Eisenmenger's syndrome (or ES, Eisenmenger's reaction or tardive cyanosis) is defined as the process in which a left to right shunt caused by a congenital heart defect in the fetal heart causes increased flow through the pulmonary vasculature, causing pulmonary hypertension, which in turn causes increased pressures in the right side of the heart and reversal of the shunt into a right-to-left shunt. Eisenmenger syndrome is a cyanotic heart defect characterized by a long-standing intracardiac shunt (caused by ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) that eventually reverses to a right-to-left shunt. This syndrome is less frequent today because of medical screening with echocardiography early in life. Eisenmenger's syndrome can cause serious complications in pregnancy, though successful delivery has been reported. Maternal mortality ranges from 30% to 60%, and may be attributed to fainting spells, thromboembolism, hypovolemia, hemoptysis or preeclampsia. Most deaths occur either during or within the first weeks after delivery.〔Curr Cardiol Rev. 2010 November; 6(4): 363–372.The Adult Patient with Eisenmenger Syndrome: A Medical Update after Dana Point Part III: Specific Management and Surgical Aspects Erwin Oechslin, Siegrun Mebus, Ingram Schulze-Neick, Koichiro Niwa, Pedro T Trindade, Andreas Eicken, Alfred Hager, Irene Lang, John Hess, and Harald Kaemmerer ()〕 Pregnant women with Eisenmenger syndrome should be hospitalized after the 20th week of pregnancy - or earlier if clinical deterioration occurs. ==Etymology== Eisenmenger syndrome was so named by Dr. Paul Wood after Dr. Victor Eisenmenger, who first described〔Eisenmenger V.
