Abstract: Calcific aortic stenosis is the most common cardiovascular disease in Western countries after coronary artery disease and hypertension. So far, there is no effective medical therapy able to stop or slow the progression of aortic stenosis. The only available treatments are surgical or transcatheter aortic valve replacement for patients with severe symptomatic aortic stenosis. In this context, it is crucial to develop efficient pharmaceutical therapy able to slow the stenosis progression and thus prevent such invasive intervention. In the past, aortic stenosis was thought to be a simple degenerative process of the aortic valve linked to aging. However, the advances performed during the last two decades showed that aortic stenosis is a highly complex and actively regulated disease, especially involving pathological processes close to atherosclerosis or arteriosclerosis. Furthermore, identified the key factors involved in the disease progression is essential to understand the pathogenesis of aortic stenosis. In this regard, hypertension is a common comorbidity of aortic stenosis and previous findings suggest that it may have an impact both on the development and progression of aortic stenosis. The primary hypothesis of this MSc project was that systolic hypertension, the most prevalent form of hypertension in patients with aortic stenosis, leads to faster progression of aortic valve calcification. Thus the main objective of this study was to assess the impact of systolic hypertension on the progression of aortic valve calcification assessed by multidetector computed tomography in patients with aortic stenosis.
