Ventricular inversion associated with normally related great vessels.

A patient with ventricular inversion with normally related great vessels and double inlet left ventricle is presented. the patient also showed features of Down's syndrome. Association of ventricular inversion with normally related great vessels is rare and leads to a basic functional state like that of complete transposition of great vessels derived from the connections between the ventricles and great vessels. The association of ventricular inversion with Down's syndrome observed in the case reported represents a rarity.
