Fig. 10 Single coronary artery (mixed common trunk) in tetralogy of Fallot. A) Right and B) cranially tilted left anterior oblique projections of an antegrade aortogram show a single origin for the coronary arteries. The left main describes an anterior, cranial loop (arrowheads) consistent with a right ventricular free wall course close to the level of the pulmonary annulus. It divides into LAD and CX, which are of modest size.
AO = aorta; CX = circumflex; LAD = left anterior descending; RCA = right coronary artery
