[Assessment of proximal aortic anastomosis device in coronary artery bypass grafting]

The aim of this study was to assess the feasibility and safety of a new proximal anastomotic device (PAD) "Enclose II" in coronary artery bypass grafting (CABG). PAD enables the construction of a proximal aortic anastomosis without the use of partial clamp of the ascending aorta, thus reduces the incidence of adverse perioperative neurologic injury related to atheroembolic events. This device was used in 41 off-pump CABG and 11 on-pump beating heart CABG patients for performing 46 radial artery (RA) and 9 vein anastomoses to the aorta. The subjects were 43 males and 9 females, with a mean age of 63.6 years. Thirteen (25%) patients had severe atherosclerotic cerebrovascular lesions preoperatively. The mean flow in the RA graft was 52.4 +/- 26.9 ml/min and that of saphenous vein graft (SVG) was 61.1 +/- 31.9 ml/min. Angiography showed all grafts patent. There was no procedure-related adverse events or cerebrovascular complication. Enclose II device can be a valuable tool to perform RA and vein anastomoses in CABG.
