The Fontan procedure has afforded improved surgical repair for several complex congenital cardiac defects, including tricuspid atresia and single ventricle. Through surgical creation of a connection between the RA and the RV or PA, adequate pulmonary perfusion can be achieved without an RV. Although it is not an anatomic connection, the Fontan procedure is a more physiologic approach than the previously used shunt procedures. Systemic venous return and PVR are effectively separated within the heart, pulmonary blood flow is assured through an RA-to-PA connection, and ventricular volume overload is avoided. The procedure has been effective in relieving cyanosis and has resulted in improved levels of exercise tolerance after surgery.
Fontan手术为包括三尖瓣闭锁和单心室在内的几种复杂先天性心脏缺陷提供了更好的手术修复方法。通过手术在右心房和右心室或肺动脉之间建立连接，在没有右心室的情况下也能实现足够的肺灌注。尽管这不是一种解剖学连接，但Fontan手术比以前使用的分流手术更符合生理。体循环静脉回流和肺血管阻力在心脏内有效分离，通过右心房到肺动脉的连接确保肺血流，避免心室容量过载。该手术在缓解紫绀方面有效，并提高了术后的运动耐量。
