A condition associated with VENTRICULAR SEPTAL DEFECT and other congenital heart defects that allow the mixing of pulmonary and systemic circulation, increase blood flow into the lung, and subsequent responses to low oxygen in blood. This complex is characterized by progressive PULMONARY HYPERTENSION; HYPERTROPHY of the RIGHT VENTRICLE; CYANOSIS; and ERYTHROCYTOSIS.

(eisenmenger syndrome) A rare respiratory disease associated with unoperated congenital heart disease and characterized by congenital heart malformations with reversed or bi-directional shunting through an intra-cardiac or intervascular (usually aorto-pulmonary) communication with the development of PAH.

(eisenmenger syndrome) A syndrome characterized by the reversal of a septal defect-associated left-to-right shunt due to the resulting secondary pulmonary hypertension. The presence of the pulmonary hypertension causes increased pressure in the right heart chambers resulting in the reversal of the shunt into a right-to-left shunt. Signs and symptoms include cyanosis, pulmonary hypertension, heart failure, and high red blood cell count.

Eisenmenger syndrome is a complication of uncorrected large intracardiac or aortic to pulmonary artery left-to-right shunts. Increased pulmonary resistance may develop over time, eventually leading to severe pulmonary hypertension, bidirectional shunting with progressively increasing right-to-left shunting. Cyanosis and hypoxia...

Eisenmenger syndrome refers to any untreated congenital cardiac defect with intracardiac communication that leads to pulmonary hypertension, reversal of flow, and cyanosis. The previous left-to-right shunt is converted into a right-to-left shunt secondary to elevated pulmonary artery pressures and associated pulmonary vascular disease.

Eisenmenger (I-sun-meng-uhr) syndrome is a complication of a heart defect that you're born with (congenital).

Eisenmenger syndrome (ES) refers to the combination of a type of high blood pressure that affects the blood vessels of the lungs and heart (pulmonary hypertension), and abnormal blood flow through the heart. ES most often occurs in people who are born with a heart defect (congenital heart defect) that does not get repaired in childhood....
