The echograms obtained following Björk-Shiley valve replacement are described-first, on an experimental model and later, in vivo. The echogram obtained consisted essentially of four main horizontal waves. Their origin is clarified. In artificially created peri-prosthesis leaks, a normal trace was obtained, while in trans-prosthesis leaks, a reduction in amplitude of motion occurred and the valve remained open in diastole (aortic valve). In vivo, a normal trace was obtained in peri-prosthesis leaks. Trans-prosthesis leaks with the Björk-Shiley valve have not hitherto been described, but the potential of echoscanning in detecting disc dysfunction is put forward.
本文描述了在Björk-Shiley瓣膜置换术后获得的超声心动图——首先是在实验模型上，随后是在活体中。所获得的超声心动图主要由四个主要的水平波组成。其起源已得到阐明。在人工造成的假体周围渗漏中，获得了正常的轨迹，而在假体内部渗漏中，运动幅度减小，并且瓣膜在舒张期保持开放（主动脉瓣）。在活体中，假体周围渗漏获得了正常的轨迹。Björk-Shiley瓣膜的假体内部渗漏迄今尚未见报道，但本文提出了超声扫描在检测瓣膜盘功能障碍方面的潜力。
