Domestic valve simple mitral / aortic valve replacement

Cardiac valvular disease refers to a disease involving two or more heart valves at the same time. According to a large group of autopsy reports from abroad, combined valve disease accounts for about 27% to 41.5% of heart valve disease. However, according to statistical analysis of clinical data of large groups of surgical operations at home and abroad, combined valve disease accounts for about 11.5% to 28% of heart valve disease surgery, with an average of about 15%. In combined valvular disease, mitral valve with aortic valve double lesions is the most common, accounting for 48% to 87%; followed by mitral valve with aortic and tricuspid valve trivalvular diseases, accounting for 7% to 24.5%; Mitral valve and tricuspid valve disease are also common, but most of them are organic mitral valve disease combined with functional tricuspid valve disease, and organic mitral and tricuspid valve disease account for only about 2% to 4%; Aortic valve disease with tricuspid valve disease is rare, accounting for <5%; while tricuspid and pulmonary valve bivalvular disease, mitral, tricuspid, aortic, and pulmonary valve 4-valve disease are very rare .
