The presence of abnormal circulatory shunting was determined by transesophageal bubble-contrast echocardiography. The timing of image acquisition is indicated by the white arrowheads on the ECG strip and explained by the text below the images. (A) Posterior transverse view before agitated saline-air mixture injection (RA = right atrium; LA = left atrium; AV = aortic valve). (B) During agitated saline-air mixture injection bubbles are visible only in the right atrium (white arrow). (C) One and a half heart-beat after agitated saline-air mixture injection air bubbles are detected both in the right and left atria (white arrows).
