Atrial septal lipomatous hypertrophy and ischemic heart disease: an unusual presentation.

Lipomatous hypertrophy of the interatrial septum consists of the abnormal accumulation of fatty tissue. We report a patient with unsuspected massive lipomatous hypertrophy of the interatrial septum scheduled to undergo coronary artery surgery. This patient had experienced atrial arrhythmias and obstructive symptoms preoperatively that were ascribed to her coronary artery disease (CAD). The perioperative anesthetic and surgical management of patients with lipomatous hypertrophy of the interatrial septum and CAD is discussed.
