Dislodgment and embolization of an atrial leadless pacemaker

The Aveir™ DR Leadless Pacemaker System (Abbott, USA) is the first leadless dual-chamber pacemaker available on the market 1. Due to the communication of two leadless pacemakers, it allows AV synchronous pacing with high reliability 2. Only sparse data is available concerning dislodgment of atrial leadless pacemakers. Two case reports describe the dislodgment of an atrial Aveir™ to the left ventricular outflow tract and to the femoral vein 3,4. However, to the best of our knowledge, this is the first case report of a dislodgement and embolization of an Aveir™ AR pacemaker to the left renal vein in the setting of a severe tricuspid regurgitation.
