In keeping with this, Bergsland et al. explored the patency in saphenous vein CABG in which the proximal

anastomoses were performed with automatic connector devices or with a traditional suture technique on 46 patients who underwent OPCAB, using one thoracic graft and one or more saphenous vein grafts.6 Grafts were attached to the aorta with a Symmetry connector in 23 patients, and partial occlusion of Inhibitors,research,lifescience,medical the aorta and sutured anastomoses were used in 23 other patients. Angiography was repeated after 3–5 months. Bergsland et al. showed that 1) Intraoperative graft patency did not differ between the two groups; 2) Vein graft patency decreased to 50% in the Symmetry group, whereas it was 90% in the suture group (P = 0.01); and 3) Twenty-five percent of the Symmetry grafts had significant stenosis in the connector. These observations Inhibitors,research,lifescience,medical stressed the fact that saphenous vein grafts anastomosed to the aorta with the Symmetry

proximal connector had low intermediate patency compared with those with traditionally sutured anastomoses. Importantly, the authors discouraged the routine use of this device in coronary artery Inhibitors,research,lifescience,medical bypass operations. Although clinical practice inclined to reject the use of these devices, other studies reported a positive experience with advanced devices; Diegeler et al. compared the patency rate of the saphenous vein coronary bypass grafts in which the proximal anastomoses were performed with second-generation automatic connector devices to the suture Inhibitors,research,lifescience,medical technique.7 This was examined in 86 patients who underwent CABG with at least one vein graft anastomosed to the ascending aorta with the Symmetry G2 connector. Diegeler et al. reported that 1) Eighty patients had at least one connector successfully implanted; 2) Freedom from cardiac mortality,

myocardial infarction, and target vessel reintervention was 72/80 (90%); 3) Six patients underwent a target vessel reintervention on the connector grafts; 4) Six-month Inhibitors,research,lifescience,medical (mean 193 ± 36 days) angiography patency rates for the connector grafts were 72/81 (88.89%), 37/40 (92.5%) in sutured grafts, and 60/62 (96.8%) in arterial grafts. The authors concluded that saphenous vein grafts anastomosed to the aorta with the Symmetry G2 connector had early and mid-term patency rates comparable to the conventional sutured Carfilzomib anastomoses and that these results supported the efficiency of the second generation of symmetry aortic connectors. ROUTINE USE OF INTRAOPERATIVE EPIAORTIC ULTRASOUND somehow atheroma release from the ascending aorta and proximal arch is a key reason for stroke and neurological injury following cardiac surgery.8 The precise discovery of atheroma before aortic manipulation is required to allow surgical strategies to decrease the risk of embolization.
