Management of an Inadvertently Placed Transarterial Pacemaker Lead in the Left Ventricle: A Step-by-step Approach

Inadvertent lead misplacement in the left ventricle can lead to thromboembolic events, valvular damage, and endocarditis. We present a case of an inadvertently placed transarterial pacemaker lead in the left ventricle in a patient who underwent percutaneous lead removal. After a multidisciplinary team discussion involving cardiac electrophysiology and interventional cardiology as well as a discussion of treatment options with the patient, it was decided to proceed with pacemaker lead removal with the Sentinel™ Cerebral Protection System (Boston Scientific, Marlborough, MA, USA) to prevent thromboembolic events. The patient tolerated the procedure well without post-procedural complications and was discharged the next day on oral anticoagulation. We also present a step-by-step approach to perform lead removal with the use of Sentinel™, emphasizing mitigating the stroke and bleeding risks in this patient setting.
