Physiologic Pressure Differences between Main and Branch Pulmonary Arteries in Infants By DELORES

SUMMARY Systolic pressure differences of 6 to 45 mm Hg were found between the main and branch pulmonary arteries in 37 of 242 infants undergoing diagnostic cardiac catheter-ization. Eleven of these 37 infants were restudied, and all had lost the pressure difference regardless of the underlying cardiac defect. A similar pressure difference was noted in lambs… CONTINUE READING
