OF THORACIC SURGERY-April 25, 2025)
1. Study Focus:
• Robotic mitral valve repair was compared to traditional sternotomy in patients aged 65 and older with severe mitral regurgitation (MR).
2. Study Details:
• Data from over 600 patients at a high-volume center were analyzed.
• 189 patients were matched using propensity score matching for fair comparison.
• Median patient age was 70 years; 33.1% were women.
3. Key Findings:
• Operative mortality was very low at 0.3%.
• Robotic patients had longer perfusion (80 min) and cross-clamp times (54 min) compared to sternotomy (52 min and 38 min).
4. Clinical Outcomes:
• Robotic group had:
• Fewer blood transfusions (21% vs. 32%).
• Lower rates of new-onset atrial fibrillation.
• Shorter ICU stays and overall hospitalizations.
• Stroke rates and discharge outcomes were similar between both groups.
5. Echocardiographic Results:
• Recurrent and residual MR was rare in both groups.
• Reintervention rates were very low.
6. Survival Rates:
• Mean survival was excellent: 98% at 3 years, 95% at 5 years, and 92% at 10 years.
• No significant difference in survival or quality of life between robotic and sternotomy approaches.
7. Conclusion:
• Robotic mitral valve repair minimizes physical trauma while maintaining excellent survival and durability.
• It provides a good surgical option for elderly patients with severe MR who are carefully selected.https://www.annalsthoracicsurgery.org/article/S0003-4975(25)00342-X/fulltext
