Abstract
Another approach for the localization of left-to-right intracardiac shunts has been described. RIHSA was injected through the tip orifice of a double-lumen catheter as continuous samples of blood were being obtained from the proximal lumen of the catheter and from the brachial artery simultaneously. Radioactive counting rates of the two samples were continuously recorded for calculation by the pip interval method. The catheter sampling sites were selected to demonstrate the specific location at which indicator appeared earlier than at the brachial artery. Seven of the patients in this study had atrial septal defects. One patient had a ventricular septal defect. Verification of the RIHSA localization of the defect was done in all patients by blood oxygen and pressure studies and in four patients at surgery. © 1959.
