini-thoracotomy for cardiac myxoma resection showed acceptable clinical and neurological outcomes. In the medium-term echocardiographic follow-up, reliable resection was proven, with few recurrences. This approach is a promising alternative for cardiac myxoma resection.

Unusual huge apical left ventricular mass: A diagnostic dilemma

Left ventricular (LV) thrombus and cardiac myxoma are often difficult to be differentiated in transthoracic echocardiography (TTE). Clinical history and findings are crucial in addition to the usage of newer imaging modalities such as transoesophageal echocardiography (TOE) and cardiac magnetic resonance imaging (CMR) in distinguishing these two aetiologies. Management will depend heavily on getting the diagnosis right as this will affect the overall morbidity and mortality of the patient. In this case report, a 52-year-old Malay gentleman, a non-smoker, with a background history of poorly controlled hypertension presented with failure symptoms and sudden chest pain to our center.

Morphological characteristics of cardiac myxoma causing embolism: a series of 40years of experience at a single institute.

Systemic and cerebral embolisms are serious complications of associated with cardiac myxoma. Embolism risk reportedly depends on the gross and histological morphology. This study is aimed at analyzing the morphologic pattern of excised cardiac myxoma as a high-risk embolic cause. Between 1978 and April 2022, 116 surgical specimens of cardiac myxomas were recorded at the pathology department of our hospital. The tumors were classified into three types based on their macroscopic shapes and external morphology-round-smooth, irregular, and villous-to investigate the embolic complications. Of the 116 specimens, 106 macroscopic images of cardiac myxoma (89% were located in the left atrium) were prepared. Round-smooth types were found in 36 (34.0%) patients, irregular types in 32 (30.2%) patients, and the villous types in 38 (35.8%) patients. Multivariable analysis revealed that a villous external appearance was an independent predictor of embolic events (odds ratio: 8.7; 95% confidence interval: 2.4-42.1; p < 0.001). Villous external appearance of cardiac myxoma was associated with the highest risk of distal embolism.

Routine endoscopic robotic cardiac tumor resection using an 8-mm working port and percutaneous cannulation.

Prior studies have demonstrated robotic excision of cardiac tumors as a safe and effective treatment option. The procedure is performed with five incisions: three robotic arm ports, one atrial retractor port, and one working port. We report our unique initial experience in robotic tumor removal. To our knowledge, this is one of the first reports demonstrating cardiac myxoma and fibroelastoma removal with use of exclusively 8-mm ports. All data for robotic cardiac tumor resection at our institution from June 2019 to December 2021 were retrospectively collected; 18 cases were included, including 13 cardiac myxomas and five fibroelastomas. Baseline demographics, intraoperative characteristics, and surgical outcomes were recorded. Descriptive statistics were calculated; continuous variables were reported as median [interquartile range], and categorical variables were reported as percentages. Median patient age was 64 [55, 70] years old. The cohort consisted of primarily female (67%) and white (83%) patients. Median body mass index was 26.3 [23.0, 31.5] kg/m2 . 11% of patients were current tobacco users and 50% had hypertension. All patients underwent myxoma or fibroelastoma removal with the use of five 8-mm robotic ports. Each patient underwent percutaneous cannulation via the femoral arteries. Aortic occlusion was achieved via an endoaortic balloon (67%) or transthoracic cross-clamp (33%). Cross-clamp time was 30 [26, 41] minutes. Concomitant procedures performed during myxoma removal included patent foramen ovale closure (28%), mitral valve repair (8%), left atrial appendage closure (8%), Cox-maze procedure (6%), and coronary artery bypass grafting (6%). All cardiac tumors were packaged with use of the endo-bag and subsequently removed through the working port. Maximal myxoma and fibroelastoma diameters were 2.5 [1.7, 3.5] and 0.6 [0.4, 0.7] cm, respectively. Procedural cardiopulmonary bypass time was 77 [65, 84] minutes. No intraoperative mortality, reoperation for bleeding, or postoperative cardiac issues were recorded. One in-hospital mortality occurred as the result of a thrombotic event in the context of a hypercoagulable state unrelated to the patient's operation. No other mortalities were observed at 30 days. Hospital length of stay was 4.5 [3.0, 7.8] days. In our study, the robotic platform facilitated safe and effective cardiac tumor excision. Our results highlight the efficacy of 8-mm port sizing and the concurrent use of other minimally invasive techniques, including percutaneous cannulation, in this patient population. In general, patients prefer the least invasive treatment option available. Our findings emphasize the importance of training cardiac surgeons to perform robotic procedures using the least invasive means possible to provide patients with various options for their treatment.
