Single coronary artery with origin of right coronary artery from left circumflex in a patient with ventricular tachycardia: a case report

Only a few cases of a single coronary artery (CA) have been described. Almost all cases reported so far also had associated atherosclerotic coronary artery or valvular heart disease. We present a 48 years old male with atypical chest pain with an episode of Ventricular Tachycardia (VT) on treadmill test (TMT). Coronary angiography (CAG) showed a single Left coronary artery (LCA) with Right coronary artery (RCA) arising from left circumflex artery (LCX) without any atherosclerotic disease
