Angiocardiographic findings and morphogenesis of criss-cross heart with situs solitus, concordant artrioventricular relationships and L-transposition.
A case of so-called criss-cross heart is presented. The right atrium drained to the left-sided morphologic right ventricle from which the aorta originated anteriorly and leftward. The left atrium drained to the right-sided morphologic left ventricle, from which the pulmonary artey originated posteriorly and rightward. These angiographic findings are morphogenetically interpreted as a clockwise rotation of approximate 90 degrees looking toward the base (from the inferior view) of d-bulboventricular loop following the truncal septation.
