Prognostic Factors in NOP-LBBB After TAVI

Prognostic Factors in New-Onset Persistent Left Bundle Branch Block After Transcathether Aortic Valve Implantation

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.

Inclusion Criteria:

• New-onset persistent left bundle branch block after transcatheter aortic valve implantation

Exclusion Criteria:

• Pre-existing left bundle branch block
• Pre-existing right bundle branch block
• Pre-existing permanent pacemaker
• Immediate procedural mortality (death ≤72 h post-procedure)
