    Comments:
    The patient is cyanosed and of the diseases described only tricuspid atresia is associated with cyanosis. Other causes are Fallot’s tetralogy, single ventricle and Transposition of the great vessels. Eisenmenger’s syndrome develops with the switch to right to left flow associated with deteriorating VSD etc.
