[Treatment of complicated forms of mitral valve stenosis by the method of balloon dilatation].

The degree of the anatomical changes of the valvular apparatus and the severity of the hemodynamic disorders affect the results of radiologically-guided intravascular treatment of mitral stenosis. The complicated forms of mitral stenosis included cases of multivalvular affections (52), calcinosis (61), coarse fibrosis (119), pulmonary hypertension (91), atriomegaly (79), aortic incompetence exceeding I degree (37), and anomalies in patients over 50 years of age (77). The listed conditions were an additional risk factor in performing 221 interventions for percutaneous catheter-balloon valvuloplasty. They call for individual alteration of the techniques of balloon dilatation and dosed manipulation on the valvular structures in accordance with the concrete form of the valvular disease. Such an approach made it possible to reduce the frequency of complications (from 30 to 4.8%) and mortality (from 9.6 to 0.59%).
