The leadless pacemaker is an emerging technology with high efficacy and reduced complications rates. However, due to its novel status, some pitfalls remain to be addressed. We report the case of a 91-year-old patient undergoing a Micra pacemaker implantation. During the procedure, the maneuvers required for the adequate deployment of the device led to damaging of the septal tricuspid leaflet, resulting in severe tricuspid regurgitation. This is a severe mechanical complication of the Micra implantation technique, not previously reported in literature. In light of the novelty of the leadless pacemaker, we should remain cautious with regards to potential unreported complications.

无引线起搏器植入：一种意想不到的并发症

无引线起搏器是一种新兴技术，具有高效率和低并发症发生率。然而，由于其新颖的地位，一些陷阱仍有待解决。我们报告了一例接受 Micra 起搏器植入的 91 岁患者。在手术过程中，装置充分展开所需的动作导致三尖瓣中隔小叶受损，导致严重的三尖瓣反流。这是 Micra 植入技术的严重机械并发症，以前没有在文献中报道过。鉴于无引线起搏器的新颖性，我们应该对潜在的未报告并发症保持谨慎。
