The senile valvular disease is mainly refers to the senile degenerative heart valve disease, or senile calcific heart valve disease. With the growth of age, the heart valve connective tissue degeneration, fibrosis, calcification, resulting in dysfunction of the valve or stent. It is one of the important causes of heart failure and sudden death in the elderly.
In recent years, with the continuous progress of cardiovascular disease detection methods, especially the advent of Doppler echocardiography for detecting, heart valve area, valvular regurgitation, valve, valve of pressure on both sides to provide a reliable basis of the diagnosis. On the other hand, due to the widespread use of antibiotics, rheumatic heart disease has been effectively controlled, coupled with the average life expectancy, the incidence of senile valvular disease increased year by year. Pomerance et al reported 162 patients with heart failure who died of heart failure in the autopsy, accounting for 45%, second only to coronary heart disease. Wong reported 78 cases of patients aged from 65 to 102 years, valvular degeneration accounted for more than 74%, who accounted for more than 90 years of age accounted for nearly 100%. The clinical data showed that the detection rate of calcific aortic stenosis was 29% in China, and the prevalence rate was about 19% in China. The incidence rate of calcific mitral valve disease was about 55%, and that of domestic was about 6%. The incidence rate was lower than that in foreign countries, which may be related to racial differences, living habits, diagnostic level and diagnostic criteria.
