We present the case of a 26 year-old man who presented to hospital with monomorphic ventricular tachycardia (VT) at a rate of 170bpm after exercising on a treadmill. Multimodality imaging with transthoracic echocardiogram (TTE), cardiac magnetic resonance imaging (CMRI) and computed tomography coronary angiogram (CTCA) demonstrated two causes for ventricular tachycardia; hypertrophic cardiomyopathy (HCM) and an anomalous right coronary artery (RCA) arising from the left coronary sinus, with a potentially malignant interarterial course. Both conditions can be associated with sudden cardiac death (SCD). We discuss the management dilemmas in this unique patient.
