Atrial Myxoma in Both Chambers: Biatrial or Bilateral? A Rare Case Resected via Endoscopic Approach and Literature Review.

ABSTRACT:

Primary cardiac tumors are exceedingly rare, with myxomas representing the most common benign type among these tumors, predominantly located in the left atrium. Biatrial involvement is an exceptional presentation, reported in less than 2.5% of cases. The terms bilateral and biatrial atrial myxoma are often confused and used interchangeably.

Case presentation

A 52-year-old male with a three-month history of progressive fatigue and exertional dyspnea was found, on transthoracic echocardiography and cardiac MR, to have two intracardiac masses affecting both atria. Intraoperative transesophageal echocardiography co
