2 Fig 1 Kaplan-Meier midterm survival curve. Number of subjects at risk is shown below the chart. (OPEN = open aortic repair; TEVAR = thoracic endovascular aortic repair.)

3 Fig 2 Mean difference in total (solid bar) and direct hospital costs (hollow bar; difference is thoracic endovascular aortic repair minus open aortic repair) for surveillance imaging among survivors at each follow-up interval. Percentages below show the compliance rate of patients undergoing thoracic endovascular aortic repair with follow-up imaging at each interval.

4 Fig 3 Mean difference in physician relative value units (RVUs; difference is thoracic endovascular aortic repair minus open aortic repair) for surveillance among survivors at each follow-up interval. Combined RVUs = Radiologist RVUs + Surgeon RVUs. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions
