[Clinical diagnosis and prognosis of the course of congenital heart defects with pulmonary stenosis].

An analysis of 433 observations is presented (164 cases of isolated pulmonary stenosis, 132 cases of its combination with atrial septal defect, and 137--with ventricular septal defect), the patients being 1 year 1 month to 36 years old, and the form of their heart disease being verified during surgery on a "dry" heart. The mentioned diseases were classified into 3 groups according to the tactical importance of the pulmonary stenosis. Haemodynamic studies in patients with pulmonary stenosis and an intact ventricular septum have demonstrated that with age right-ventricular hypertension progresses the faster the greater the pulmonary artery valve is stenosed. A combination of a valvular stenosis with a large ventricular communication is accompanied by a levelling of the pressure in both ventricles, its absolute figures being somewhat higher in patients over 16 years of age.
