Figure 1

Male, soccer player. LBBB with left axis deviation discovered by chance at the age of 19 years. An ECG performed 2 years earlier was normal. The echocardiogram was normal. CT coronary angiography (performed at the age of 22 years) shows the left circumflex (CX) artery arising from the right coronary sinus, close to the right coronary artery (RCA). The CX runs back to the aorta.
