目的探讨儿童心脏瓣膜置换的有关问题。方法１９９２年３月至１９９７年１２月，对７例儿童进行了心脏瓣膜置换手术，其中二尖瓣置换术５例，主动脉瓣置换术２例，同期修补室间隔缺损３例。结果术后发生急性呼吸功能衰竭１例，急性心包填塞１例，全组无手术死亡。术后随访１～６９个月，患者发育正常，活动量增加。结论儿童换瓣应尽可能选用较大型号的双叶机械瓣，升主动脉根部心包补片加宽及改进缝合技术能使瓣环较小的患儿置入较大型号的心瓣膜。
Objective To investigate the related problems of heart valve replacement in children. Methods From March 1992 to December 1997, seven children underwent heart valve replacement. Among them, 5 were mitral valve replacement, 2 were aortic valve replacement and 3 were ventricular septal defects. Results Postoperative acute respiratory failure in 1 case, acute cardiac tamponade in 1 case, no mortality in the whole group. The patients were followed up for 1 to 69 months. The patients developed normally and their activities increased. CONCLUSIONS: In the selection of children’s valve, larger bileaflet mechanical valve should be used as much as possible. The widening of aortic root pericardial patch and improved suture technique can make a larger heart valve be placed in children with smaller annulus.
