Right ventricular infarction results from occlusion of the right coronary artery proximal to the marginal branches that perfuse the anterior wall of the right ventricle. 1 , 2 However, the anterior free wall of the right ventricle is involved less frequently than the posterior wall in patients with inferior myocardial infarction. 1 , 3 , 4 Furthermore, right ventricular infarction occurs less often than would be expected on the basis of the frequency of proximal occlusion of the right coronary artery. 5 , 6 The explanations for the pathological findings and for the relative infrequency of right ventricular infarction are uncertain. Recent studies suggest that patients with . . .
