High precision is necessary during percutaneous transcatheter heart valve implantation. The precision of the implantation has been established by increasing the heart rate (usually to 200 beats per minute) to the point of significantly reduced cardiac output and thus minimizing valve movement. Routinely, this tachycardia is induced by rapid pacing. Here we report a case of failure to pace during valve-in-valve (VIV) Edwards Sapien XT implantation in the tricuspid valve position. Transient cardiac arrest was induced by intravenous adenosine injection enabling accurate valve implantation.
经皮经导管心脏瓣膜植入术需要高精度。通过提高心率(通常提高到每分钟200次),使心输出量显著降低,从而使瓣膜运动最小化,以此来确立植入的精度。通常,这种心动过速是由快速起搏诱发的。在此,我们报告一例在三尖瓣位置进行瓣中瓣(VIV)爱德华兹Sapien XT植入时起搏失败的病例。静脉注射腺苷诱发短暂心脏骤停,从而实现了准确的瓣膜植入。
