[Comparative evaluation of the dynamics of the echocardiographic parameters following open and closed mitral commissurotomy].

A comparative study of early post-operative changes in a number of echocardiographic parameters was carried out in patients with pure and prevailing mitral stenosis following an open (24 patients) and closed (32 patients) mitral commissurotomy. The increment in the rate of early diastolic fall of the anterior mitral cusp, and total valve excursion, as well as reverse dynamics of the maximum left-atrial anteroposterior size were shown to differ significantly in post-open-commissurotomy patients from the corresponding parameters observed following the closed-technique operation. Mitral stenosis correction under visual control was associated with more effective as well as more radical results.
