The presence of both mitral and aortic mechanical prostheses often make access to the left ventricle difficult for hemodynamic evaluation of valve gradients and for performing angiography. We present a case where both the transseptal and direct apical ventricular puncture techniques are utilized for assessing prosthetic valve function. The use of a new over the wire technique for left ventricular access using a flexible 4 French pediatric multipurpose catheter is described.
二尖瓣和主动脉瓣机械瓣膜的存在常常使进入左心室变得困难,不利于评估瓣膜压力阶差的血流动力学情况以及进行血管造影。我们介绍一例通过经房间隔穿刺和直接心尖心室穿刺技术来评估人工瓣膜功能的病例。本文描述了一种使用可弯曲的4法国小儿多用途导管通过导丝技术进入左心室的新方法。
