78 patients who underwent disc prostheses replacement, 36 in mitral area, 58 in aortic area were studied by echocardiography. The Authors found 5 cases of malfunction, 3 in mitral area and 2 in aortic area. Regarding mitral malfunctions in 1 case a valve thrombosis was found; in 2 cases there was a partial leak. Regarding aortic malfunctions there was paravalvular leak. In mitral area malfunctions the Authors found alterations of the disc morphology during diastolic opening time associated with alteration of opening time. An increased diastolic closure velocity in 2 cases of paraprosthetic leak was found. A diagnostic element in the case with thrombosis was variability of maximal disc escursion during the same recording, because opening time variability never got over 10 m. seconds. In aortic area malfunctions the Authors found a constant fluttering of anterior mitral leaflet, a sinergic septal motion with the posterior wall and in 1 case the presence of disc opening before the first component of the first sound. The Authors underline the importance of simultaneous eco-phonocardiographic examination and the check-ups for the time to be.
对78例行人工椎间盘置换术的患者进行了超声心动图研究，其中二尖瓣区36例，主动脉区58例。作者发现5例功能障碍，二尖瓣区3例，主动脉区2例。二尖瓣功能障碍方面，1例发现瓣膜血栓形成；2例存在部分渗漏。主动脉功能障碍方面存在瓣周漏。在二尖瓣区功能障碍中，作者发现舒张期开放时椎间盘形态改变与开放时间改变有关。2例人工瓣膜旁漏患者发现舒张期关闭速度增加。血栓形成病例的一个诊断因素是在同一记录过程中最大椎间盘偏移的变异性，因为开放时间变异性从未超过10毫秒。在主动脉区功能障碍中，作者发现二尖瓣前叶持续扑动，与后壁有协同的间隔运动，1例在第一心音的第一个成分之前出现椎间盘开放。作者强调了同时进行超声心动图和心音图检查以及定期检查的重要性。
