Abstract:
A 77-year-old woman with obstructive sleep apnea presented with a 3-week history of leg swelling and dyspnea on exertion. She had a dry cough and lost 10 kg over the past 2 years. Examination revealed elevated jugular venous pressure, reduced air entry in the left lower-lung field, and pedal edema. Imaging with chest computed tomography revealed a giant pedunculated left atrial myxoma to be the cause of her severe pulmonary hypertension, which was reversible with treatment.
