[Feasibility of echocardiography in evaluation of hemodynamic disorders in patients with interatrial septal defects]

Changes in heart cavities were examined echocardiographically in 71 patients with various forms of defective interatrial septum. Echocardiographic findings were correlated with heart cavity catheterization data in 64 cases and verified at surgery in 46. Criteria have been established for the assessment of arterial--venous blood discharge in relation to the changes in heart cavity size.
