Right Atrial Myxoma Unusual Post-operative Complications

Abstract

This case report concerns a patient with right atrial myxoma who had few features to suggest this diagnosis before cardiac catheterization. Fifteen days after successful removal of the tumor she developed an acute anterior myocardial infarction. Her convalescence from this was complicated by various rhythm disturbances including left atrial rhythm and ventricular tachyarrhythmias. Possible underlying causes which may have been responsible for the development of left atrial rhythm are discussed. The ventricular tachyarrhythmias did not respond to drug therapy but were immediately suppressed by rapid transvenous ventricular pacing.
