Surgical correction of the subvalvular apparatus to reduce tethering, along with mitral annuloplasty, has recently been highlighted in the treatment of functional mitral regurgitation. However, because of anatomical differences in the subvalvular apparatus between cases of progressive cardiomyopathy, a uniform procedure to reduce tethering has not been established. We report a case-specific reconstructive method consisting of procedures mainly on papillary muscles for a rare case of dilated-phase hypertrophic cardiomyopathy with moderately severe mitral regurgitation.
对于功能性二尖瓣反流的治疗，最近强调了对瓣下结构进行手术矫正以减少牵拉，并联合二尖瓣环成形术。然而，由于进行性心肌病病例中瓣下结构存在解剖差异，尚未确立一种统一的减少牵拉的手术方法。我们报告了一种针对特定病例的重建方法，该方法主要针对乳头肌进行手术，用于治疗一例罕见的处于扩张期的肥厚型心肌病合并中度严重二尖瓣反流的病例。
