Medtronic received information that eight years and eleven months post implant of this 28mm mitral annuloplasty ring, the ring was explanted and replaced with a 27mm bioprosthetic valve.The indication for replacement was severe regurgitation and moderate stenosis.Examination of the native mitral valve revealed thickened anterior and posterior leaflets.The posterior leaflet appeared retracted, and the surgeon felt this was contributing to the insufficiency.During the replacement procedure, a trapezoid portion of the anterior leaflet was resected, and the posterior leaflet was retained.Additionally, the native tricuspid valve was repaired with an annuloplasty ring.Post-operative transesophageal echocardiogram (tee) demonstrated mild mitral insufficiency and trivial tricuspid insufficiency.No additional interventions took place, and no additional adverse patient effects were reported. .
