Prognostic Factors in NOP-LBBB After TAVI

The goal of this observational study is to find prognostic factors in patients with a new-onset persistent left bundle branch block (NOP-LBBB) after transcatheter aortic valve implantation (TAVI). The main question it aims to answer is:Are there any factors influencing heart failure or death risk during the year following TAVI in patients with NOP-LBBB ? Participants will have data collection about TAVI procedure and clinical evolution during a one-year follow-up.
