Elevated myocardial extracellular volume fraction as a new predictor of conduction defects after transcatheter aortic valve replacement

Key points Transcatheter aortic valve replacement (TAVR) is now the standard of care for patients with severe symptomatic aortic stenosis (AS). New conduction defects remain a challenge following TAVR in patients requiring permanent pacemaker implantation (PPI). CMRI identified myocardial fibrosis (...

Description
Summary:Key points Transcatheter aortic valve replacement (TAVR) is now the standard of care for patients with severe symptomatic aortic stenosis (AS). New conduction defects remain a challenge following TAVR in patients requiring permanent pacemaker implantation (PPI). CMRI identified myocardial fibrosis (MF) with an increased extracellular volume (ECV) is a new predictor for these conduction defects following TAVR.
