RIGHT VENTRICULAR MYXOMA WITH SYNCOPE BY THE OBSTRUCTION OF RJGHT VENTRICULAR OUTFLOW TRACT

Abstract

We report a rare case of right ventricular myxoma that was almost occupying the right ventricular outflow tract. The patient was admitted for syncope, and three-dimensional reconstruction of the heart using multislice spiral computed tomography made apparent a large tumor mass occupying both the right ventricular outflow tract and the proximal main trunk of the pulmonary artery. Invasive right atrial angiography demonstrated a tumor mass rushing back and forward in the right ventricular outflow tract, and mostly blocking blood flow to the pulmonary artery. Based on these findings, the patient underwent successful resection of the right ventricular mass arising from right ventricular anterior papillary muscle. The pathological examination of the mass was consistent with typical myxoma cells.
