“Left atrial myxoma - A tumor in transit”

Abstract

Cardiac myxoma is the most common type of primary cardiac neoplasm. Over 70% of all cardiac myxomas originate from the left atrium (LA) and 18% from the right atrium (RA). Most myxomas present with constitutional, embolic, and obstructive manifestations. We are presenting a case where a part of myxoma got embolized intra-operatively. Using trans-oesophageal echocardiography, we were able to diagnose and image the transit of the tumor from the left ventricle to the left atrium. We removed the embolized tumor from the left atrium and prevented a dreaded complication like stroke, mesenteric ischemia, renal infarct or limb ischemia, which would have resulted in increased morbidity or mortality of the patient.

Surgical treatment of rare pediatric cardiac myxomas:12 years clinical experience in a single institution

“…In our series, the pathological findings of 23 CM were benign in nature. The possibility of recurrence of CM after surgical resection is extremely low, less than 5%, and only a few cases have been recorded [ 14 ]. In this study, there was 1 case of recurrence 5 years after surgery.…”

Incidental Finding of an Exceptionally Large Left Atrial Myxoma Presenting as an Acute Cardioembolic Stroke

“…Despite being extremely rare, cardiac myxomas are the most common primary cardiac tumor, with around 70% presenting in the LA [3,11]. More than half of cardiac myxomas are benign in nature but can manifest with embolic or obstructive symptoms [3,6,9,11].…”

“…The peak incidence of a cardiac myxoma occurs in 50-60year-old females [2]. Proposed etiologies for cardiac myxomas include entrapment of embryonic foregut within the cardiac tissue, allowing for neural and epithelial differentiation [3].…”

Left Atrial Thrombi Masquerading as Myxomas: Mini Case Series and Literature Review

“…Head, neck, chest, abdominal, and pelvic computed tomographic angiography were obtained immediately and revealed no evidence of vascular occlusions or organ infarctions. 1 , 2 This could be only explained by a misdiagnosis of a thrombus, which resolved with anticoagulation, as a myxoma.…”
