Abstract
The development of left atrial myxoma after coronary artery bypass graft surgery is a rare entity. A 60-year-old man with previous off-pump coronary artery bypass grafting four years ago with patent coronary grafts was diagnosed with left atrial mass. The patient underwent successful resection of the same through minimally invasive right anterolateral thoracotomy. Histopathology of the atrial mass confirmed the diagnosis of atrial myxoma.
Highlights
Atrial myxomas are the most common primary cardiac tumors
We report a patient with left atrial mass attached to posterior wall of left atrium, who underwent coronary artery bypass grafting four years ago with patent coronary artery bypass grafts
Left atrial myxoma developing late following coronary artery bypass grafting with patent coronary grafts have not been frequently reported in literature
Summary
Atrial myxomas are the most common primary cardiac tumors. Cardiac myxomas represent 30-50% of all benign tumours. About 75% originating from the left atrium and 15-20% from the right atrium, near the interatrial septum at fossa ovalis, and occur in all age groups. We report a patient with left atrial mass attached to posterior wall of left atrium, who underwent coronary artery bypass grafting four years ago with patent coronary artery bypass grafts. The patient previously underwent coronary artery bypass grafting four years ago. Computed tomography scan confirmed presence of large, lobulated and hypodense mass in left atrium, measuring approximately 4.00 x 3.50 cm attached to posterior wall. We continued with follow-up of the patient by echocardiography right after surgical treatment, 1Department of Cardiovascular and Thoracic Surgery of U.
