Acute myocardial infarction in a patient with anomalous origin of the right coronary artery: depiction at whole-heart coronary magnetic resonance angiography and delayed-enhanced imaging
Abstract
A 71-year-old man was admitted to our hospital because of anterior chest pain. His electrocardiogram showed ST-segment depression and cardiac enzymes were normal. Non-ST-elevation acute myocardial infarction was suspected and whole-heart magnetic resonance imaging was performed. Whole-heart coronary magnetic resonance angiography (MRA) showed an anomalous origin of the right coronary artery from the left sinus of Valsalva and delayed-enhanced imaging showed transmural hyperenhancement of the inferior wall. Coronary angiography revealed the anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva and occlusion in the proximal portion of the RCA. Coronary revascularization was achieved by intracoronary thrombolysis followed by stent implantation. Whole-heart coronary MRA and delayed-enhanced imaging allows simultaneous assessment of coronary artery anomaly and extent of myocardial infarction.
