Pulmonary valve replacement is being performed with increasing frequency in patients with various congenital heart diseases. Chronic pulmonary regurgitation after repair of tetralogy of Fallot is a typical situation that requires pulmonary valve replacement. Chronic pulmonary regurgitation after repair of tetralogy of Fallot can lead to right ventricular dilatation, biventricular dysfunction, heart failure symptoms, arrhythmias, and sudden death. Although pulmonary valve replacement can lead to improvement in functional class and a substantial decrease or normalisation of right ventricular volumes, the optimal timing of pulmonary valve replacement in patients with chronic pulmonary regurgitation is still unknown. There are several options for surgical pulmonary valve replacement. However, no ideal pulmonary valve substitute exists currently and most of the surgically implanted pulmonary valves will eventually require re-replacement. This article will review options and timing of surgical pulmonary valve insertion in patients with chronic pulmonary regurgitation after repair of tetralogy of Fallot.
在患有各种先天性心脏病的患者中,肺动脉瓣置换术的实施频率越来越高。法洛四联症修复术后的慢性肺动脉反流是需要进行肺动脉瓣置换术的典型情况。法洛四联症修复术后的慢性肺动脉反流可导致右心室扩张、双心室功能障碍、心力衰竭症状、心律失常和猝死。尽管肺动脉瓣置换术可使功能分级得到改善,并使右心室容积大幅减小或恢复正常,但慢性肺动脉反流患者肺动脉瓣置换术的最佳时机仍不明确。手术肺动脉瓣置换有多种选择。然而,目前尚无理想的肺动脉瓣替代品,大多数手术植入的肺动脉瓣最终都需要再次置换。本文将综述法洛四联症修复术后慢性肺动脉反流患者手术肺动脉瓣植入的选择和时机。
