Which of the following will be seen in Eisenmenger syndrome, EXCEPT?: (A) Pruning of peripheral pulmonary aeries, (B) Pulmonary veins not distended, (C) Return of left ventricle & right ventricle to normal size, (D) Dilatation of central pulmonary aeries
Answer is C. 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.
