[Prognosis of the results of closed mitral commissurotomy based on data of preoperative M-echocardiographic assessment of the state of the mitral valve].
A favourable result of closed mitral commissurotomy was prognosticated in patients with "pure" mitral stenosis, with no radiological signs of valve calcinosis, according to the findings of M-echocardiography. The first stage of prognostication is selection of patients with structural affection of the cusps rated no higher than 4 marks and of the chordae--no more than 2 marks. The second stage is analysis of the functional signs: amplitude of diastolic movement of the anterior cusp of the mitral valve, the rate of its opening and closure, and relative value of septal-cuspal separation. The third stage--determination of the type of prognosis (authentic, doubtful, negative) according to the gradation of the obtained values of the functional echocardiographic signs.
