📋Overview
Eisenmenger syndrome is a complex condition that develops as a long-term complication of certain congenital heart defects causing a left-to-right shunt. Over time, increased blood flow to the lungs leads to pulmonary hypertension, which eventually reverses the shunt direction to right-to-left, causing cyanosis and systemic hypoxemia. It is considered a severe form of pulmonary arterial hypertension associated with congenital heart disease.
