The problem of vascular grafts in cardiac surgery is somewhat different from the problems associated with vascular grafts involving larger vessels. Cardiac surgeons must deal with small-caliber grafts exclusively. The diameters of the coronary artery vessels that are usually involved in bypass procedures are about 1 to 2 mm, and occasionally as large as 3 mm. Coronary artery bypass procedures for the most part have been greeted with excellent success. Long-term patency rates of more than 95% using internal mammary arterial grafts and more than 85% for saphenous venous grafts are routinely reported. A prosthetic graft that would permit this order of long-term patency rates would be of enormous usefulness in the field of cardiac surgery.
