A New Method Utilizing Indicator-Dilution Technics for Estimation of Left-to-Right Shunts in Infants

A new method utilizing indicator-dilution technics for estimation of left-to-right shunts in infants.

Earpiece dye-dilution technics for estimation of the left-to-right shunt in infants and children.

The infants and children subjected to this study consisted of 21 cases with ventricular septal defect, 9 cases with atrial septal defect, 3 cases with patent ductus arteriosus, one case with partial anomalous pulmonary venous return and 3 cases with the innocent murmurs (cf. Tables 1 and 2). The right-heart catheterization was performed in all the cases according to the conventional Fick proced...

A simplified method for quantitating left-to-right shunts from arterial dilution curves.

This report presents a new, simple and reliable method of quantitating left-to-right shunts from arterial dilution surves. When indicatior (e,g., indocyanine green) is injected centrally (right venticle or pulmonary artery) and blood is withdrawn rapidly from either the aorta or other central systemic artery, in the presence of a left-to-right shunt to recorded indicator-dilution curve usually ...

Left-to-Right Shunts

Contrary to the opinion of French pediatrician HenriLouis that isolated ventricular septal defects (VSDs) are universally well tolerated, the subsequent discoveries of Eisenmenger, Abbott, Wood, and others have taught us that the prognosis of left-to-right shunt lesions is not always benign. After more than a century of research, as pediatric cardiologists and congenital heart surgeons, we clai...
