In adults, patent ductus arteriosus (PDA) closure is recommended if left atrial or left ventricular enlargement is attributable to the PDA with left-to-right shunt, pulmonary artery systolic pressure less than 50% systemic, and pulmonary vascular resistance less than one-third systemic.1
PDA closure in adults may be considered when there is evidence of left-to-right shunt if pulmonary artery systolic pressure is 50% or greater systemic, and/or pulmonary vascular resistance is greater than one-third systemic.1
Transcatheter PDA closure—e.g., with an Amplatzer™ Duct Occluder—is the standard of care in most cases.2
