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.
动脉导管未闭（PDA）是一种先天性心脏疾病，即动脉导管在出生后未能闭合。这会导致左向右分流的产生，进而引发肺动脉高压。彩色多普勒超声心动图对诊断至关重要。在肺动脉中发现舒张期血流方向相反即可确诊。我们报告一例4岁患者，其胸骨左缘有收缩期和舒张期抬举，经超声心动图诊断为动脉导管未闭。本文详细阐述了这种心脏畸形典型的超声心动图表现。
