原始语种摘要: The long-term outcomes of undersizing annuloplasty for the treatment of ischemic mitral regurgitation (IMR) is affected by the progressive dilation of the annulus, which carries increased risk for ring disinsertion. Reasons underlying this phenomenon might be found in the excess of physical stress on the annuloplasty sutures during the ventricular remodeling process. We report a technique based on the placement of a double row of overlapping sutures aiming at reducing the potential for ring disinsertion. Eleven patients with IMR undergoing mitral valve repair associated with coronary bypass grafting were treated with this technique and echocardiographically followed up at 6 and 12 months. The overall annular dimension decreased significantly with a significant reduction of the tenting...
