title: [Dynamics of the functional state of the oxygen transport system following surgical correction of mitral valve stenosis].
abstract: Twenty-one male and 32 female patients were examined, using spiroergometry with simultaneous measurement of maximum oxygen consumption, in a study of natural adaptation after surgical correction of mitral stenosis. It was demonstrated that the transformation in the oxygen transport system after closed mitral commissurotomy continued throughout the first post-operative year and resulted in considerably improved physical working capacity; two phases can apparently be distinguished here: during the first phase, working capacity mostly expands at the expense of improved pump function of the heart, and in the second phase, due to better peripheral circulation in working muscles.
