Mitral Valve Obstruction and Pulmonary Hypertension Caused by a Giant Left Atrial Myxoma Prolapsing in the Left Ventricle

Abstract
Atrial myxomas are the most common primary cardiac tumors to diagnose. They are benign and
have variable presentation. They have an excellent prognosis following surgical excision. We report
a case of a 60 year old female who presented with initial signs of both right and left heart failure,
fever and cough. Auscultation of the heart revealed an apical mid diastolic murmur. Trans-thoracic and trans-esophageal echocardiography revealed a pedunculated, giant left atrial myxoma that prolapsed through the mitral valve into the left ventricle in diastole producing functional mitral valve stenosis. The patient underwent a successful surgical excision of the tumor. The diagnosis and management of atrial myxomas is here reviewed.
