[Segmental contractility and geometry of the left ventricle of patients with isolated lesions of the mitral valve].

Investigations showed that patients with "pure" stenosis of the left atrioventricular orifice as well as those with mitral insufficiency were characterized by left ventricular myocardial dysfunction expressed in a decrease of the index of left ventricular integral function--the ejection fraction and in change of geometry of the left ventricular cavity. Asynergy (hypokinesia) of the anterior wall segments and the posterior basal segment was revealed in patients with "pure" stenosis and "pure" mitral insufficiency. Hypokinesia in patients with primary mitral insufficiency was revealed in the anterior wall only. The above changes in the left ventricular segmental contractility can be regarded as a cause of left ventricular pump function disorder.
