The use of the leadless pacemaker system (Micra; Medtronic) has grown in popularity with a lower risk of postimplantation complications associated with traditional pacemakers. We describe the case of a 78-year-old woman who presented with torrential tricuspid regurgitation due to avulsion of the anterior papillary muscle and entire chordal apparatus of the tricuspid valve after Micra pacemaker placement at an outside hospital. After she was deemed ineligible for transcatheter approaches, she underwent a minimally invasive tricuspid valve operation. Although her planned operation was valve replacement, she underwent a successful repair with postoperative echocardiography demonstrating no residual torrential tricuspid regurgitation.
无导线起搏器系统（美敦力公司的Micra）的使用越来越普遍，与传统起搏器相比，植入后并发症的风险更低。我们描述了一名78岁女性的病例，她在外地医院植入Micra起搏器后，因三尖瓣前乳头肌及整个腱索装置撕脱，出现严重的三尖瓣反流。在被认为不适合经导管治疗后，她接受了微创三尖瓣手术。尽管她原计划进行瓣膜置换手术，但最终成功进行了修复，术后超声心动图显示无残余严重三尖瓣反流。
