What is Percutaneous Mitral Valve Repair?
Percutaneous Mitral Valve Repair (MVR) is a minimally invasive technique employed for treating mitral regurgitation (MR). 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. MR condition is usually seen in adults and elderly people, due to degeneration of the valves that may occur with age or due to genetic influence.
MR is treated either by mitral valve repair or replacement surgery. Percutaneous mitral valve repair also referred to as Mitraclip procedure, is usually employed for treating MR.
The percutaneous mitral valve repair is an edge-to-edge repair technique, based on the surgical Alfieri technique in which the posterior and anterior leaflets are joined with a suture, creating double-orifice mitral valve. The technique is most appropriate for treating degenerative as well as functional mitral regurgitation.
- A steerable guide catheter
- A clip delivery system
- The MitralClip device (implant)
Procedure of Percutaneous Mitral Valve Repair
- The patient is laid on the operation table and is anesthetized
- A specially-designed steerable, guiding catheter is advanced through the femoral vein across the inter-atrial septum into the left atrium; under transoesophageal echo (TEE) and fluoroscopic imaging guidance
- A metal implant, the MitraClip device, is attached to the end of a steerable clip delivery system
- MitraClip device is advanced through the guide catheter and positioned in the LA or left atrium at the place of the leakage
- The clip is pointed perpendicular to the line of the mitral leaflet and then moved on across the valve into the left ventricle
- MitralClip device grips the leaflets and is closed to create a competent double orifice valve
