Objective: LBBB is not a rare complication after TAVI. Available data on the reversibility of new-onset left bundle
branch block (LBBB) after transcatheter aortic valve replacement (TAVR) in relation to valve type and other factors
remain controversial. We aimed to find out factors that might be responsible for the reversibility of this complication
post implantation.
Method: In this retrospective observational study, we reviewed all TAVI patients operated in our institute from July
2014 to July 2019. We included patients who developed new LBBB post TAVI and excluded patients with preexisting
pacemaker, preoperative LBBB and patients requiring Permanent pacemaker post-operatively during the index
hospitalization. Twelve-lead electrocardiograms at baseline, immediately after TAVI and at 30-days follow-up were
evaluat.. Read More»
