Left Atrial Myxoma in a Patient with Pectus Excavatum Case Report and Analysis of Surgical Approach

Myxoma is the most prevalent primary cardiac neoplasm, accounting for 50% of benign heart tumors in adults (1). Elderly women are more predisposed to the development of atrial myxomas, with a ratio of 3: 1 between women and men, and left atrial myxomas are the most common (2, 3). These left-sided tumors predominantly originate in the interatrial septum, at the edges of the fossa ovalis, and can mimic diseases of the mitral valve, presenting a physical examination similar to that observed particularly in valve stenosis (4, 5).
