Key result
In dogs with intact hearts, Rb 86 clearance was homogeneous in the left ventricle and septum, but generally lower in the right ventricle except at the apex.
Why the study?
Does acute occlusion of the anterior descending or right coronary artery alter the regional distribution of myocardial clearances of Rb 86 in dogs?
Population
Dogs with intact coronary circulation or acute occlusions of the anterior descending or right coronary artery
Comparison
Acute occlusion of the anterior descending or… vs Intact coronary circulation
Design
Preclinical

Baseline Rb-86 clearance map in intact canine hearts may guide perfusion imaging; leaves open whether acute coronary occlusion alters regional distribution.
Does acute occlusion of the anterior descending or right coronary artery alter the regional distribution of myocardial clearances of Rb 86 in dogs?
This preclinical study maps the regional myocardial clearance of Rb 86 in dogs, highlighting baseline differences in perfusion between the left and right ventricles.
Chansky et al. (1962) studied Acute coronary occlusion. Acute occlusions of the anterior descending or right coronary artery vs. Intact coronary circulation was evaluated on Regional distribution of myocardial clearances of Rb 86. In dogs with intact hearts, Rb 86 clearance was homogeneous in the left ventricle and septum, but generally lower in the right ventricle except at the apex.
