Right Atrial Myxoma

Abstract

A case of myxoma of the right atrium with physiologic, surgical, and angio-cardiographic findings has been presented together with a review of six other published cases. Several findings have been emphasized that may call attention to the possible diagnosis of right atrial myxoma; right-sided heart failure; intracardiac calcification of the right heart; enlargement of the right ventricle and right atrium; ecg findings of a prominent P wave and low voltage over right precordium simulating that found in Ebstein''s anomaly and marked variation in heart rate not related to any physiologic event or change in rhythm; use of intracavitary electrode catheter to rule out Ebstein''s anomaly; and finally, analysis of the right atrial curve may lead one to suspect that other than valvular stenosis is present. Angiocardiography gives a definitive diagnosis. Cure may now be obtained with surgical removal of myxomas.
