Patients undergoing tricuspid valve replacement who already have a transvenous pacemaker system in the right ventricle are often recommended to have the ventricular lead removed and an epicardial system implanted. However, as a rule, the reliability of endocardial transvenous pacemaker leads has been superior to epicardial systems. Therefore, if the pacemaker lead in the ventricle is still performing well, it may be preferable to leave it in place. In this communication, we present the long-term follow-up results leaving the pacer lead in place by securing it in a position outside the prosthetic valve without interfering with the function of the prosthetic valve.
对于已经在右心室中装有经静脉起搏器系统的三尖瓣置换术患者，通常建议将心室导线取出并植入心外膜系统。然而，一般来说，心内膜经静脉起搏器导线的可靠性优于心外膜系统。因此，如果心室中的起搏器导线仍然性能良好，那么将其留在原处可能更为可取。在本通讯中，我们通过将起搏器导线固定在假体瓣膜外部的位置上，使其不干扰假体瓣膜的功能，从而展示了将其留在原处的长期随访结果。
