Use of the Ross Procedure in North America: Relation Between Surgical Volume and Operative Mortality - PubMed

3 days ago

Renewed interest in the Ross procedure as an alternative to conventional aortic valve replacement in young adults.
Study assessed trends in Ross procedure utilization and examined the relationship between surgical volumes and operative mortality.
Data from the Society of Thoracic Surgeons Adult Cardiac Surgery Database (2008-2023) was analyzed.
2,268 Ross procedures were reported across 194 centers, with a median age of 43 years.
Ross procedure utilization reached its lowest point in 2017 (63 cases) but increased to 531 cases by 2023.
Ross procedures represented 0.9% of all aortic valve replacements in adults ≤60 years in 2017, increasing to 6.7% by 2023.
Operative mortality declined from 4.4% in 2008 to 1.0% in 2020 but rose to 2.5% in 2023.
Higher center- and surgeon-level Ross volume was associated with lower operative mortality (P < 0.001), with significant improvements beyond 10 cases per year.
Findings support the view that experience plays a key role in achieving optimal results with the Ross procedure.
