Why the study?
Does precordial counting with iodine-131 labelled albumin or technetium-99m accurately detect left-to-right intracardiac shunts compared to cardiac catheterization?
Population
Patients with rheumatic or congenital heart disease, and normal subjects.
Comparison

Tc-99m precordial counting may support preliminary non-invasive shunt detection; leaves open validation against contemporary imaging in heart failure.
Does precordial counting with iodine-131 labelled albumin or technetium-99m accurately detect left-to-right intracardiac shunts compared to cardiac catheterization?
Precordial counting with technetium-99m is a useful preliminary non-invasive investigation for detecting left-to-right intracardiac shunts.
Lorimer et al. (1969) studied this question.
