Summary
Minimally invasive aortic valve replacement (MIAVR) is safe and effective, showing excellent patient outcomes and survival rates comparable to traditional methods. This approach offers a low conversion rate and reduced perioperative complications.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Procedures
- Aortic Valve Surgery
Background:
- Reports single-center experience with Minimally Invasive Aortic Valve Replacement (MIAVR).
- Procedures performed via right anterior minithoracotomy or ministernotomy (MS).
- Covers patient data from 2002 to 2014.
Purpose of the Study:
- Evaluate the safety and feasibility of MIAVR.
- Assess patient outcomes and survival rates.
- Identify predictors of mortality after MIAVR.
Main Methods:
- Retrospective analysis of 853 patients undergoing MIAVR.
- Kaplan-Meier method for survival evaluation.
- Cox multivariable regression to identify mortality predictors.
Main Results:
- Overall 30-day mortality was 1.9%.
- 1-year and 5-year survival rates were 96% and 80% respectively.
- Predictors of mortality included advanced age, renal failure, and MS approach.
Conclusions:
- MIAVR via minithoracotomy or MS is safe and feasible.
- Excellent outcomes with low conversion and morbidity rates.
- Long-term survival comparable to conventional sternotomy AVR.
