Type A aortic dissection in patients with bicuspid aortic valves: clinical and pathological comparison with tricuspid aortic valves

Abstract

Compared with patients with TAV, patients with BAV with type A AD are younger, have less hypertension, more valve stenosis and previous AVR, higher maximal aortic dimension, worse aortic medial degeneration, high prevalence of aortic coarctation, and 1 out of 2 have known aortic dilatation prior to AD. Implementation of current guidelines could have theoretically prevented AD in several patients with BAV.
