Key result
Transvenous AIV pacing maintains stable thresholds and preserved cardiac function at 2 years post-mechanical TVR.
Why the study?
For patients without a left bundle branch block, the optimal position of coronary sinus leads remains controversial.
Does left ventricular pacing through the anterior interventricular vein provide stable pacing and preserve left ventricular function in patients with mechanical tricuspid valve replacement?

Does left ventricular pacing through the anterior interventricular vein provide stable pacing and preserve left ventricular function in patients with mechanical tricuspid valve replacement?
Left ventricular pacing via the anterior interventricular vein is a feasible and reliable alternative for patients with mechanical tricuspid valves, providing stable pacing parameters and preserving left ventricular function.
Wang et al. (2024) conducted a case report in Mechanical tricuspid prosthetic valve requiring permanent pacing (n=1). Left ventricular pacing through the anterior interventricular vein was evaluated on Pacing and sensing thresholds, and left ventricular ejection fraction. Left ventricular pacing through the anterior interventricular vein in a patient with a mechanical tricuspid valve replacement was feasible, providing stable pacing thresholds and preserved cardiac function over 2 years.
