title: Pure right ventricular infarction resulting from coronary ectasia: importance of diagnostic imaging.
abstract: Isolated right ventricular (RV) infarction may occur during percutaneous coronary intervention resulting from selective occlusion of a ventricular branch of the right coronary artery (RCA). We present a case of a pure RV infarction without iatrogenic origin that at the initial electrocardiographic analysis was suggestive of a left anterior descending artery-related acute myocardial infarction. Coronary angiography results made us suspect thrombotic occlusion of a small branch of the ectatic RCA resulting from slow flow. Final diagnosis was confirmed by coronary computed tomographic angiography and cardiac magnetic resonance imaging, underlining the essential diagnostic role of these imaging modalities.
