Abstract

To assess the mixing characteristics of the right ventricle and pulmonary artery, radioiodinated 131I serum albumin and indocyanine green dye were injected simultaneously in 16 subjects. One indicator was injected into the atrium and the other into the ventricle, or both were injected at different sites in the ventricle. Washout curves were obtained by rapid catheter sampling alternately just above or just below the pulmonic valve. The washout of radioisotope was also recorded with a precordial scintillation detection probe.
