ST elevation in the anterior precordial leads during right ventricular infarction: Lessons learned during primary coronary angioplasty - A case report

ST elevation in the anterior leads may be due to isolated right ventricular infarction associated with occlusion of a nondominant or codominant right coronary artery. The authors report a case of isolated right ventricular in farction from a dominant right coronary artery's proximal occlusion in the presence of collateral circulation provided by the left coronary artery. Ex tensive damage occurred owing to compromise of the collateral circulation d uring primary coronary angioplasty. This is an unusual angiographic pattern for isolated right ventricular infarction. The potential consequences of p ercutaneous interventions to collateral vessels is discussed.
