Right Ventricular Inflow Obstruction Caused by Supratricuspid Ring after the Conventional Biventricular Repair of Congenitally Corrected Transposition of Great Arteries - A case report -.

A seventeen-month-old male baby, who had received conventional biventricular repair for congenitally corrected transposition of the great arteries, underwent excision of supratricuspid ring. Although tricuspid valve annulus was marginally small on direct inspection in the operating theater, circumferential excision of supratricuspid ring alone completely relieved the right ventricular inflow obstruction.
