Among patients with
#AtrioventricularBlock, preserved left ventricular ejection fraction, and anticipated high ventricular pacing burden, left bundle-branch area pacing reduced the 24-month composite of all-cause death, heart failure events, or upgrade to biventricular pacing vs right ventricular pacing.
Device-related complications were similar between groups, supporting clinical consideration of left bundle-branch area pacing for patients expected to require frequent ventricular pacing.
