The technical difficulty of inserting a sufficiently large prosthesis in a small mitral ring has been overcome by a new technique based on the principle of complete division of the valvular ring and its unrestricted enlargment by reconstruction of the prosthetic valve. Th technique entails division of the aortic valvular ring into and through the mitral anulus and the left atrial wall. It provides wide exposure for easy double mitral and aortic valve replacement, which is performed with large prosthetic valves that are supported in part by the patch reconstruction of the incised structures. This method has been used with excellent technical and good early functional results in two children needing double valve replacement for rheumatic mitral and aortic regurgitation. A wider adoption of this technique to manage similar lesions in both children and adults seems advisable.
一种基于瓣膜环完全分割及通过人工瓣膜重建实现无限制扩大原理的新技术，克服了在小二尖瓣环中植入足够大的人工瓣膜的技术难题。该技术需要将主动脉瓣环分割并穿过二尖瓣环和左心房壁。它提供了广阔的视野，便于轻松进行双二尖瓣和主动脉瓣置换，使用的大型人工瓣膜部分由切开结构的补片重建支撑。该方法已应用于两名因风湿性二尖瓣和主动脉瓣反流需要进行双瓣膜置换的儿童，取得了出色的技术效果和良好的早期功能结果。似乎建议更广泛地采用该技术来处理儿童和成人的类似病变。
