“…From a review of the literature, it appears that about 75% of myxomas are located in the left atrium; 18% of the remainder are found in the right atrium and a smaller number (approximately 6%) in the ventricles, with left ventricular myxomas accounting for 2.5% of all CM cases . Valvular myxomas are extremely rare (<1%), atrioventricular valves being more often involved than the aortic or pulmonary valves; specifically, the mitral valve is the most frequently affected structure, followed by the tricuspid, the aortic and the pulmonary valves .…”

Cardiac myxoma is the most common benign cardiac tumour, localized generally in the left atrium. The majority of cardiac myxomas occur sporadically, while a relatively small proportion of cases develop as a part of Carney complex syndrome. Currently, the histogenesis of myxoma is poorly understood; however, the mesenchymal and endothelial properties of myxoma cells suggest that a clearer understanding of tumour origins can be achieved through a detailed investigation of heart development and endocardial histogenesis. Growing evidence appears to indicate the reactivated expression in cardiac myxoma of genes encoding heart precursor markers, although the exact mechanisms have not yet been described. In this paper we review the most recent scientific literature concerning cardiac embryology and relate this to recent advances in our understanding of the histogenesis of cardiac myxoma. Moreover, given that much of the literature regarding myxoma is of single case reports, we review progress in our knowledge of the pathology and pathogenesis of this condition.

“…[7] Considering the risk for embolization, myxomas should be surgically resected as early as possible. [8] Thrombus formation in LV is a known complication of heart failure and acute myocardial infarction (9,11). Left ventricular thrombus formation in individuals with normal ejection fraction is a rarely seen phenomenon.…”

In this case report, a 29-year young male patient who presented with a history of right sided hemiparesis for 12 hours with no apparent cause. He showed no cough, palpitations, breathlessness, chest pain, syncope, or loss of vision. He had no relevant family history but had a history of two times admission in a National Neuroscience hospital for stroke. Echocardiography showed a freely mobile LV apical mass with hypokinetic apical septum and apex. He underwent successful removal of the mass via the LA roof. The postoperative TEE was normal. Histopathological examination of the resected mass revealed organized thrombus and patient had a satisfactory outcome. Bangladesh Heart Journal 2024; 39(1): 69-72
