Abbreviations
- Patent ductus arteriosus (PDA)
Synonyms
- Persistent arterial duct, patent ductus Botalli
Definitions
- Persistent postnatal patency of normal prenatal connection from pulmonary artery (PA) to proximal descending aorta
- Category: Acyanotic, ↑ pulmonary blood flow
- Hemodynamics: L → R shunt between aorta & PA
- PDA is frequently essential part of complex congenital heart disease
- Typical ductal-dependent lesions, including hypoplastic left heart syndrome, severe hypoplastic-type coarctation, & interruption of aortic arch: Conduit for systemic perfusion (R → L flow)
- D-transposition of great arteries: Necessary for admixture between systemic & pulmonary circuits (L → R flow)
- Pulmonary atresia & other severe cyanotic heart diseases with right-sided obstruction: Conduit for pulmonary perfusion (L → R flow)
- PDA is part of persistent fetal circulation syndrome: R → L flow
- Severe lung disease (meconium aspiration, surfactant deficiency disease, neonatal pneumonia)
- Primary pulmonary hypertension of neonate
