An isolated right ventricular myocardial infarction and severe tricuspid regurgitation due to occlusion of a non-dominant right coronary artery: role of delayed revascularization

Isolated right ventricular myocardial infarction (IRVMI) results from atherothrombotic disease of acute marginal arteries or a non-dominant right coronary artery (RCA) and normal coronary arteries in the presence of right ventricle (RV) hypertrophy (1-4). Although it is rarely manifests, an IRVMI might have dramatically consequences such as dilatation of RV, severe tricuspid regurgitation, pulmonary embolization, severe bradycardia, RV free wall rupture, cardiogenic shock, ventricular tachyarrhythmia and sudden death. In this paper, we discussed the role of delayed percutaneous coronary intervention (PCI) in the treatment of a complicated IRVMI due to occlusion of a non-dominant RCA.
