Summary
Minimally invasive direct access (MIDA) heart valve surgery, including aortic valve replacement and mitral valve repair/replacement, demonstrates safety and effectiveness. This approach offers favorable outcomes for patients needing elective aortic or mitral valve procedures.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Surgery
- Heart Valve Repair and Replacement
Background:
- Minimally invasive direct access (MIDA) surgery is an evolving technique for cardiac procedures.
- Evaluating the safety and efficacy of MIDA for aortic and mitral valve operations is crucial for clinical practice.
- Previous studies have explored various minimally invasive approaches, necessitating a review of MIDA's specific outcomes.
Purpose of the Study:
- To review the institutional experience with MIDA heart valve surgery.
- To assess the perioperative and late outcomes of MIDA aortic valve replacement/repair and mitral valve repair/replacement.
- To determine the overall safety and effectiveness of MIDA for isolated elective aortic or mitral valve surgery.
Main Methods:
- Retrospective review of 518 patients undergoing MIDA heart valve surgery.
- Data collection included patient demographics, surgical approach, perioperative complications, and follow-up outcomes.
- Analysis of outcomes for two cohorts: MIDA aortic valve replacement/repair (252 patients) and MIDA mitral valve repair/replacement (266 patients).
Main Results:
- For MIDA aortic valve surgery (250 AVRs): 2% operative mortality, low rates of perioperative complications (e.g., bleeding, infection, stroke), and favorable long-term outcomes with low reoperation and late death rates.
- For MIDA mitral valve surgery (266 cases): 0.8% operative mortality, low perioperative complication rates (e.g., bleeding, stroke, infection), and good long-term results with minimal reoperations and late deaths.
- Significant improvement in New York Heart Association (NYHA) functional class post-operatively for both aortic and mitral MIDA procedures.
Conclusions:
- Minimally invasive direct access (MIDA) heart valve surgery is a safe and effective option for selected patients.
- The MIDA approach yields low operative mortality and morbidity for both aortic and mitral valve interventions.
- MIDA surgery leads to significant functional improvement, supporting its role in elective isolated aortic or mitral valve surgery.
