“Double ball valve mechanism obstructing both right ventricular inflow and outflow”: Atypical presentation of right atrial myxoma presenting as right ventricular mass

Abstract

Large intracavitary masses such as those occupying most of a cardiac chamber and obstructing blood flow are not routinely encountered in clinical practice. The differential diagnosis includes neoplastic as well as nonneoplastic causes. Primary cardiac tumors by themselves are uncommon. We hereby report a rare case of a middle-aged female presenting with New York Heart Association Class III symptoms, whose transthoracic echocardiogram revealed a huge mass in right-sided chambers with a novel double ball valve type movement. She successfully underwent urgent surgical resection of the mass with histopathological confirmation of diagnosis.
