As per available reports about 9 Conference Proceedings, 4 Conferences and 9 relevent journals are published by OMICS International relevant to Aortic stenosis.
Aortic stenosis, is a disease of the heart valves in which the opening of the aortic valve is narrowed. The aortic valve is the valve located between the left ventricle of the heart and the aorta, the largest artery in the body, which carries the entire output of to the systemic circulation. Aortic stenosis is now the most common valvular heart disease in the Western World. Symptoms related to aortic stenosis depend on the degree of valve stenosis. Most people with mild to moderate aortic stenosis are asymptomatic.
OMICS International organises 1000+ Global Events every year in Conference series, on Clinical, Medicine, Pharma and Science & Technology every year across USA, Europe, Asia, Middle East, Australia and UK with support from 1000 more scientific societies and Publishes 700+ open access journals which contains over 100000 eminent personalities, reputed scientists as editorial board and organizing committee members.
Scope and Importance
Aortic stenosis is now the most common valvular heart disease in the Western World. Symptoms related to aortic stenosis depend on the degree of valve stenosis. Most people with mild to moderate aortic stenosis are asymptomatic. Symptoms usually present in individuals with severe aortic stenosis, though they may occur in those with mild to moderate aortic stenosis as well. The three cardinal symptoms of aortic stenosis are loss of consciousness, anginal chest pain and shortness of breath with activity or other symptoms of heart failure such as shortness of breath while lying flat, paroxysmal nocturnal dyspnea, or pedal edema.
Angina in the setting of AS is secondary to the left ventricular hypertrophy (LVH) that is caused by the constant production of increased pressure required to overcome the pressure gradient caused by the AS. While the muscular layer of the left ventricle thickens, the arteries that supply the muscle do not get significantly longer or bigger, so the muscle may not receive enough blood supply to meet its requirement for oxygen. This ischemia may first be evident during exercise, when the heart muscle requires increased blood supply to compensate for the increased workload. The individual may complain of anginal chest pain with exertion. At this stage, a cardiac stress test with imaging may be suggestive of ischemia.
It is unclear why aortic stenosis causes syncope. One popular theory is that severe AS produces a nearly fixed cardiac output. When the patient exercises, their peripheral vascular resistance will decrease as the blood vessels of the skeletal muscles dilate to allow the muscles to receive more blood to allow them to do more work. This decrease in peripheral vascular resistance is normally compensated for by an increase in the cardio output. Since patients with severe AS cannot increase their cardiac output, the blood pressure falls and the patient will syncopize due to decreased blood perfusion to the brain. The effect of statins on the progression of AS is still unclear. The latest trials do not show any benefit in slowing AS progression, but did demonstrate a decrease in ischemic cardiovascular events. Angiotensin-converting enzyme (ACE) and angiotensin II receptors have been found in stenotic aortic valves. This leads to the hypothesis that the renin-angiotensin system may play a role in the progression of the disease. To date, there is no randomized trial examining the impact of ACE inhibitors in AS. Innasimuthu et al. showed that patients on bisphosphonates have less progression of aortic stenosis and some regressed. This finding led to multiple trials which is ongoing. Subsequent research has failed to confirm the initial positive result.
Market Analysis
Aortic stenosis is the most common cause of aortic stenosis (AS). While up to 1.5 million people in the U.S. suffer from AS, approximately 500,000 within this group of patients suffer from severe AS. An estimated 250,000 patients with severe AS are symptomatic. An estimated 80,000-85,000 AVR procedures are performed every year in the U.S.
