Question: where do you find semilunar valves and how do they differ from a/v valves

title: Heart valve
text: Disease of the heart valves can be congenital , such as aortic regurgitation or acquired , for example infective endocarditis . Different forms are associated with cardiovascular disease , connective tissue disorders and hypertension . The symptoms of the disease will depend on the affected valve , the type of disease , and the severity of the disease . For example , valvular disease of the aortic valve , such as aortic stenosis or aortic regurgitation , may cause breathlessness , whereas valvular diseaes of the tricuspid valve may lead to dysfunction of the liver and jaundice . When valvular heart disease results from infectious causes , such as infective endocarditis , an affected person may have a fever and unique signs such as splinter haemorrhages of the nails , Janeway lesions , Osler nodes and Roth spots . A particularly feared complication of valvular disease is the creation of emboli because of turbulent blood flow , and the development of heart failure .
