[Dynamics of the functional state of the oxygen transport system following surgical correction of mitral valve stenosis].

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.

[Spontaneous contrast of the left atrium in mitral valve stenosis].

The left atrial spontaneous contrast is uncommon finding during transthoracic échocardiography. Transesophageal echocardiography provides superior imaging of the left atrium and left spontaneous contrast has been detected more frequently by this technique in rheumatic mitral stenosis. In order to analyze the significance of spontaneous contrast, we have studied 100 patients with mitral stenosis. Trans thoracic and transesophageal echocardiography were performed in all patients. Left atrial spontaneous echo contrast was detected in 60 patients (group A) and was absent in 40 patients (group B) The mean of mitral valvular area was 0.9 10.2 mm in group A and 48 9.5 mm in group B (p < 0.001). Ther was a high incidence of atrial fibrillation in group A; 63% VS 12% in group B (p < 0.001). A systemic embolization was noted in 20% of patients in group A; No one of group B has presented this complication (p < 0.001).
