In 3 cases of T.A.P.V.C. below the diaphragm, the common pulmonary vein produced an anterior indentation in the lower portion of the barium filled esophagus. This occurred a short distance above the diaphragm, yet slightly below the expected site of left atrial indentation. With further experience, this may prove to be a uniformally diagnostic sign, especially if carefully controlled barium swallow study is performed in all infants with respiratory distress.
A rare type of T.A.P.V.C. above the diaphragm is reported to show that similar esophageal indentations are not specific for T.A.P.V.C. below the diaphragm.
