A modified open patch-graft technique was used to correct congenital pulmonic stenosis in 8 dogs. Pulmonary valve dysplasia was moderate to severe in all cases, based upon clinical and echocardiographic criteria, and 3 dogs were in right-sided congestive heart failure at the time of surgery. Seven of the 8 dogs survived the surgery. One surviving dog displayed cerebral cortical dysfunction, the remaining 6 had no detectable neurological sequelae. Right ventricular failure was alleviated in all 7 surviving dogs, but right ventricular dilatation persisted post-operatively. Pulmonary valvulectomy and open patch-grafting provides an effective means of alleviating signs of congestive heart failure caused by pulmonary valve dysplasia, even in the presence of severe infundibular hypertrophy and dynamic outflow obstruction.
采用改良的开放补片移植技术对8只犬的先天性肺动脉狭窄进行矫治。根据临床和超声心动图标准，所有病例的肺动脉瓣发育不全均为中度至重度，3只犬在手术时存在右侧充血性心力衰竭。8只犬中有7只存活至术后。1只存活犬出现大脑皮质功能障碍，其余6只未发现神经后遗症。7只存活犬的右心室衰竭均得到缓解，但术后右心室扩张持续存在。肺动脉瓣切除术和开放补片移植术是缓解由肺动脉瓣发育不全引起的充血性心力衰竭症状的有效手段，即使存在严重的漏斗部肥厚和动态流出道梗阻。
