[Epidemiology and etiology of acquired heart valve diseases in adults].

Acquired valvular heart disease remains common. Their causes have changed during the past 30 years with the increase in life expectancy and with the decrease in the incidence of rheumatic fever. Calcific aortic stenosis is currently the predominant cause, followed by left heart valvular regurgitations due to degenerative disease and infective endocarditis. Post-radiation valvular disease might become more frequent in the future. More recently, left heart valvular diseases were observed in the United States in patients treated by anorexigen treatment.
