Eisenmenger syndrome is an advanced form of pulmonary artery hypertension . In this condition, the arteries that carry blood from the heart to the lungs narrow. This makes the pressure of blood flow against the walls of the arteries (blood pressure) too high. The heart must work harder to pump blood into the lungs. This causes lung damage.
