Pulsed wave Doppler interrogation in a patient with a patent ductus arteriosus and significant left-to-right shunting with retrograde diastolic flow
Pulsed wave Doppler interrogation in a patient with a patent ductus arteriosus and significant left-to-right shunting with retrograde diastolic flow
In a patient with a patent ductus arteriosus (PDA) and significant left-to-right shunting, pulsed Doppler echocardiography shows retrograde diastolic flow in the descending aorta (arrows) towards the PDA.
