Echocardiographic images of valvular pulmonary stenosis and patent ductus arteriosus. a Right parasternal short-axis (RPSA) image acquired at the heart base level showing right ventricular concentric hypertrophy with dysplastic and a fused pulmonary valve during systole. b Continuous-wave Doppler image showing pulmonary stenosis (PS) with a peak transpulmonary velocity of 7.3 m/s and a pressure gradient (PG) of 213 mmHg. c RPSA image showing prolapse towards the right ventricle during diastole. d CWD image showing a peak diastolic pulmonary regurgitation (PR) velocity of 3.3 m/s and a PG of 44 mmHg. e Left parasternal long-axis image showing a patent ductus arteriosus (PDA). f At the same view, a CWD image showing left-to-right shunt flow with a peak systolic PG of 144 mmHg and an end-diastolic PG of 59 mmHg. A ampulla of patent ductus arteriosus, AO aorta, DA descending aorta, LMPA left main pulmonary artery, MPA main pulmonary artery, O orifice of patent ductus arteriosus facing main pulmonary artery, RV right ventricle
