Calcification of the pulmonic valve is an uncommon lesion that is usually associated with other congenital cardiac defects. Prior attempts at valvotomy or partial excision of the puolmonic valve have carried a high mortality rate. Pulmonary valve replacement itself is an equally uncommon surgical procedure and, in the past, has been performed only during reconstruction of the right ventricular outflow tract, when the pulmonic valve itself had to be utilized as an aortic prosthesis, and in one patient in whom pulmonary regurgitation following valvotomy was not well tolerated. A case of calcific pulmonic stenosis in association with an atrial septal defect and total anomalous pulmonary venous drainage is reported. The patient was treated successfully by pulmonary valve replacement with a Hancock stented porcine xenograft aortic prosthesis in association with correction of the other congenital cardiac lesions.
肺动脉瓣钙化是一种罕见的病变,通常与其他先天性心脏缺陷相关。以往尝试进行肺动脉瓣切开术或部分切除肺动脉瓣的死亡率很高。肺动脉瓣置换术本身也是一种同样罕见的外科手术,过去仅在右心室流出道重建时进行,此时肺动脉瓣本身必须用作主动脉假体,以及在一名肺动脉瓣切开术后出现肺动脉反流且耐受性不佳的患者中进行。本文报道一例合并房间隔缺损和完全性肺静脉异位引流的钙化性肺动脉狭窄病例。该患者通过使用汉考克带支架猪异种移植物主动脉假体进行肺动脉瓣置换,并同时矫正其他先天性心脏病变,获得了成功治疗。
