Unusual coronary artery pattern in a criss-cross heart

In a case of criss-cross heart with atrioventricular and ventriculoarterial concordance, the right coronary artery and left anterior descending arose from the right hand sinus; the left circumflex originated from the left hand sinus. This pattern existed because of a persistent circle of Vieussens across the right ventricular outflow tract which located superiorly and leftward in such a criss-cross heart.
