Left Atrial Myxoma Presenting with Orthostatic Hypotension in a 30 Year Young Female: A Case Report and Review

Abstract

Sandeep Kumar, Swati Singh and Adil Ahmad Khan

Cardiac tumors are divided into primary and secondary tumors. Primary cardiac tumors are very rare, with an autopsy incidence of 0.001% to 0.03%. Most (>80%) primary cardiac tumors are benign, and myxoma is by far the most common. Myxoma constitutes about 50% of all benign cardiac tumors in adults. Most myxomas (>80%) are found in the left atrium. We report a rare case of a massive left atrial myxoma causing mitral valve obstruction and presenting as positional dizziness. Though cardiac myxomas are known to present with various non-specific clinical symptoms, orthostatic hypotension is not listed as a presenting symptom of atrial tumors in most textbooks of internal medicine or cardiology. So this case is rare in this sense.
