Patent ductus arteriosus.

Patent ductus arteriosus (PDA) is a congenital disorder in heart, wherein the ductus arteriosus fails to close after birth. This leads to the generation of a left-to-right shunt, leading to pulmonary hypertension. Color Doppler echocardiography is essential for the diagnosis. The identification of a diastolic flow oriented in the opposite direction in the pulmonary artery finalizes the diagnosis. We present the case of a 4 year old patient with systolic and diastolic left parasternal lift, echographically diagnosed with patent ductus arteriosus. The typical echographic aspects for this cardiac malformation are thoroughly detailed.
