Left Ventricular Myxoma: A Case Report

Abstract

Cardiac myxomas are the most common primary cardiac neoplasms, with only a small percentage being found in the left ventricle. Herein, we describe a 25-year-old male who presented with a complaint of chest pain for almost three months and was found to have a 2x2 cm encapsulated tumor attached by a 2-3 mm stalk to the mid-septum, 5 cm below the aortic annulus, via echocardiography. Additionally, a chest CT angiography was performed and revealed a small defect in the left ventricle with a low attenuation density originating from the septum. The tumor was later managed surgically with a median sternotomy approach, and left ventricular myxoma was confirmed histopathologically. Even though cardiac myxomas are incredibly uncommon, they are usually located in the left and right atria and are very unlikely to present in the left ventricle. This incident highlights the importance of taking cardiac myxoma into account as a potential differential diagnosis in cases of chest pain to prevent any further complications.

A Unique Case of a Gigantic Left Ventricular Myxoma Resulting in Embolic Acute Lower Limb Ischemia in a Pediatric Patient

“…However, cases of childhood myxomas have been published in [3][4][5]. When present, myxomas are typically localized in the left atrium [6], but there are few cases of left ventricular myxomas present in the literature [3,[6][7][8][9].…”

“…The preferred diagnostic method is usually transthoracic echocardiography, but thoracic computed tomography might be useful as well. Utilizing cardiac ultrasonography, myxomas can be seen as solitary hyperechoic masses of different sizes and localizations, and they are usually mobile and have a peduncular insertion [8,10,11]. A differential diagnosis with an intracavitary thrombus is mandatory, as it might determine the therapeutic strategy.…”
