<prompt> Eisenmenger syndrome is characterized by all exceptReturn of left ventricle right ventricle to normal sizePulmonary veins not distendedPruning of peripheral pulmonary arteriesDilatation of central pulmonary arteries  <response>: Eisenmenger syndrome is associated with severe pulmonary arterial hypertension and right ventricular hypertrophy.The right ventricular size will certainly not return to normal once eisenminger syndrome develops.Chest X-ray in Eisenmenger syndromeDilated and prominent central arteries.Rapid tapering pruning of the peripheral pulmonary vasculature.The hilar central area suggests pulmonary plethora whereas the peripheral lung fields suggest pulmonary oligemia.Clinical manifestations of Eisenmenger syndromeSymptoms -- Cyanosis Differential cynosis in PDA, fatigue, effort intolerance and dyspnea.Physical examinationCyanosis and clubbing Parasternal impulse more in ASDPalpable P2 Wide and fixed splitting of S2 in ASDPulmonary regurgitation murmur. Normal splitting of S2 in PDAEjection systolic murmur pulmonic. o Single S, or paradoxical splitting in VSD ECGRight ventricular hypertrophy with right axis deviation.P pulmonale.
