Reductive annuloplasty of double orifices in patients with primary dilated cardiomyopathy.
BACKGROUND
Patients with primary dilated cardiomyopathy exhibit extensive remodeling of the left ventricle, mitral and tricuspid annular dilation and both mitral and tricuspid regurgitation. These factors significantly contribute to heart failure, and are predictors of early lethal outcome. The aim of this study is to show hemodynamic and clinical improvement after reductive annuloplasty of both mitral and tricuspid orifices in primary dilated cardiomyopathy.


METHODS
There were 76 patients with primary dilated cardiomyopathy. Mitral annuloplasty using a Carpentier-Edwards sizer was performed on 9 patients, and posterior semicircular reductive annuloplasty was performed on 67 patients. Modified De Vega's tricuspid annuloplasty was performed on all patients.


RESULTS
Immediate and long-term results showed significant improvement in hemodynamic values and myocardial contractility after operation.


CONCLUSIONS
Reductive annuloplasty of both mitral and tricuspid orifices corrects remodeling of the left ventricle of the heart, changes sphericity and geometry of the left ventricle, improves hemodynamic action of the left and right ventricle, and slows down progression of heart failure. We recommend reductive annuloplasty of both mitral and tricuspid orifices before or soon after the first decompensation.
