TAVI PACER: A Two-step Risk Score for Prediction of Permanent Pacemaker Implantation After TAVI.

TAVI PACER: A Two-step Risk Score for Prediction of Permanent Pacemaker Implantation After TAVI.

The need for permanent pacemaker implantation (PPMI) remains one of the most frequent complications after transcatheter aortic valve implantation (TAVI). This study aimed to develop a novel, two-step risk score to predict PPMI probability after TAVI and to implement it into a user-friendly website. Our risk score addresses the gap in existing data on current prosthesis generations and provides a new and clinically motivated approach to calculating the risk for PPMI.

Inclusion Criteria:

• Patients undergoing TAVI at Deutsches Herzzentrum der Charité between January 2019 and December 2020

Exclusion Criteria:

• previous device implantation
• valve-in-valve procedure
• patients who had received an ALLEGRATM valve (NVT AG, Morges, Switzerland), a LOTUS EdgeTM valve (Boston, Scientific, Natick, Massachusetts), or a CENTERATM valve (Edwards Lifesciences, Irvine, California)
