Echocardiographic findings. a Simultaneous transthoracic echocardiography and colour-flow Doppler imaging of the left atrium. The colour-flow Doppler imaging reveals turbulent flow from the dilated pulmonary vein (*) into the left atrium, which is also continuous. b Continuous Doppler echocardiography shows continuous blood flow from the pulmonary vein, with a peak velocity of 3.14Â m/s through the pulmonary vein stenosis, indicating severe pathology. LA: left atrium, RA: right ventricle
