Purpose

  1. Background
  • Mitral valve (MV) repair: Widely regarded as the procedure of choice for significant degenerative mitral regurgitation (MR) requiring surgery1
  • Late recurrence of valvular dysfunction:  Great risk in rheumatic heart disease, mixed mitral stenosis (MS) and MR
  • In non-rheumatic disease: Recurrent MR (m/c cause of failure)
  • MS (rare): Pannus overgrowth from the annuloplasty ring (Fig. 1)

    → Small mitral annuloplasty rings, Type of ring annuloplasty (Flexible (Duran) ring > rigid (Carpentier-Edwards) ring)2-4 

 

 

    2. Purpose

  • This study investigated computed tomographic (CT) appearance after mitral ring annuloplasty, especially comparing CT findings between patients with normal pressure gradient (PG) and patients with functional MS and between 2 commonly used types of annuloplasty ring.
