Coronary artery anomalies (CAAs) are present in 1-1.96% of the population [1,2]. The clinical significance of single CAAs differs depending on the course of the artery. Those that take an inter-arterial (malignant) course, between the aorta and pulmonary artery, can present with syncope or sudden death [1,3]. This is attributed to the myocardial ischaemia that ensues when the single coronary artery is compressed between high-flow structures in systole. Whereas, those that traverse benign, inter-ventricular paths do not predispose to myocardial ischaemia, hence, patients are often asymptomatic [1,3]

Case presentation: A 22 year old male with a 3-year history of impaired left ventricular function and a past medical history of anthracycline-treated acute myeloid leukaemia was admitted with symptoms of worsening cardiac failure. The patient’s symptoms progressed over 3 months, and included diminished exercise tolerance, orthopnoea, paroxysmal nocturnal dyspnoea, nausea, abdominal pain and diarrhoea. He also described an acute nocturnal episode of severe chest pain, shortness of breath, and involuntary twitching, beginning in the left hand and progressing proximally. The patient was diagnosed with dilated cardiomyopathy - a well-documented side effect of anthracycline therapy.
