Spatial Distribution of Right Ventricular Perfusion Abnormalities Following Acute Right Coronary Artery Occlusion: A Study by Myocardial Contrast Echocardiography and Blue Dye Staining

Abstract

RV perfusion abnormalities produced by RCA occlusion are larger in the basal than apical level of the RV free wall. This finding elucidates the spatial distribution of the territory of the RCA on the RV free wall, and may help in identifying and assessing RV ischemia by echocardiography in humans. Moreover, the data in the current study indicate that RV infarction may be produced by occlusion of the coronary arteries except RCA, because the territory of the LAD on the RV free wall is clearly delineated.
