1 The addition of hemiarch replacement to aortic root surgery does not affect safety 
Sukit Christopher Malaisrie, MD, Brett F. Duncan, MD, Chris K. Mehta, MD, Mitesh V. Badiwala, MD, Dan Rinewalt, MD, Jane Kruse, RN, BSN, Zhi Li, MS, Adin-Christian Andrei, PhD, Patrick M.

2 Figure 1 Operative technique. The decision to perform a hemiarch, replacing the distal ascending aorta and proximal transverse arch, when the diameter of the proximal transverse arch is 4.0 cm or more. A, Aortic root and ascending aortic aneurysm, proximal arch less than 4.0 cm. B, ARR without hemiarch. C, Aortic root and ascending aortic aneurysm, proximal arch 4.0 cm or more. D, ARR with hemiarch. The Journal of Thoracic and Cardiovascular Surgery  , e2DOI: ( /j.jtcvs ) Copyright © 2015 The American Association for Thoracic Surgery Terms and Conditions

3 Figure 2 Standardized differences in the baseline covariates used in the construction of the PS model. Orange dots indicate the respective standardized difference in the original groups, and violet corresponds to the PS-matched groups. PS, Propensity score; CAD, coronary artery disease; MI, myocardial infarction; COPD, chronic obstructive pulmonary disease; CVD, cardiovascular disease; CVA, cerebrovascular accident; CABG, coronary artery bypass grafting; CV, cardiovascular; CHF, congestive heart failure; NYHA, New York Heart Association.

4 Figure 3 Kaplan–Meier estimates of medium-term overall survival in the original (A) and PS-matched (B) groups. Corresponding pointwise 95% CIs are depicted using dotted lines. MV, Mitral valve.

5 Kaplan–Meier estimates of medium-term overall survival in the original groups (A) and the PS-matched groups (B). Kaplan–Meier survival of original and matched groups for ARR alone versus ARR/hemiarch.
