Mital valve regurgitation with anterior mitral leaflet chordal rupture or elongation —Repair using the flip over technique—

  • 21 Accesses

Abstract

Repair of prolapsed anterior mitral leaflet has remained technically difficult. The purpose of this study was to assess the clinical results after using the flip-over technique for patients with anterior mitral leaflet prolapse due to dhordal rupture or elongation. Between January 1993 and September 1997, fifteen adult patients with pure mitral valve regurgitation (MR) due to prolapse of the anterior mitral leaflet underwent repair using the flip-over technique. The indication for this procedure were; 1) all mitral structures except the prolapsed area must appear to be intact, and 2) the corresponding chordae attached to the posterior leaflet should be sufficiently strong to be transferred to the anterior leaflet. The prognoses following this technique were retrospectively studied to assess the early and mid-term clinical outcome of this procedure. Follow up was complete in all patients and ranged from 2 to 56 months (with a mean of 25 ± 17.9 months). There was no hospital death, None required reoperation. One patient died because of acute recurrent MR during follow-up. No other complication was experienced. Doppler echocardiographic studies at the final follow-up showed less than mild regurgitation in 11 (78.6%) of the 14 surviving patients. We believe that this procedure was effective for that the obtained repair of a prolapsed anterior mitral valve and early and mid-term clinical outcome from this procedure has been satisfactory.
