A Comparative Study between First-Pass Nuclear Angiography and Cardiac Catheterization in the Detection and Quantitation of Left-to-Right Shunts in Congenital Heart Disease
Accurate quantification of left-to-right shunt requires oximetric measurement or dye-dilution study during cardiac catheterization. First-pass nuclear angiocardiography (FPNA) was applied in detecting the left-to-right shunt. This method is a rapid noninvasive procedure that yields accurate and reproducible measurement of left-to-right shunts. The purpose of this study is to compare the size of left-to-right shunt by using FPNA and the oximetric method during cardiac catheterization in children.
