Objective:
Transcatheter aortic valve implantation (TAVI) is associated with a relatively high incidence of permanent pacemaker implantation (PPM-I). We aimed to evaluate the existing literature on electrocardiographic (ECG) changes before and after TAVI, identify predictors for PPM-I, and suggest a standardized post-TAVI ECG monitoring protocol.
Methods:
A systematic literature review was conducted across multiple databases, including PubMed, Web of Science, and JSTOR, to identify studies published between 2001 and 2024.
Results:
From an initial pool of 24,170 records, 17 studies met the inclusion criteria. Pre-existing right bundle branch block and significant prolongation of ECG intervals were identified as strong predictors of PPM-I. Following TAVI, new-onset left bundle branch block, prolonged PR interval, and QRS complex widening were the most common ECG changes.
Conclusion:
Systematic periprocedural ECG monitoring during TAVI is of paramount importance for the early recognition of conduction abnormalities (CAs) that predict the need for PPM-I.
