title: Superior left ventricle in combination with inferior right ventricle: presenting with balanced hemodynamics and mild symptoms in a late adolescent.
abstract: We describe a case of superoinferior ventricles with an unusual superior location of the left ventricle and inferior location of the right ventricle. The patient was a 17-year-old boy who had been admitted for paroxysmal supraventricular tachycardia with pre-excitation syndrome. The cardiac anomaly was first recognized after admission, and the pre-excitation syndrome, eventually, was treated successfully by radiofrequency catheter ablation. This case featured a segmental set notation {S, D, S} with concordant atrioventricular and ventriculoarterial alignments. Persistent left superior vena cava was the only associated defect. To the best of our knowledge, there has been only 1 other reported case of superoinferior ventricles in which the left ventricle was in the superior position. In our case, the patient's hemodynamics were sufficiently normal that he had reached adolescence with only minor adverse events.
