A single-centre cohort and short-term follow-up of patients who developed persistent new onset left bundle branch block after transcatheter aortic valve replacement.

Conclusions: New onset LBBB was frequent conduction problem post TAVR and one-third of patients with new onset LBBB persisted at discharge. New LBBB after TAVR was associated with a higher risk of PPM implantation during the index hospitalisation but not after discharge. Our findings suggest that early PPM implantation for post-TAVR LBBB is not indicated without complete or high degree AV block. Further research is required to identify the patients with new LBBB who would progress to advanced AV block or heart failure. PMID: 31984845 [PubMed - as supplied by publisher]
