Volume-outcome relationship of mortality following surgical explant of transcatheter aortic valve replacements.

ABSTRACT:

Objective

To evaluate the relationship between hospital volume of transcatheter aortic valve replacement (TAVR) explants and postoperative mortality.

Methods

The Center for Medicare & Medicaid Services was queried from 2016 to 2024 for patients who underwent TAVR explant. The study period was divided into 2 eras: early (2016-2021) and recent (2022-2024). Hospitals were classified grouped as low volume or high volume. Both 30-day and 1-year mortality were compared, and multivariable analysis was performed.

Results

We identified a total of 123 TAVR explants during the study period. Of the 375 hospitals that performed at least 1 TAVR explant, 235 (63%) performed fewer than 3 explants. Postoperative mortality was 13.3% at 30 days and 18.3% at 1 year. Thirty-day mortality
