Isolated right ventricular infarction can mimic anteroseptal myocardial infarction on ECG, but can be distinguished by decremental ST-segment elevation in precordial leads (V1 > V2) and concomitant ST elevation in lead III.
Isolated right ventricular infarction (RVI) is an underrecognized clinical entity that often mimics anteroseptal myocardial infarction due to its characteristic ST-segment elevation (STE) in precordial leads. We report the case of a 55-year-old man who presented with acute chest pain and STE in leads V1 and V2. Despite typical anteroseptal infarction patterns, the electrocardiogram (ECG) revealed decremental STE (V1 V2), concomitant STE in lead III, and reciprocal ST depression in lateral leads. Coronary angiography confirmed proximal occlusion of the non-dominant right coronary artery. This case highlights the diagnostic challenges of isolated RVI and underscores key ECG features that distinguish it from anteroseptal infarction. Early recognition is imperative to avoid detrimental therapies (e.g., vasodilators) and to prioritize reperfusion and preload optimization.
He et al. (Fri,) conducted a case report in 55-year-old man with isolated right ventricular infarction due to proximal occlusion of a non-dominant right coronary artery presenting with acute chest pain and ST-segment elevation in leads V1 and V2 (n=1). Thrombus aspiration and reperfusion via percutaneous coronary intervention was evaluated on Resolution of ST-segment elevation and reperfusion (TIMI grade III flow) in isolated right ventricular infarction. Thrombus aspiration and reperfusion successfully restored TIMI grade III flow and normalized ST segments in leads V1 and V2 in a patient with isolated right ventricular infarction due to non-dominant right coronary artery occlusion.
