A new left ventricular outflow tract prosthesis is described. It consists of a tightly woven Dacron graft with one end modified by being wrapped around a thin perforated stainless steel tube to form a rigid left ventricular insertion port and the other end anastomosed to a Hancock xenograft valved conduit for suture to the arterial system. The prosthesis is simple in design and flexible enough to permit anastomosis to any portion of the abdominal aorta. In addition, since the entire blood conduit consists of a porous woven arterial graft and a tissue valve, anticoagulants are not required. The prosthesis has been successfully employed in a 7-year-old boy who had undergone two previous open-heart operations for resection of a subaortic ring but who had persistent evidence of severe residual stenosis. We believe this conduit has advantages over present commercially available units.
本文描述了一种新型左心室流出道假体。它由紧密编织的涤纶移植物组成，一端通过缠绕在一根细的多孔不锈钢管上进行改良，形成一个刚性的左心室插入端口，另一端与一个带瓣膜的汉考克异种移植物导管吻合，以便缝合到动脉系统。该假体设计简单且足够灵活，能够与腹主动脉的任何部位进行吻合。此外，由于整个血液导管由多孔编织动脉移植物和组织瓣膜组成，因此不需要使用抗凝剂。该假体已成功应用于一名7岁男孩，他此前曾接受过两次心脏直视手术以切除主动脉下环，但仍有严重残余狭窄的持续证据。我们认为这种导管比目前市售的产品具有优势。
