title: Pulmonary systemic flow ratios in atrial septal defect assessed by ventricular volume measurements.
abstract: Twenty-eight patients with isolated secundum atrial septal defects were examined with right and left heart catheterization and cardioangiography. The radiographically assessed pulmonary-systemic stroke volume ratios and the physiologically determined pulmonary-systemic flow ratios correlated well. However, some striking discrepancies were observed the possible causes of which are discussed.
