Longitudinal pacing requirements of patients with baseline RBBB who received a prophylactic PPM before TAVR. (a) Heat map of longitudinal ventricular pacing (Vp) requirements over time. The Vp values for each patient are based on at least two electrophysiological device reports in the first year after TAVR that were separate from the TAVR admission. Darker red colors correspond to higher Vp requirements. (b) Distribution of maximal Vp dependence in the first year after TAVR.
Abbreviations: Patient ID, patient identification; PPM, permanent pacemaker; RBBB, right bundle branch block; TAVR, transcatheter aortic valve replacement.
