TYK192
The following are dependent upon an infusion of intravenous prostaglandin E- 1 to maintain a patent ductus arteriosus and provide systemic or pulmonary flow until surgical repair can be performed EXCEPT:
a) Triscuspid atresia.
b) Pulmonary atresia with intact interventricular septum
c) Hypoplastic left heart syndrome
d) Partial anomalous pulmonary venous drainage
e) Tetralogy of Fallot, with cyanosis
Answer
Answer d.
A patent ductus arteriosus, maintained by the infusion of prostaglandin E-1, will allow for left-to-right or right-to-left flow dependent on the lesion. This must continue until surgical repair can be undertaken. Lesions that are duct-dependent are tricuspid atresia, pulmonary atresia, HLHS, and Tetralogy of Fallot. PAPVD does not necessitate this arrangement.
