Mitral valve repair is a surgical procedure performed for the management of mitral valve stenosis (narrowing) or regurgitation (leakage). The mitral valve is situated between the two left chambers (left atrium and left ventricle) of the heart. In mitral valve regurgitation, there is improper closure of the mitral valve, allowing the backward flow of blood into the heart. In most cases the defective mitral valve can be repaired. Most of these surgeries are performed through the minimally invasive approach, ensuring a rapid recovery.
Mitral valve repair has several benefits as compared to mitral valve replacement; few of them have been listed below:
- Ensures better long-term survival rates
- Improved lifestyle
- Improved heart function
- Reduced risk of stroke and infection
- Avoids the need for long-term use of blood thinners
There are several different ways to perform minimally invasive mitral valve surgery. Mitral valve surgery can be carried out through a 2-3-inch incision, made over the right side of the chest. The minimally-invasive robotic-assisted valve surgery uses even smaller incisions. In a few patients, another approach, employing an incision over the middle of the chest for better exposure, may be used.
Mitral Valve Repair Surgery — Surgical Techniques
- Mitral Valve Posterior Leaflet Prolapse — Valve Repair Surgery: Posterior leaflet prolapse is most commonly corrected by a triangular resection technique. Here, an abnormal portion of the valve is removed.
- Mitral Valve Anterior Leaflet Prolapse — Valve Repair Surgery: Anterior leaflet prolapse can be corrected by creating artificial cords or by chordal transfer from another part of the valve.
The techniques of mitral valve repair also include annuloplasty, where a partial or C-shaped ring is placed along the circumference of the mitral valve.
