RESULTS: for the total of 105 patients, 2.9% presented G0; 8.6% G1; 31.4% G2; 33.3% G3 and 23.8% G4. A statistically significant difference (p = 0.017) was found in the average aortic parietal thickness between the different degrees of pathological lesion. 88% of patients had aortic stenosis, within this group prevailed G2 (mild-moderate) and G3 (moderate). In contrast, in patients with aortic insufficiency, 82% had G3 (moderate) and G4 (severe). CONCLUSION: we could conclude the walls of the AAs of patients with bicuspid valves replacement without aortic dilation at the time of surgery showed a direct relationship between greater histological damage and greater parietal thickness (except in group 0), relevant findings that may have implications in the surgical treatment and the long term follow-up of patients.
