Septal artery revascularization

Recurrent angina after coronary artery bypass grafting is due to several factors: graft occlusion, progression of disease, and incomplete revascularization. Of these, incomplete revascularization of diseased but graftable secondary branches of the three major coronary arteries is most amenable to primary surgical treatment. Current operative methods permit endarterectomy or direct bypass grafting (or both) of these smaller vessels. This report details two techniques for revascularization of the anterior septal branch of the left anterior descending coronary artery.
