Are new-onset persistent LBBB and permanent pacemaker implantation after TAVR associated with increased risk of death and heart failure hospitalization?
Conduction disturbances (NOP-LBBB and PPI) following TAVR significantly increase the 1-year risk of mortality and heart failure hospitalization.
NOP-LBBB and PPI after TAVR are associated with an increased risk of all-cause death and heart failure hospitalization at 1-year follow-up. Periprocedural NOP-LBBB also increased the risk of cardiac death and PPI within the year following the procedure. Further studies are urgently warranted to enhance preventive measures and optimize the management of conduction disturbances post-TAVR.
Faroux et al. (2019) studied this question.
