Abstract

We present the case of a patient who presented with palpitations and was found to have atrioventricular re-entrant tachycardia with unusually elevated cardiac biomarkers. A coronary computed tomographic angiography showed a myocardial left anterior descending artery bridge; an accessory pathway was ablated, and cardiac magnetic resonance revealed anteroseptal myocardial infarction resulting from hypoperfusion during tachycardia caused by the left anterior descending artery myocardial bridge. (Level of Difficulty: Intermediate.).

Keywords: CCTA, coronary computed tomographic angiography; CMR, cardiac magnetic resonance; ECG, electrocardiogram; LAD, left anterior descending artery; MR sequences; myocardial infarction; supraventricular arrhythmias.
