From Aug. 13, 1975, through May, 1976, nine patients underwent creation of a left ventricular "vent" for relief of severe left ventricular outflow tract obstruction. A Dacron fabric graft containing a heterograft valve was used to establish a conduit from the left ventricle to the abdominal aorta. There were five male and four female patients in this group; their ages ranged from 4 to 72 years. All had valvular, subvalvular, or supravalvular aortic stenosis, and all but two had undergone previous surgical procedures for relief of the stenosis. All patients survived the operation and none are receiving anticoagulant therapy. All are asymptomatic at present and follow-up is approaching one year. Postoperative cardiac catheterization studies revealed gradients across the aortic valve to be reduced by approximately 90% and mean ventricular systolic pressures by 45%. Although this concept is not new, it has not been used widely and we believe its effectiveness warrants further application.
从1975年8月13日至1976年5月，9例患者接受了左心室“造口”手术，以缓解严重的左心室流出道梗阻。使用含有异种移植瓣膜的涤纶织物移植物建立从左心室到腹主动脉的管道。该组有5名男性和4名女性患者；年龄范围为4至72岁。所有患者均患有瓣膜、瓣膜下或瓣膜上主动脉狭窄，除两名患者外，其余患者均曾接受过缓解狭窄的外科手术。所有患者均存活，且均未接受抗凝治疗。目前所有患者均无症状，随访已接近一年。术后心脏导管检查显示，主动脉瓣两端的压力阶差降低了约90%，平均心室收缩压降低了45%。尽管这一概念并不新鲜，但尚未得到广泛应用，我们认为其有效性值得进一步应用。
