Abstract: Atrial myxoma is the most common primary cardiac tumor. Its clinical presentation varies greatly from asymptomatic incidental mass
to serious life-threatening cardiovascular complications. We herein describe the clinicopathological and imaging features of a huge left atrial
myxoma protruding into the left ventricle during diastole and obstructing diastolic filling of the left ventricle thus causing drop attacks by
prolapsing into the mitral valve. The patient (a 56-year-old female) underwent emergency surgery with complete removal of a 74 g weighing
myxoma from the left atrium. She recovered without any complications. Awareness of this uncommon acute presentation of atrial myxoma is
necessary for timely diagnosis and prompt surgical intervention to avoid irreversible cardiovascular complications. (IJCEP1208009).
