Case Report

Abstract

This report describes a case of giant left atrial myxoma in a 43-year-old woman. She presented with general malaise and dyspnea. Electrocardiogram showed severe right-axis deviation. Transthoracic echocardiography demonstrated a giant mobile mass with size of 6.5 × 4.5 cm in the left atrium. This mass protruded into the left ventricle in diastole and disturbed transmitral left ventricular filling flow. Bilateral atrium and right ventricle were dilated. Severe tricuspid regurgitation was demonstrated with peak pressure gradient of 91 mmHg. This mass was surgically excised and was diagnosed as benign atrial myxoma by histological analysis. Pulmonary hypertension was improved after surgery.
