Artery Bypass Grafting

Heavily calcified ascending aorta significantly increased morbidity and lethality during open-heart surgery. Cannulation and clamping (partial or total) of severely atherosclerotic ascending aorta can easily cause damage and rupture of aortic wall, with consequential distal (often fatal) embolization with atheromatous debris (brain, myocardium). From June 1998. until June 2000, 11 of 2 136 (0.5%) patients who underwent coronary artery bypass grafting were with the severe atheromatous ascending aorta. The site of cannulation was in the aortic arch in three patients (aorta was occluded with Foley catheter in one case, and single clamp technique was used in the other two cases). The femoral artery was the cannulation site in other five cases. Profound hypothermia, ventricular fibrillation, and circulatory arrest, with no cross-clamping or cardioplegia, were used in three patients. Two patients were operated on with extracorporeal circulation, one in normothermia, on the beating heart, the other in moderate hypothermia, on fibrillating heart. In three patients myocardial revascularization was performed on the beating heart, in normothermia, without extracorporeal circulation. Postoperative course was uneventful in all 11 patients. Neither atheroembolism in the peripheral organs, nor atheroembolism of the extramities occurred. The proposed surgical approaches have the potential to reduce the prevalence of stroke and systemic embolization associated with coronary artery bypass grafting in patients with heavily calcified ascending aorta. This result was achieved due to the applied modifications of standard cardiosurgical technique.

Closed-chest totally endoscopic coronary artery bypass grafting (TECAB) is feasible using robotic technology. During the early phases, TECAB was restricted to single bypass grafts to the left anterior descending artery system. Because most patients referred for coronary artery bypass surgery have multivessel disease, development of endoscopic multiple bypass grafting is mandatory. Experimental work on multivessel TECAB was carried out in the early 2000s, and first clinical cases were already performed. With further technological development of operating robots, double, triple, and quadruple TECAB has become feasible both on the arrested heart and on the beating heart. To date, 161 cases of multivessel TECAB using the da Vinci telemanipulation systems are published in the literature. The main advances enabling multivessel TECAB were the availability of a robotic endostabilizer for beating heart procedures and increased surgeon skills using remote access heart-lung machine perfusion and endo-cardioplegia. Both internal mammary arteries can be harvested and both radial artery and vein graft can be used in multivessel TECAB. Y-grafting and sequential grafting are feasible. Multivessel endoscopic surgical revascularization can be combined with percutaneous coronary interventions in advanced hybrid coronary revascularization. Time requirements for multivessel TECAB are significant, and conversion rates to larger thoracic incisions are higher than those observed for single-vessel TECAB. Clinical short- and long-term outcomes, however, seem to meet the standards of open coronary bypass surgery through sternotomy. The main advantages of multivessel TECAB are a completely preserved sternum, use of double internal mammary artery even in risk groups, and a remarkably short recovery time.
