Color-Doppler evaluation revealed left to right shunt in the basal portion of the interatrial septum without the involvement of the interventricular septum [Figure 1] and moderate mitral valve regurgitation.
Preoperative transesophageal echocardiography: On the left, mid-esophageal short axis view focused on interatrial septum showing morphological evaluation of the interatrial communication. On the right, mid-esophageal four chamber view: Color-Doppler evaluation showing left to right shunt. RA = Right atrium, LA = Left atrium, LAA = Left atrium appendage

For further evaluation, a transesophageal echocardiography was performed, confirming an atrial septal defect, ostium primum type, with left-to-right shunt [Figure 2].
