title: Supravalvular stenotic mitral ring with ventricular septal defect.
abstract: BACKGROUND
  Supravalvular mitral ring is exceedingly uncommon.
  
  
  METHODS
  We report a 4-year-old girl with supravalvular stenotic mitral ring and ventricular septal defect (VSD). The VSD was closed by a Dacron patch and the supravalvular ring was excised. For treatment of supravalvular mitral ring with obstruction, surgical resection is commonly performed.
  
  
  RESULTS
  There are no reports of long-term follow-up after resecting the supravalvular mitral ring.
  
  
  CONCLUSIONS
  In our case, no mitral stenosis was evident on postoperative echocardiogram performed 3 years after surgery.
