Mitral Valve Obstruction Caused by Heart-shaped Large Left Atrial Myxoma

Myxoma is one of the most common benign primary cardiac tumors, usually detected at ages between 30 and 60 years. It accounts for 50% of the primary cardiac tumors. The most common location of a myxoma is the left atrium. Myxomas are more prevalent in females. The clinical outcomes can differ depending on the tumor's size, location, and architecture. The clinical picture can mimic mitral stenosis, which causes mitral valve obstruction. Syncope is a rare but life-threatening symptom and requires early surgical treatment. This paper describes a patient with a large left atrial myxoma, causing mitral valve obstruction.
