1 Simultaneous sizing and preoperative risk stratification for thoracic endovascular aneurysm repair: Role of gated computed tomography  Felix J.V. Schlösser, MD, Hamid R. Mojibian, MD, Alan Dardik, MD, PhD, Hence J.M. Verhagen, MD, PhD, Frans L. Moll, MD, PhD, Bart E. Muhs, MD, PhD  Journal of Vascular Surgery  Volume 48, Issue 3, Pages (September 2008) DOI: /j.jvs Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Graph shows coronary calcium scores in asymptomatic men. The small red block represents the percentage of people with the same age and sex of the presented patient who have less calcium in the coronary arteries. The relatively high calcium score in combination with other cardiac findings in this patient would be a good indication for referral of the patient to a cardiologist before surgery.

3 Fig 2 A, Cross-sectional views of the left anterior descending coronary artery are shown. B, This curved planar reformatted image of the left anterior descending coronary artery shows a heavily calcified and diffusely diseased artery.

4 Fig 3 In a semi-automated fashion, the dynamic images from 0% to 90% of the cardiac cycle were used to calculate ejection fraction (end-diastolic volume minus end-systolic volume) and the end-diastolic myocardial mass of the left ventricle.

5 Fig 4 The three leaflets of the aortic valve are excellently visible in this electrocardiogram-gated computed tomography image. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

6 Fig 5 A prosthetic valve was found in one patient. The electrocardiogram-gated computed tomography images show the prosthetic valve in two different phases: (A) open during the systolic phase and (B) closed during the diastolic phase of the cardiac cycle.
