Abstract

We present the case of a 50 year-old woman with known anomalous origin of left circumflex coronary artery from the right sinus of Valsalva, with retro-aortic course confirmed by coronary computed tomography angiography. Due to progressive dyspnoea and a suspicion of ischaemia, the patient was referred to the Nuclear Medicine department for stress-rest myocardial perfusion scintigraphy. The imaging revealed inducible perfusion deficits mainly in the lateral and infero-lateral walls involving 14% of the total left ventricular (LV) myocardium. Although the detected coronary anomaly is considered nonmalignant, the extent of inducible ischaemia exceeding 10% of the LV myocardium should be taken into consideration while managing the patient.
