Linear growth pattern can be used to predict ascending aortic aneurysm growth.

Current guidelines recommend that surveillance imaging should be performed at least every third year for patients with ascending thoracic aortic aneurysm (ATAA) even though such aneurysms' growth rate is mostly minimal. The purpose of this study was to clarify the pattern of the growth of ATAAs in a real-life patient population to adjust the optimal timing of aortic surveillance for each patient. This study includes patients ( = 209) who had been followed due to ATAA in the central hospital of North Karelia in Eastern Finland between years 2007 and 2023.
