Summary
Mitral valve surgery outcomes were compared between repair (MVV) and replacement (MVR) using standard and small incisions. While certain diagnoses dictated repair or replacement, small incisions were safely used in eligible patients, showing reduced hospital stay without increased mortality.
Area of Science:
- Cardiac Surgery
- Thoracic Surgery
- Minimally Invasive Surgery
Background:
- Mitral valve disease necessitates surgical intervention, with repair (MVV) and replacement (MVR) being primary options.
- Surgical approaches range from standard sternotomy to smaller incisions, impacting patient recovery and outcomes.
Purpose of the Study:
- To evaluate and compare the operative results of mitral valve repair versus replacement.
- To assess the feasibility and outcomes of mitral valve operations performed via standard versus smaller incisions.
Main Methods:
- A retrospective analysis of 821 consecutive patients undergoing mitral valve operations (MVV or MVR) between 1997 and 2002.
- Logistic regression was used to identify risk factors for early mortality and compare repair vs. replacement and standard vs. small incision approaches.
- Patient eligibility for small-incision surgery was determined, and outcomes were compared between those who underwent standard and small-incision procedures.
Main Results:
- Replacement patients were older, more often NYHA class III/IV, and had different primary diagnoses compared to repair patients.
- Overall mortality was 4.0%, with significantly lower rates after repair (2.3%) than replacement (6.4%).
- Eligible patients undergoing small-incision operations experienced shorter hospital stays without increased operative risk (cross-clamp time, perfusion time, mortality) compared to standard incisions.
Conclusions:
- Mitral valve operation mortality is concentrated in specific diagnoses.
- Smaller incisions can be safely utilized for mitral valve surgery in select patients, offering potential benefits like reduced hospital stay without compromising safety.
