Mitral valve repair is a surgical procedure that is used to treat mitral valve disease, which is a condition where the mitral valve in the heart is damaged or not functioning properly. The procedure involves open-heart surgery to fix problems with the valve[1]. Here is a comprehensive overview of mitral valve repair:

Indications for Mitral Valve Repair

• Mitral valve regurgitation: This is a condition where the valve does not close properly, causing blood to flow back into the left atrium of the heart.
• Mitral valve stenosis: This is a condition where the valve becomes narrowed, reducing blood flow through the area[5].

Equipment and Personnel

• The procedure is performed by a cardiac surgeon who specializes in mitral valve repair.
• The equipment used includes a heart-lung machine, which takes over the function of the heart and lungs during the surgery, and a cardiopulmonary bypass machine, which circulates blood through the body during the surgery[2].

Preparation

• Before the procedure, the patient will undergo a series of tests to evaluate their overall health and the extent of the mitral valve disease.
• The patient will also need to stop taking certain medications and avoid eating or drinking for a period of time before the surgery[5].

Technique

• The surgeon will make an incision in the chest to access the heart.
• The surgeon will then put an annuloplasty ring around the valve, which supports the valve and returns it to a more normal shape.
• The surgeon will repair the mitral valve using one or more additional surgical techniques, such as leaflet resection or chordal repair[1].
• After the repair, the surgeon will evaluate the success of the repair and make adjustments if needed[1].

Recovery

• After the surgery, the patient will need to stay in the hospital for several days to recover.
• The patient will need to take medications to prevent infection and manage pain.
• The patient will also need to follow a specific diet and exercise plan to aid in their recovery[1].

Mitral valve repair is generally preferred over replacement, particularly when the valve leaks, because there are more benefits and fewer risks in keeping the patient's own valve[1]. The procedure has a high success rate and is associated with low rates of thromboembolism and resistance to endocarditis[3]. However, patient-specific factors must be taken into consideration when deciding on the best treatment option[2].
