Key result
Visualizing the tricuspid valve annulus during HBP reduces fluoroscopy time ~30% vs standard placement.
Why the study?
His bundle pacing adoption is limited by longer procedure times and frequent high capture thresholds, prompting evaluation of whether a novel imaging technique improves implantation.
Does His bundle pacing implantation with visualization of the tricuspid valve annulus reduce fluoroscopic time in patients with standard pacing indications?
RCT (n=50)
Does His bundle pacing implantation with visualization of the tricuspid valve annulus reduce fluoroscopic time in patients with standard pacing indications?
Absolute Event Rate: 7.1% vs 10.1%
p-value: p=0.03
Visualization of the tricuspid valve annulus via contrast injection significantly reduces procedural and fluoroscopic times during His bundle pacing implantation.

Reduces fluoroscopy time in HBP implantation; extends RCT evidence for techniques to overcome procedural barriers in physiological pacing.
Gu et al. (2020) conducted an RCT in standard pacing indications (n=50). His bundle pacing with visualization of the tricuspid valve annulus vs. standard method was evaluated on fluoroscopic time for HBP lead placement (minutes) (p=0.03). His bundle pacing with visualization of the tricuspid valve annulus significantly reduced fluoroscopic time for lead placement compared to the standard method (7.1 vs 10.1 minutes, P=0.03).
