title: Intermittent stuck valve after aortic valve replacement with a mechanical valve: A case report.
abstract: BACKGROUND
  Intermittent stuck valve after mechanical valve replacement surgery is a very rare and severe complication.
  
  
  METHODS
  We present 1 case of a 53-year-old woman after aortic valve replacement for severe aortic valve stenosis combined with hypertrophy septum. She was diagnosed with intermittent stuck valve only 1 day after surgery by clinical symptoms, intraoperative transoesophageal echocardiogram, and intraoperative findings.
  
  
  CONCLUSIONS
  Although indications for concomitant myectomy during aortic valve replacement are not clear, we recommend myectomy to prevent stuck valve after St Jude Medical Regent prosthesis replacement for severe aortic valve stenosis combined with hypertrophy septum.
