Thirty-one adult pig hearts were studied in a pulse duplicator to observe the changes induced by right ventricular outflow tract reconstruction. Six were normal hearts, 7 had a transannular outflow patch and 18 a composite monocusp patch inserted. Abnormal movements and distortion of the posterior pulmonary leaflets were observed when a patch had been inserted. The monocusp patch achieved a competent pulmonary valve although the bovine pericardial cusp had slower movements than the normal leaflet, resulting in a mild regurgitation.
在脉动复制器中对31个成年猪心脏进行了研究，以观察右心室流出道重建引起的变化。其中6个是正常心脏，7个有跨环流出补片，18个插入了复合单瓣补片。插入补片后观察到后肺动脉瓣叶运动异常和变形。尽管牛心包瓣叶的运动比正常瓣叶慢，导致轻度反流，但单瓣补片实现了有效的肺动脉瓣功能。
