The patient with aortic stenosis may have reduced left ventricular outflow with a relatively normal valvular architecture and little or no myocardial hypertrophy. For such a patient, surgery directly on the outflow structures may involve serious problems and "trade-offs". Construction of a supplementary conduit from the ventricular apex to the abdominal aorta can provide a valid alternative to more conventional approaches.
患有主动脉瓣狭窄的患者可能存在左心室流出道狭窄，瓣膜结构相对正常，心肌肥厚很少或没有。对于这样的患者，直接对流出道结构进行手术可能会涉及严重问题和“权衡取舍”。从心室尖到腹主动脉构建一条辅助管道可以为更传统的方法提供一种有效的替代方案。
