[Reoperation in mitral valve reconstructive surgery].
In the past few years reconstructive surgery of the mitral valve has experienced a growing popularity. It is now clearly established that restoration of a normal function valve is preferable to valve replacement. The authors report the results of the mitral valve reconstructive surgery in a population of 701 patients with high incidence of restrictive lesions of rheumatic fever. This represents an experience of 14 years. 5.1% of patients who underwent mitral valvuloplasty required late reoperation for recurrent mitral valve dysfunction. Repeat mitral valve repair resulted in successful treatment for 40% of these patients.


CONCLUSIONS
The mitral valve repair failure are: 1--Procedure related: (58.1%); a--surgical technical related--35.8%; b--no ring implantation (in restrictive lesions)--15%; c-rupture of previously chordae shortened--7.4%. 2--Valve related: (41.9%); a--progressive primary valve disease--(25.4%); b--wrong surgical indication--(15%); c--endocarditis--(1.5%).
