Concordant Ventriculoarterial Connections With Abnormally Related Arterial Trunks (Anatomically Corrected Malposition) Associated With Right Ventricular Outflow Tract Obstruction by Accessory Valvar Tissue.

Anatomically corrected malposition of the great arteries is a rare conotruncal anomaly that is often confused with congenitally corrected transposition of the great arteries. This case report describes the successful surgical management of an adolescent with severe right ventricular outflow obstruction caused by accessory tricuspid valve tissue in the presence of situs inversus with atrioventricular and ventriculoarterial concordance with malposed great arteries (anatomically corrected malposition) {I,L,D}.
