Key result
Anterior mitral leaflet reconstruction shows no deaths or reoperations with ~95% in NYHA class I-II.
Why the study?
Does reconstructive mitral valve surgery involving the anterior mitral leaflet result in favorable clinical and echocardiographic outcomes in patients with mitral regurgitation?
Observational (n=20)
Does reconstructive mitral valve surgery involving the anterior mitral leaflet result in favorable clinical and echocardiographic outcomes in patients with mitral regurgitation?
Reconstructive surgery of the anterior mitral leaflet is feasible and safe, resulting in excellent functional status and no reoperations at mid-term follow-up.
Anterior leaflet repair may be feasible with good mid-term outcomes; leaves open durability, generalizability, and need for randomized data.
BACKGROUND: Repair rather than replacement of the diseased mitral valve has been the goal of the cardiac surgeon. Although well accepted for posterior leaflet pathology, a diseased anterior leaflet was believed by some to be irreparable. AIMS: To assess the result of reconstructive mitral valve surgery involving the anterior mitral leaflet in a selected group of patients. METHODS: Twenty consecutive patients with degenerative (19), ischaemic (one) and congenital/calcific mitral regurgitation were evaluated. There were five females and 15 males with a mean age of 62 +/- 12 years (41-75 years). The technique used to repair these valves included chordal transposition, leaflet plication commissuroplasty and a new technique we call leaflet repositioning. RESULT: There were no deaths, follow-up is complete with mean follow-up of 31 +/- five months (two-102) months. All patients have had 2DE and 13 TOE as well. There have been no reoperations due to failure of the repair, 95% of patients are in NYHA Class I-II post operative, while 15% have significant residual regurgitation.

Alvarez et al. (1993) conducted an observational in Mitral regurgitation (n=20). Reconstructive mitral valve surgery involving the anterior mitral leaflet was evaluated on Death and reoperation due to failure of repair. Reconstructive surgery of the anterior mitral leaflet resulted in no deaths or reoperations at a mean follow-up of 31 months, with 95% of patients in NYHA Class I-II.
