Maze procedure and anomalous coronary artery repair.

A 60-year-old woman has anomalous origin of the left coronary artery from the pulmonary artery, mitral regurgitation with left ventricular dysfunction, and atrial fibrillation. We performed mitral valve annuloplasty, maze procedure, and intrapulmonary tunnel repair of anomalous origin of the left coronary artery. The patient regained normal sinus rhythm and showed improved left ventricular function and no mitral regurgitation.
