Key result
Simultaneous coronary sinus pacing cuts QRS duration ~20% in a prosthetic tricuspid valve patient.
Why the study?
Complete heart block is a common complication of tricuspid valve replacement, but mechanical valves preclude endocardial right ventricular lead placement.
Population
A 20-year-old female with prosthetic tricuspid valve replacement and postoperative complete AV block

May support dual CS branch pacing for QRS narrowing in tricuspid prosthesis cases; leaves open confirmation in prospective studies.

In patients with a prosthetic tricuspid valve and complete heart block, univentricular bifocal pacing via two electrodes in the coronary sinus is a feasible and effective alternative to epicardial leads to preserve left ventricular function.
Mustafa Yolcu (2020) conducted a case report in Complete heart block with prosthetic tricuspid valve (n=1). Univentricular bifocal pacing via two branches of the coronary sinus vs. Separate pacing of lateral branch and middle cardiac vein was evaluated on QRS duration. Simultaneous pacing from two branches of the coronary sinus reduced QRS duration to 160 ms compared to 200 ms with separate pacing in a patient with a prosthetic tricuspid valve.
