Current controversies in the conduct of the coronary bypass operation
DJ Ullyot
Recent reports comparing medical versus surgical management of patients
with ischemic heart disease highlight the importance of technical quality
in the interpretation of surgical results. This review is an attempt to
examine current controversies in the conduct of coronary artery bypass with
the purpose of suggesting strengths and weaknesses of alternative
approaches. Topics include cold cardioplegia versus intermittent aortic
occlusion, left ventricular venting, anastomotic technique, optical
magnification, "complete vascularization," sequential versus individual
grafting, internal mammary artery versus saphenous vein as conduits and the
choice of alternative conduits when saphenous vein is unavailable.
