[[File:7. PDA.png|thumb|right|Figure 7. Echocardiographic image showing a coil in the ductus arteriosus. P=pulmonary artery, A= aorta.]] | |||
Patients with an open PDA have an increased risk of infectious endarteritis, heart failure, pulmonary hypertension and most of these patients become symptomatic in adulthood. Patients with a non-restrictive PDA rarely reach adulthood, unless the pulmonary vascular resistance increases leading to a decrease in left ventricular overload. This hemodynamic state is known as Eisenmenger syndrome in which the shunt is reversed and there is cyanosis present. Patients in who the ductus is closed in childhood have a normal life expectancy. | Patients with an open PDA have an increased risk of infectious endarteritis, heart failure, pulmonary hypertension and most of these patients become symptomatic in adulthood.
