Based on the transesophageal echocardiography what is the diagnosis?

Answer: Transesophageal echocardiography (TEE) in 4 chamber view showing cross section of Fontan conduit.

Editorial comment: The Fontan pathway in echocardiography is seen along the right level border of the native atria and bypass the entire heart to create a diversion of superior and inferior vena caval (IVC) flow to the pulmonary artery. Progressive IVC enlargement, spontaneous echo contrast and progressive atrial enlargement are some clues to dysfunction of Fontan circulation.
