New surgical procedure for ischemic/functional mitral regurgitation: mitral complex remodeling.
Although numerous surgical techniques have been developed for ischemic/functional mitral regurgitation, none has clearly improved patient outcome. We report the clinical application of a new mitral complex remodeling procedure for ischemic/functional mitral regurgitation that allows comprehensive remodeling of the entire mitral complex. The mitral complex remodeling procedure consists of three major concepts: division and reconstruction of secondary chords, undersized annuloplasty, and bilateral papillary muscle relocation.
