Isolated right ventricular infarction: a rare complication of coronary artery dissection.
Infarction of the right ventricle generally occurs in association with posterior left ventricular infarction, and isolated right ventricular infarction is unusual. We have reported a case of acute infarction of the right ventricle unassociated with infarction of the left ventricle in a patient with type I aortic dissection that extended into the right coronary artery, resulting in near-complete occlusion of its lumen. We believe that poor collateral circulation of the myocardium played a major role in the pathogenesis of isolated right ventricular infarction after sudden occlusion of the right coronary artery.
