The aim of this study is to describe electrocardiographic changes and conduction abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI). 76 patients who underwent TAVI using Edwards Sapien 3 prosthesis were included, comparing electrocardiographic registries at admission, post-procedure and before discharge. Patients after TAVI presented a longer PR interval, a wider QRS, and a longer corrected QT, with a left deviation of QRS axis and T waves; reversible changes that tended to correct in the following days after TAVI. Complete atrioventricular block incidence was 2.9%. New-onset left bundle branch block (LBBB) incidence was 39%, although solved in almost half of patients before discharge. TAVI was associated with different reversible electrocardiographic changes that suggest a transient impact on the conduction system. One of every five patients presented permanent LBBB after valve implant. •New-onset conduction disturbances after TAVI are a major issue.•Electrocardiographic changes after balloon-expandable TAVI have been scarcely studied.•Conduction disturbances after balloon expandable TAVI were analyzed.•TAVI was associated with a longer PR interval, a wider QRS, and a longer QT.•New-onset LBBB was frequent with Sapien 3 valve, although solved in half of cases.
