It is a non surgical percutaneous technique to correct severe mitral insufficiency in patients at high risk for surgery. This technique applies particularly to patients with dilated cardiomyopathy of every origin with severe impaired contractility of left ventricle and dilated mitral annulus causing mitral insufficiency. The technique requires femoral transvenous approach bringing a catheter in the right atrium. Transeptal puncture is performed in order to reach the left atrium. A guiding catheter is positioned just above the mitral valve annulus, than the clip is inserted into the guiding catheter and pushed below the leaflets of the mitral valve. The clip is than open and grasps the two leaflets in the middle in order to transform the mitral valve in a double orifice valve. The procedure is performed under general anaesthesia under the monitoring of 3Dimension Echocardiogram which is indispensable for the success of this very important procedure.
