Implantation technique of the Cryolife-O'Brien stentless xenograft aortic valve: the simple, rapid, and correct way to implant and the errors to avoid.

摘要: Implantation of the Cryolife-O'Brien Model 300 stentless composite porcine aortic xenograft valve for replacement is different from that other valves. The a symmetrical, composite, three noncoronary leaflet assembly, with broad coaptive surface. Because has only small superior wall cuff and no inferior cuff, single continuous suture line 3-0 polypropylene provides rapid safe implantation in supra-annular position. Consequently ideal recipients are elderly patients, who benefit short cardiopulmonary bypass time. This report describes step-by-step technique outlines principles maintaining symmetry during implantation. Errors to avoid also discussed. been used 267 patients since 1992, 1.1% mortality, low morbidity, excellent function.
