Permanent pacemaker implantation after On-X surgical aortic valve replacement: SWEDEHEART observational study.

ABSTRACT:

Objective

Bioprosthetic aortic valves with an extended subannular component, such as transcatheter valves, exert increased compression on the cardiac conduction system and increase the risk for permanent pacemaker implantation. It is unknown if the On-X mechanical prosthetic valve, which has an elongated subannular valve housing, increases the risk of permanent pacemaker implantation following aortic valve replacement.

Design

Observational nationwide cohort study.

Setting

Swedish population-based study.

Participants

All patients aged 18-65 years who underwent primary mechanical aortic valve replacement in Sweden between 2005 and 2018. We used the Swedish Web system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Re
