Key result
Mitral plication annuloplasty using a semicircular buttressed suture resulted in 3% in-hospital mortality, 4.8% late mortality, and a 6.6% rate of mitral valve replacement over a mean 22.8 months.
Why the study?
Does mitral plication annuloplasty with a semicircular buttressed suture provide acceptable clinical and echocardiographic outcomes in patients with mitral valve disease?

Does mitral plication annuloplasty with a semicircular buttressed suture provide acceptable clinical and echocardiographic outcomes in patients with mitral valve disease?
Mitral plication annuloplasty using a buttressed suture demonstrates acceptable mid-term outcomes and may serve as an inexpensive alternative to ring implantation.
Hypothesis-generating for this low-cost technique; randomized trials needed before practice change.
We present five years' experience with mitral plication annuloplasty, performed with a semicircular buttressed suture around the posterior leaflet in 130 patients (mean age 58 +/- 11 years) with primary mitral valve disease (n = 71) or functional mitral regurgitation (n = 59). In 65 cases the mitral valve itself was also repaired. Concomitant myocardial revascularization was performed in 40 cases and aortic valve replacement in 43. All but three patients were followed up (97.6%). Postoperative echocardiography showed acceptable mitral area (2.28 +/- 0.39 cm2) and good valve competence in all cases. Inhospital mortality was 3% and late mortality 4.8%. During the follow-up period (22.8 +/- 10.9 months) 8 patients (6.6%) required mitral valve replacement because of progression of native valve disease (n = 4), technical failure (2) or expansion of the annuloplasty suture (2). Mitral annuloplasty thus can be performed simply and with good results, using a strong, non-stretchable buttressed suture. This procedure can be an inexpensive alternative to ring implantation.

Annamaria Bodi Zsolt L. Nagy (2000) conducted an observational in Primary mitral valve disease or functional mitral regurgitation (n=130). Mitral plication annuloplasty with a semicircular buttressed suture was evaluated. Mitral plication annuloplasty using a semicircular buttressed suture resulted in 3% in-hospital mortality, 4.8% late mortality, and a 6.6% rate of mitral valve replacement over a mean 22.8 months.
