Left Ventricle only single lead pacing in a patient with a tricuspid mechanical valve and a previous coronary sinus malfunctioning lead

Abstract

Prosthetic tricuspid valves make permanent pacing challenging. We describe a case of a patient with several previous heart surgeries with a mechanical tricuspid valve and a previous malfunctioning left ventricle lead and recurrent syncope. A quadripolar lead was placed in the coronary sinus, using a specific left ventricle sensing algorithm.
