Abstract

The short circulatory pathways of infants cause rapid systemic and pulmonary circulation times. So rapid are they that the usual methods for calculating left-to-right shunts frequently yield a considerable overestimation. A new formula was described for use with injections into the left heart and arterial sampling. This formula applied to 11 infants and 7 older patients showed a significantly better correlation with oximetric calculations than did the right heart injections. This method also will reveal the presence of a left-to-right shunt that is of insufficient magnitude to distort dye curves obtained following right heart injections.
