Impact of pre-existing conduction abnormalities on permanent pacemaker implantation after transcatheter aortic valve replacement: A meta-analysis

Table 6 Long-term pacing dependency data across included studies

Ref.	n (PPM)	Follow-up	Dependency rate	Definition/notes
Naveh et al[21] (2017)	38	6-12 months	68.4%	Long-term pacing dependency
Van Gils et al[29] (2018)	66	6 months	61%	> 20% ventricular pacing
Meduri et al[28] (2019)	245	1 year	50%	83% of 30-day dependent remained so at 1 year
Dizon et al[31] (2015)	173	1 year	51% paced ECGs	95% RV-paced morphology
Wasim et al[30] (2025)	173	Follow-up visits	38%	PM dependency during follow-up
Guetta et al[20] (2011)	28	3 months	40%	HDAVB persisting at 3-month check
Fraccaro et al[33] (2011)	25	6 months	23.5%	> 95% pacing; mean burden 19% in remainder
Kostopoulou et al[32] (2015)	10	24 months	40%	60% recovered endogenous rhythm by 1 month
Bagur et al[23] (2012)	30	Discharge	80% paced rhythm	Long-term dependency not formally reported

PPM: Permanent pacemaker; PM: Pacemaker; RV: Right ventricular; ECG: Electrocardiogram; HDAVB: High-degree atrioventricular block.
