The specific aims of this study are to:
- Establish baseline levels of circulating MMP-2 and -9 , TIMP-1and- 2 and TGFB levels in individuals with bicuspid aortic valve and ascending aortic or aortic sinus measurements >40mm.
- Assess the effect on MMP levels during treatment with losartan, an angiotensin II receptor blocking agent.
- In the setting of losartan therapy for one year, evaluate the response of MMP levels in these patients, and clinical outcomes including effects on aortic growth rate

- Inflammatory Markers Levels [ Time Frame: Baseline and 12 months ]Changes in levels of Matrix Metalloproteinase (MMP-2, MMP-9), Tissue Inhibitor of Metalloproteinases (TIMP 1, TIMP 2), & Transforming Growth Factor-Beta (TGFB) in circulation while taking medication from baseline at 3 months, 6 months and 12 months. The 12 month levels were the primary outcome.
