The impact of NOP-LBBB after TAVR remains controversial and no data exist regarding long-term outcomes. A total of 1,020 consecutive patients without pre-existing LBBB or permanent pacemaker implantation (PPI) undergoing TAVR were included. NOP-LBBB was defined as any new LBBB post-TAVR that persisted at hospital discharge. Follow-up clinical and echocardiographic data were obtained at a median of 3 years (interquartile range: 2 to 5 years) post-TAVR. NOP-LBBB occurred in 212 patients (20.1%) following TAVR. There were no differences between NOP-LBBB and no NOP-LBBB groups, except for a higher use of the self-expandable CoreValve system in the NOP-LBBB group (p  After a median follow-up of 3 years post-TAVR, NOP-LBBB was not associated with a higher mortality or heart failure rehospitalization. However, NOP-LBBB increased the risk of permanent pacemaker implantation and negatively impacted left ventricular function over time. These results should inform future efforts for improving the management of patients with NOP-LBBB post-TAVR.
