Eisenmenger syndrome is characterized by all except:

Answer is A (Return of left ventricle and right ventricle to normal size) Eisenminger syndrome is associated with severe pulmonary aerial hypeension and right ventricular hyperophy. The right ventricular size will ceainly not return to normal once eisenminger syndrome develops. Dilated central pulmonary aeries and rapid tapering of the peripheral pulmonary vasculature (pruning) are the radiographic hallmarks of Eisenminger's syndrome' - Braunwald. 'The hilar (central) area suggests pulmonary plethora whereas the peripheral lung fields suggets pulmonary oligemia' - Ghai 6th/415 'Pulmonary hypeension develops due to pulmonary vascular obstructive disease affecting the 'pulmonary aeries'. 'Pulmonary vein' will not be distended.
