What is the typical growth rate of ascending thoracic aortic aneurysms and what factors predict it?
Ascending thoracic aortic aneurysms grow slowly at 0.25 to 1 mm/year, suggesting that annual imaging surveillance may be unnecessarily frequent for most patients.
Considering all pathogeneses, ascending TAAs typically grow at 0.25 to 1 mm/y, and thus annual surveillance is likely too frequent to detect growth in most patients. Studies vary widely in populations, methodology, and outcomes, with few high-quality longitudinal studies and no predictors of aortic GR.
Henry et al. (Thu,) studied this question.
