What are the predictors of late proximal aortic dissection or aneurysm formation at the time of aortic valve replacement?
Aortic regurgitation combined with fragile and thinned aortic walls at the time of aortic valve replacement predicts a high risk for late postsurgical aortic dissection.
Kodolitsch et al. (1999) studied this question.
