In TAVR recipients with no prior intraventricular conduction disturbances, intraprocedural-HAVB/CHB occurred in 7.4% of cases. HAVB/CHB was persistent in most cases and determined a high rate of PPI post-TAVR. Very high VPR at 1- and 12-month follow-up were observed, which in turn was associated with a negative effect on LVEF. These results support early PPI and close follow-up in patients developing intraprocedural-PHAVB/CHB.
