We present a successful case of the management of a 46-year-old woman with an abnormal aortic valve formed by four cusps (three equal large cusps and one smaller cusp; type B according to the Hurwitz and Roberts classification) with a marked loss of coaptation that caused a severe aortic insufficiency (AI). The patient underwent an aortic valvuloplasty of the defect using the glutaraldehyde (GA)-pretreated autologous pericardium, restoring the subnormal function and competency of the aortic valve. The postoperative course was unremarkable. The early follow-up showed a trivial AI and a significant reduction of regurgitant volume was identified in a cardiac magnetic resonance imaging (MRI) when compared to the preoperative state (27.2 vs. 2.1 ml). The follow-up transthoracic echocardiography 1 year after the surgery showed mild AI.
我们报告了一例成功的病例，该病例为一名 46 岁女性，其主动脉瓣由四个瓣叶组成（三个等大瓣叶和一个较小瓣叶；根据 Hurwitz 和 Roberts 分类为 B 型），瓣叶对合不良导致严重主动脉瓣关闭不全（AI）。患者接受了使用戊二醛（GA）预处理自体心包的主动脉瓣成形术，恢复了主动脉瓣的亚正常功能和功能。术后过程无特殊。早期随访显示，与术前状态相比，心脏磁共振成像（MRI）显示轻度 AI，且反流容积明显减少（27.2 比 2.1 毫升）。术后 1 年的经胸超声心动图显示轻度 AI。
