Total arterial revascularization of the heart: intentional or inevitable.
The impact of left internal mammary to left anterior descending coronary bypass grafting in enhancing long-term patient survival has led to a widespread interest in arterial grafting over the past decade. It is now accepted that the internal mammary artery is a biologically superior coronary bypass graft compared with the traditional saphenous vein. Experience with other arterial grafts--the right gastro-epiploic artery, the inferior epigastric artery and the radial artery--has shown compelling evidence that they share the same biologic advantage. With the judicious use of some or all of these conduits, all regions of the heart can be reached, and total arterial revascularization is a feasible and desirable objective on a routine basis. As long-term results become available, it is inevitable that it will become the operation of choice.
