Summary
This study analyzed 1,522 valve procedures, finding repair is often feasible and associated with better survival rates than replacement, though reoperation is more frequent after repair, especially in younger rheumatic mitral patients.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair and Replacement
- Clinical Outcomes Research
Background:
- Valve disease is a significant clinical challenge requiring timely intervention.
- Understanding the comparative outcomes of valve repair versus replacement is crucial for surgical decision-making.
Purpose of the Study:
- To evaluate the efficacy and safety of cardiac valve repair versus replacement in a large patient cohort.
- To analyze outcomes based on valve type, etiology, and surgical approach.
Main Methods:
- Retrospective analysis of 1,522 valve procedures performed between 1988 and 1992.
- Data collection included patient demographics, valve etiology, New York Heart Association (NYHA) functional class, rhythm, surgical procedure (repair vs. replacement), and follow-up outcomes.
- Statistical analysis of hospital mortality, late mortality, embolic events, and reoperation rates.
Main Results:
- Repair was possible in 58.1% of valves, with higher rates for tricuspid (94.5%) and mitral (56.2%) valves compared to aortic (43.6%).
- Hospital mortality was lower for repair versus replacement in isolated mitral (1.5% vs. 5%) and aortic (0% vs. 6.8%) surgeries.
- Actuarial survival at 48 months was higher for repair (94.89%) than replacement (86.84%), but reoperation rates were higher after repair (13% vs. 0.1%).
Conclusions:
- Cardiac valve repair is associated with superior long-term survival and lower operative mortality compared to replacement.
- While repair offers survival benefits, a higher reoperation rate necessitates careful patient selection, particularly in younger patients with rheumatic mitral valve disease.
