Aortic stenosis is the most common valvular heart disease among adult subjects in western countries The current treatment for aortic stenosis is aortic valve replacement. The possibility of a medical treatment that can slow the progression of aortic stenosis is very fascinating and statins have been tested to reduce the progression of degenerative aortic stenosis (DAS). The rationale for statin treatment in DAS has a deep pathophysiological substrate, in fact inflammation and lipid infiltration constitute the same histopathological pattern of both aortic stenosis and atherosclerosis and these two conditions have the same risk factors. Whether retrospective studies have shown some efficacy of statins in halting the progression of DAS, prospective trials have shown controversial results. A recently published large and randomized controlled trial SEAS found that statins have no significant effect on the progression of aortic stenosis, the ASTRONOMER, recently confirmed this data. The most plausible hypothesis is that coronary artery disease and DAS, have a common pathogenetic background and a distinct evolution due to different factors (mechanical stress, genetic factors, interaction between inflammatory cells and calcification mediators). Thus, treatment with statins is not recommended in patients with valvular aortic stenosis and without conventional indications to lipid-lowering treatment.

The underlying pathology in aortic stenosis (AS) and coronary artery stenosis (CAS) is similar including atherosclerosis and calcification. We hypothesize that coronary artery calcification (CAC) is l...
Aortic valve replacement for calcific aortic valve stenosis is one of the more common cardiac surgical procedures. However, the underlying pathophysiology of calcific aortic valve stenosis is poorly u...
Calcific aortic valve stenosis (CAVS) is a serious clinical problem. The strongest predictor of CAVS progression is the amount of calcium in the aortic valve. The pathogenesis of CAVS is largely consi...
In approximately one third of patients presenting with suspected severe aortic stenosis, there is a discrepancy between a severely reduced aortic valve opening area (
An important proportion of patients with aortic stenosis (AS) have a 'low-gradient' AS, i.e. a small aortic valve area (AVA
There is evidence that the degenerative changes leading to aortic stenosis are caused by a chronic inflammatory process. Furthermore the development of aortic stenosis is partially depende...
Bicuspid Aortic Valve (BAV) is the most common congenital heart disease affecting 1-2% of the population. The aortic dilation and aortic valve degeneration are common complications in pati...

Aortic stenosis is a major cause of morbidity around the world. Progressive aortic stenosis leads to cardiac hypertrophy as a compensatory response. A maladaptive response may lead to hear...
This study aims to evaluate whether baseline 18F-sodium fluoride uptake activity at aortic valve could predict aortic stenosis progression in moderate aortic stenosis. Patients with moder...
A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
A pathological constriction occurring in the region above the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
A pathological constriction occurring in the region below the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
