Abstract
Background
The development of conduction disturbances leading to permanent pacemaker implantation (PPI) remains the main complication of transcatheter aortic valve replacement (TAVR).
Objectives
The aim of this study was to determine the impact of same-day PPI in patients developing persistent complete or high-degree atrio-ventricular block (CHB/HAVB) during TAVR.
Methods
This was a multicenter study including consecutive patients without prior pacemaker and developing procedural persistent CHB/HAVB. Baseline, procedural, and follow-up clinical and pacing interrogation data were prospectively collected in a dedicated database.
Results
A total of 584 consecutive patients (mean age: 81 ± 8 years, 50% of women) were included; 157 (26.9%) had same-day PPI (SDP), and 427 (73.1%) were observed to assess for potential conduction recovery (n-SDP). In the n-SDP group, 376 patients (88%) finally received a PPI at a median of 3 [1-4] days following TAVR. There were no differences in periprocedural complications between groups, including pacemaker pocket hematomas, and the hospitalization length was shorter in the SDP group (5 [2-7] days vs 8[4-9] days; P < 0.001). At 1-month follow-up, the median percentage of ventricular pacing (SDP: 96% (22%-99%), n-SDP: 90% (10%-99%); P = 0.203) and pacemaker dependency rate (SDP: 56%, n-SDP: 50%; P = 0.277) were similar in both groups.
Conclusions
In patients developing procedural persistent CHB/HAVB during TAVR, SDP was safe and associated with a shorter hospitalization length and a very high pacing burden at 30 days. These results, along with the very low rate of conduction recovery in the n-SDP group, would support SDP as a reasonable strategy in these patients.
