Summary
Minimally invasive aortic valve replacement (AVR) using a hemi-sternotomy approach is safe and effective. This technique offers potential benefits of reduced pain and shorter hospital stays compared to traditional sternotomy.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Surgery
Background:
- Traditional aortic valve replacement (AVR) involves a full sternotomy.
- Alternative approaches aim to reduce surgical trauma and improve patient recovery.
Purpose of the Study:
- To describe and evaluate a technique for AVR using a hemi-sternotomy approach.
- To assess the safety and efficacy of this minimally invasive technique.
Main Methods:
- Nineteen consecutive AVR procedures were performed via hemi-sternotomy.
- Standard cardiopulmonary bypass (CPB) with aortic and right atrial cannulation was utilized.
- Data including aortic cross-clamp time and patient outcomes were prospectively collected and analyzed.
Main Results:
- The mean aortic cross-clamp time was 54+/-13 minutes.
- One patient required conversion to full sternotomy.
- Postoperative transesophageal echocardiography confirmed normal valvular function in all patients, with no neurological events.
- One perioperative mortality occurred due to low cardiac output.
Conclusions:
- Aortic valve replacement via hemi-sternotomy is a safe and feasible minimally invasive option.
- This approach utilizes standard equipment and techniques.
- Potential benefits include reduced sternal trauma, leading to less pain and shorter intensive care and hospital stays.
