Overview
Eisenmenger's syndrome or Eisenmenger's reaction is defined as the process in which a left-to-right shunt in the heart causes increased flow through the pulmonary vasculature, which leads to pulmonary hypertension, which finally causes increased pressures in the right side of the heart and reversal of the shunt into a right-to-left shunt. This right to left shunt causes the patient to become cyanotic. Thus, Eisenmenger's syndrome is said to develop when there is a pulmonary artery disease, right-to-left heart shunting and cyanosis
