Key result
LV-only pacing via CS quadripolar lead succeeds in a patient with a mechanical tricuspid valve.
Why the study?
Prosthetic tricuspid valves make permanent pacing challenging.

May enable LV pacing without tricuspid traversal in select patients; hypothesis-generating and requires prospective validation.
Demonstrates the feasibility of placing a quadripolar lead in the coronary sinus with a specific LV sensing algorithm for permanent pacing in a patient with a mechanical tricuspid valve.
Grazina et al. (2024) studied this question. Left ventricle-only pacing via a quadripolar lead in the coronary sinus with a specific sensing algorithm was successfully used in a patient with a mechanical tricuspid valve.
