Summary
The Ross procedure shows high survival over 25 years, but autograft and homograft dysfunction require monitoring. Identifying high-risk patients through clinical and echocardiographic factors is crucial for long-term management.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Cardiac Valve Surgery
Background:
- The Ross procedure is a complex aortic valve replacement technique.
- Long-term outcomes data are essential for evaluating surgical procedures.
Purpose of the Study:
- To assess the 25-year outcomes of the Ross procedure.
- To identify predictors of adverse events after the Ross procedure.
Main Methods:
- Retrospective analysis of 151 consecutive Ross procedures performed between 1997-2019.
- Long-term clinical and echocardiographic follow-up (median 18 years).
- Analysis of autograft/homograft dysfunction and reintervention rates.
Main Results:
- After 25 years, survival was high (8%), with significant rates of autograft (26%), homograft (32%), and any valve dysfunction (51%).
- Reintervention rates were 15% (autograft), 11% (homograft), and 26% (any valve).
- Early learning curve and larger pulmonary artery diameter predicted autograft issues; younger age predicted homograft dysfunction.
Conclusions:
- The Ross procedure offers good long-term survival but carries non-negligible risks of valve dysfunction and reintervention.
- Clinical and echocardiographic factors can help stratify patients at higher risk for adverse outcomes.
