[Isolated mitral stenosis: systolic and diastolic dynamic geometry of the left ventricle. Integration with several hemodynamic parametres (author's transl)].

75 patients with isolated mitral stenosis were studied. Particular attention was paid to the integration of the parametres VTD, FE, mitral area, pulmonary artery pressure and dynamic systolic and diastolic geometry of the left ventricle. The existence of isolated MS with alteration of the left ventricular function not depending on the alterations of the preload and the forms with raised FE, was demonstrated. A classification into 6 groups was made, each characterized by special geometric modalities of contraction and relaxation. A significant compensation of several of the parametres of systolic mecanism (hyperkinesia) and diastolic (SERP) dynamic geometry was observed. It was therefore concluded that a more precise definition of the interaction of ventricular function with left atrial function is necessary.
