In this episode, we review the physiology, imaging, and management of patent ductus arteriosus (PDA). What is the classic murmur of PDA, and how does it change with shunt reversal? Why do patients with PDA get left heart enlargement instead of right heart enlargement? How does the differential cyanosis seen in PDA with Eisenmenger syndrome present? How do you calculate pulmonary artery systolic pressure using PDA velocity? How do you distinguish the Doppler CW profile of PDA from pulmonary valve regurgitation? What are the indications for PDA closure, and why are Qp ratios not used as they are for ASD and VSD? Tune in for answers to these questions.
