Eisenmenger's syndrome

Quick Reference

An anatomical defect of the heart in which a left-to-right shunt causes increased flow through the pulmonary vasculature, causing pulmonary hypertension. This in turn can cause an increase in pressure in the right side of the heart so that deoxygenated blood is forced to the left and into the peripheral circulation where it causes cyanosis. See atrioventricular septal defect.
