“…Only one long-term follow-up clinical report was available, and it revealed graft patency rates of 16% (3/19) at 3-23 months [24]. This is much lower than the reported patency rates for PTFE grafts.…”

Prosthetic grafts are required for coronary artery bypass grafting (CABG) when the availability of suitable autologous conduits is limited. The ideal cardiovascular bypass graft requires a broad range of characteristics including strength, viscoelasticity, biocompatibility, blood compatibility and biostability. Many alternative conduits have been developed and used in the past, but most of them have failed, except in rare instances. This review aims to analyse the current status of their use and prospects for the future. We performed a literature search on PubMed using the generic terms 'conduits for coronary artery bypass grafting'; 'reoperative coronary artery bypass grafting'; 'redo coronary artery bypass grafting'; 'PTFE'; 'Dacron or PET'; 'gastroepiploic artery'; 'inferior epigastric artery'; 'biological grafts'; 'tissue-engineered grafts'; 'synthetic grafts'; 'prosthetic grafts'; 'polyurethane grafts'; 'cephalic veins'; 'short saphenous vein;' and 'alternative conduits'. In addition, we searched through related citations and references from selected articles. A total of 1253 references and 110 full-text articles were reviewed, and they were further selected based on available information. This review concludes that, over the past three to four decades, achieving the goal of a prosthetic graft with equivalent function and durability to the internal mammary artery or long saphenous vein has proved to be elusive.

“…Many smallcaliber vascular grafts for use as CABG conduits have been developed in the past, but most of them have failed. 6,7 Experimental data with low-flow biologic grafts in the aortocoronary position suggest that all types of these grafts are prone to early occlusion. 8,9 The use of BIMA was first reported in 1989 by Suma and colleagues 2 who showed that 4 of 5 BIMA grafts were patent at 2 months.…”

In cases where conventional aortocoronary grafts cannot be used, No-React bovine internal mammary artery is a possible alternative. The aim of this study was to assess the patency and clinical performance of bovine internal mammary artery as a coronary bypass conduit, using 64-slice computed tomography coronary angiography. Eleven patients (mean age, 68.2 + or - 5.9 years) received 11 bovine grafts between 2002 and 2006. Eight of these patients were alive after a mean follow-up of 29.4 + or - 16.3 months. Their mean additive EuroSCORE was 6.5 + or - 3.2. The mean number of distal anastomoses was 2.5 + or - 0.5. Six grafts were anastomosed to the right coronary artery, 2 to the left anterior descending artery, and 3 to the circumflex artery. All 11 bovine grafts were found to be occluded after 14.1 + or - 3.6 months. This demonstrates very poor results with the bovine coronary graft, thus we do not recommend its use, and we suggest considering an hybrid approach in selected cases.

During the last decade many countries have witnessed a dramatic increase in the number of patients undergoing coronary artery bypass grafting. As a consequence, the number of patients with insufficient or inadequate autologous vessels suitable for use as coronary artery grafts is also increasing. These patients may include those who have had previous heart operations, as well as those with bilateral varicose veins and phlebectomy. Given the shortage of autologous grafts, prosthetic and biological conduits are available for use in CABG. However, a small-diameter vascular prosthesis with acceptable long-term patency still remains the cherished wish for cardiovascular surgeons.
