In patients with tetralogy of Fallot (TOF) repair and a borderline pulmonary valve annulus (PVA) size, surgical repair often necessitates a transannular incision and subsequent placement of a patch with or without a monocusp or, alternatively, a right ventricle-to-pulmonary artery conduit. We discuss here a technique in which the pulmonary valve annulus can be safely preserved, with infrequent postoperative issues as well as the potential for less incidence of right ventricular outflow intervention in the long term.
在法洛四联症（TOF）修复和肺动脉瓣环（PVA）大小临界的患者中，手术修复通常需要进行跨瓣环切开术，随后放置补片，或使用单瓣叶，或右心室至肺动脉的管道。我们在这里讨论一种技术，该技术可以安全地保留肺动脉瓣环，术后问题发生频率较低，长期来看，右心室流出道干预的发生率也可能较低。
