Implantation of pacemakers can be challenging in the context of dilated cardiac chambers and valvular regurgitation. We report a difficult case of single chamber pacemaker implantation in a patient with restrictrive cardiomyopathy resulting in grossly enlarged atria and severe tricuspid regurgitation. In this situation, use of a slittable guiding sheath, more typically used for coronary sinus lead implantation, greatly facilitated rapid and stable deployment of the right ventricular lead.
在心脏腔室扩张和瓣膜反流的情况下，植入起搏器可能具有挑战性。我们报告了一例在患有限制性心肌病、导致心房明显扩大和严重三尖瓣反流的患者中植入单腔起搏器的困难病例。在这种情况下，使用通常更常用于冠状窦导联植入的可切开引导鞘，极大地促进了右心室导联的快速稳定植入。
