Vascular anomalies and interventions

In simple complete transposition with atrial septal defect and patent ductus arteriosus, there is pressure and volume hypertrophy of the right atrium and ventricle, and volume and, in some cases, pressure hypertrophy of the left atrium and left ventricle. When there is a ventricular septal defect in addition, there is greater hypertrophy and enlargement of the left ventricle due to increased pressure and volume work of this chamber. When there is pulmonary stenosis in addition to the ventricular septal defect, then the left ventricle reveals only pressure hypertrophy and its size is distinctly smaller than in cases without pulmonary stenosis. Thus, the quantitative anatomic data of simple complete transposition correlate well with the known hemodynamic findings in this condition. Of the various types of shunting defects, it appears that a large atrial septal defect with or without patent ductus arteriosus is the ideal accompanying anomaly.
