Mitral Valve Clip
A mitral valve clip is a minimally invasive procedure used to treat a leaking mitral valve, a condition known as mitral regurgitation. The mitral valve functions like a gate, allowing blood to flow from the upper to the lower left chamber of the heart. When the valve does not close properly, blood can leak backward into the upper chamber and even into the lungs, leading to symptoms such as breathlessness, fatigue, or swelling.
Mitral regurgitation, if left untreated, may progress and lead to complications like atrial fibrillation or heart failure. During the mitral valve clip procedure, a specially designed clip is delivered to the heart via a catheter inserted through a vein. The clip is positioned on the mitral valve to reduce the leak and restore proper valve function.
What does it do?
The mitral valve clip helps close the part of the valve that is leaking, allowing more blood to flow in the correct direction with each heartbeat. By reducing the backward flow (regurgitation), the heart doesn’t have to work as hard, and symptoms like shortness of breath, dizziness, and leg swelling can improve significantly.
This procedure can be especially beneficial for patients who are too high-risk for open-heart surgery.
How does it work?
The mitral valve clip procedure is performed without open-heart surgery. A catheter is inserted through a vein in the groin and guided to the heart using real-time imaging. The clip is then attached to the defective section of the mitral valve using a technique called “edge-to-edge repair”, effectively reducing the leak by bringing the valve leaflets closer together.
This technique offers the advantages of less pain, shorter hospital stay, and quicker recovery compared to traditional surgical repair.
Why is it performed?
A mitral valve clip is typically recommended for patients with moderate to severe mitral regurgitation who are not suitable candidates for open-heart surgery due to age, frailty, or other medical conditions. Common symptoms of mitral regurgitation include:
- Fatigue
- Swollen ankles or legs
- Palpitations
- Chest pain
- Breathlessness
Without treatment, mitral regurgitation can worsen over time, increasing the risk of heart failure and arrhythmias.
The procedure
The procedure is performed under general anaesthesia. A catheter is inserted into a leg vein in the groin and carefully advanced to the heart. Using specialised X-ray and ultrasound imaging, the clip is guided to the mitral valve. Once in position, it is closed on the leaking section to reduce the backflow of blood. The procedure typically takes two to four hours.
Recovery
Recovery time varies between patients. Some may be able to return home within 24 to 48 hours, while others may stay slightly longer depending on their overall condition. Many patients experience immediate symptom relief. Before discharge, a comprehensive recovery and follow-up plan will be provided, including guidance on medications, physical activity, and monitoring.
