Abstract A retrospective analysis of ten patients with anomalous left coronary artery arising from the pulmonary artery operated between 1979 and 1990 was undertaken. All presented with evidence of left ventricular dysfunction and “ischemic” mitral regurgitation. Surgical repair consisted of an aortopulmonary tunnel (Takeuchi) procedure in eight and direct left coronary artery reimplantation in two. Two patients required postoperative support with a left ventricular assist device. There were no operative or late deaths (CL 0% to 17%) for a follow‐up of over 670 patient months. All patients are in New York Heart Association Class I or II, though two patients are still receiving anticongestive medications. One patient has required further surgery for pulmonary artery stenosis, and another has had a mitral valve replacement because of severe mitral regurgitation. One additional patient has moderate‐to‐severe residual mitral regurgitation and two have a trivial left coronary to main pulmonary artery fistula. All have a patent, nonstenotic left coronary artery and much improved left ventricular function and perfusion as assessed by echocardiography, thallium scan, gated blood pool scan, and angiography. There have been no documented arrhythmias, clinically or on Hotter monitoring. The ECGs have shown resolution or improvement of the initial changes of ischemia/infarction in all patients. Chest X‐rays have shown normalization of cardiothoracic ratio in eight of ten patients. Excellent early and late results can be achieved following timely surgical repair. Marked improvement in left ventricular function has been observed in patients with poor preoperative left ventricular function, even in the presence of extensive ischemia/infarction.
