1 Acute aortic dissection with coronary ostium involvement and aortic valve regurgitation: Three-dimensional visualization with multislice computed tomography  Gudrun Maria Feuchtner, MD, Thomas Schachner, MD, Guy Friedrich, MD, Herwig Antretter, MD, Johannes Bonatti, MD, Dieter zur Nedden, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 130, Issue 2, Pages 587.e1-587.e3 (August 2005) DOI: /j.jtcvs Copyright © 2005 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 Acute ascending aortic dissection. The site of the intimal tear was the stent graft anastomosis (white arrow). The intimal flap forms a true (T) and false (F) lumen. Note the partially thrombosed stent graft, which is placed in the descending aorta (DA). Images are displayed with multiplanar reformation. PA, Pulmonary artery.

3 Figure 2 The dissection involved the left and right coronary ostium, which caused acute myocardial ischemia. LA, Left atrium; CX, circumflex artery; RC, right coronary artery; LM, left main coronary artery; AA, ascending aorta; LV, left ventricle.

4 Figure E1 Left, The aortic valve is displayed closed without aortic regurgitation (normal finding). RCC, Right coronary cusp; LCC, left coronary cusp; NCC, noncoronary cusp. Right, Three-dimensional MSCT image of the aortic valve before surgical intervention is displayed. Aortic valve leaflets did not close up during diastole, and a central triangular leakage could be displayed suggesting aortic valve regurgitation (AR). Black arrows denote the regurgitation jet, which is displayed 3-D by applying volume-rendering technique. CA, Aortic valve calcification.
