A Simplified Indicator-Dilution Technic for the Localization of Left-to-Right Circulatory Shunts

A Simplified indicator-dilution technic for the localization of left-to-right circulatory shunts. An experimental and clinical study of intravenous injection with right heart sampling.

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

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 When indicatior (e,g., indocyanine green) is injected centrally (right venticle or pulmonary artery) and blood is withdrawn rapidly from either the aorta or other central systemic artery, in the presence of a left-to-right shunt to recorded indicator-dilution curve usually ...

Hyperventilation test for diagnosis of left-to-right circulatory shunts.

Pulmonary and systemic arterial carbon dioxide tensions (Pco2) were measured at cardiac catheterization in I.f patients with left-to-right circulatory shunts and in irS patients with valvular heart disease. The measurements were performed under resting conditions and at 5-sec intervals during a 30-sec period of hyperventilation. In both groups the systemic arterial Pco2 fell significantly durin...
