A 15-year old female with William's syndrome became symptomatic for congenital supravalvular aortic stenosis. Surgery was carried out using an unpublished technique which consisted in a symmetrical enlargement of the aortic root by inserting three triangular patches of autologous pericardium. This method has the advantage of restoring normal valvular competence while respecting coronary orifices .
一名患有威廉姆斯综合征的15岁女性出现先天性瓣上主动脉狭窄症状。手术采用了一种未发表的技术，该技术通过插入三块自体心包三角形补片对称扩大主动脉根部。这种方法的优点是在保留冠状动脉口的同时恢复正常的瓣膜功能。
