| Popis: | 1.1. A series of cases exhibiting the combination of pulmonary stenosis and a defect permitting a left to right shunt is described. The series includes examples of the combination of pulmonary stenosis with atrial septal defect, transposed pulmonary veins and ventricular septal defect, respectively. 2.2. The clinical features of the cases were in general those of mild or moderate pulmonary stenosis. It is thought that electrocardiographic and radiologic findings may suggest the presence of an accompanying septal defect. 3.3. Atrial septal defect with left to right shunt occurred in the presence of mild or moderate pulmonary stenosis and a normal left to right atrial pressure gradient. These findings are contrasted with those in pulmonary stenosis with right to left shunts. 4.4. A shunt through transposed pulmonary veins may occur in the presence of severe pulmonary stenosis. 5.5. Cases of ventricular septal defect and pulmonary stenosis appeared to fall into two groups; those with slight to moderate elevation of right ventricular pressure and those in which the right ventricular and systemic pressures were similar. 6.6. The surgical implications of these combined lesions are discussed. |
