The Micra transcatheter pacing system (Medtronic, Minneapolis, MN) is a safe and effective alternative to transvenous pacemaker in selected patients.1, 2, 3 The device was designed with full recapture capability. In 40% of cases, initial deployment of device may result in unsatisfactory electrical parameters, necessitating recapture.4 The tether in the delivery system serves as an important connection between the device and the delivery catheter, allowing multiple recaptures to be performed. This report describes an unexpected event of tether breakage during a difficult recapture attempt, leading to device embolization. Small body build of the patient and apical deployment of the device are postulated as possible contributory factors to this complication.
