Why the study?

Does pacing from specific right ventricular sites improve invasive indices of left ventricular mechanical performance compared to lateral left ventricular pacing in patients with persistent atrial fibrillation?

Population

8 patients (mean age 58 ± 7 years, 2 females) undergoing catheter ablation for persistent atrial fibrillation.

Overview

Certain RV mid-septal sites may outperform LV pacing on LV indices in AF; leaves open outcome benefits in trials.

Structured PICO

Does pacing from specific right ventricular sites improve invasive indices of left ventricular mechanical performance compared to lateral left ventricular pacing in patients with persistent atrial fibrillation?

P
Population
8 patients (mean age 58 ± 7 years, 2 females) undergoing catheter ablation for persistent atrial fibrillation.
I
Intervention
Pacing from different right ventricular (RV) sites mapped to 18 segments using a three-dimensional electroanatomical map.
C
Comparator
Single-site endocardial pacing from the lateral left ventricular (LV) region.
O
Outcome
Invasive indices of LV mechanical performance (SystIndex, DiastIndex, and PPIndex) defined as the ratio of LV dP/dtmax, LV dP/dtmin, and arterial pulse pressure during RV pacing to corresponding values from adjacent periods of LV pacing.surrogate

Invasive hemodynamic measurements demonstrate that the best left ventricular mechanical performance during right ventricular pacing is achieved in the non-apical mid-to-superior septal segments.
