ASD flow: Left to right shunt from left atrium to right atrium. Red colour of the flow is because flow is towards the transducer; right to left shunt will be blue in colour in the subcostal view as the flow would be away from the transducer. Slight mosaic colour of the ASD flow jet is seen, indicating mild turbulence of the stream. Colour jet from the superior vena cava is joining the ASD flow in the right atrium. Care should be taken to avoid mistaking SVC flow for an ASD flow with an echo drop out. Here the ASD left to right flow can be clearly seen traversing the defect in the interatrial septum from left atrium to right atrium.<\/p>\n<p>In this view the ASD is seen to have good rims on either side, suggesting that it may be an ideal case for <a href=\"https:\/\/johnsonfrancis.org\/professional\/device-closure-of-atrial-septal-defect-asd\/\">device closure<\/a>. Good rims all around the ASD is considered as a favourable sign when device closure is being considered as the device is likely to be well seated and held in place during movements of the heart. This minimizes the chance of device migration, as may occur in cases where one or more rims are defective.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ASD on colour Doppler echocardiogram Subcostal view showing a 15 mm ASD on colour Doppler echocardiogram SVC flow: Flow from superior vena cava into the right atrium.
