Insertion of the canula in the aorta (Ao) was problematicand suggested aortic dissection to the surgeon. A mobile linear shadow was seen in a long-axis mid-esophageal view of the ascending Ao(A, B) and the linear shadow was seen below the aortic wall on M-mode (arrow on C). A pulmonary artery (PA) catheter was presentin the right pulmonary artery (RPA) (D, E) and its excursion on M-mode was similar to the movement of the suspected aortic flap(arrow on F). An epiaortic examination of the ascending aortic root was performed which ruled out aortic dissection (G, H). The PAcatheter was also seen in the epiaortic view (G–J). The suspected flap was an artefact originating from the PA catheter in the RPA(LA, left atrium; LV, left ventricle; RV, right ventricle).(A)(B)AORTIC ARCHPEFigure 12.23 A 25-year-old woman was scheduled for aortic valve replacement. A pericardial effusion (PE) along the distal ascendingaorta was present and mimicked an aortic dissection.
