Background:
Currently, the leadless pacemaker indications are limited to few and highly selected cases.
Case Summary:
We describe the first reported case of an atrioventricular Micra™ leadless pacemaker implantation complicated by tricuspid posterior leaflet flail with severe regurgitation in a 29-year-old man affected by asymptomatic and progressive high degree atrio-ventricular block. The patient was then treated with endoscopic tricuspid valve repair, leadless pacemaker removal and implantation of an epicardial pacemaker.
Discussion:
Leadless pacemaker complications are multiple, hence it is essential to ensure a safe procedure, especially in the younger patients. We thought that the application of a transesophageal echocardiography guidance might mitigate the risk of major complications.
