The echophonocardiographic features in three patients with a mitral Björk-Shiley prosthesis and paravalvular regurgitation are presented. The characteristic features are an early diastolic humping of the Björk-Shiley disc echo, associated with normal rather than paradoxical septal motion, and a reduced A2-MVO interval. The diagnosis was confirmed at operation in one patient, at cardiac catheterisation and operation in the second, and at necropsy in the third. These features were abolished by surgical correction of the leak in both operated cases.
本文介绍了3例二尖瓣Björk-Shiley人工瓣膜及瓣周反流患者的超声心动图特征。其特征性表现为Björk-Shiley瓣盘回声在舒张早期隆起，伴有正常而非矛盾的室间隔运动，且A2-MVO间期缩短。1例患者在手术时确诊，第2例在心脏导管检查及手术时确诊，第3例在尸检时确诊。在2例接受手术的病例中，通过手术修复渗漏后这些特征消失。
