title: Superoinferior ventricles with superior left ventricle and inferior right ventricle: a newly recognized form of congenital heart disease.
abstract: We report the first known case of supero-inferior ventricles with a superior morphologically left ventricle and an inferior morphologically right ventricle. This 2 1/2-year-old boy also had dextrocardia, double-outlet right ventricle [S,L,L], right-sided mitral atresia, left-sided tricuspid regurgitation, a large conoventricular type of ventricular septal defect, and pulmonary outflow tract stenosis. This very rare form of superoinferior ventricles appears to be due to excessive levorotation (approximately equal to 170 degrees) of discordant L-loop ventricles.
