Non-rheumatic Degenerative Mitral Valve Disease

Data on prevalence and related metrics, as YLD and DALY, obtained from the current version of the GBD Study should be viewed with caution. In GBD study, prevalence estimations are based in modeling that includes several factors, as socioeconomic indices, and this Is not necessarily the ideal method for diseases in which the presence of disease is related to the presence of a vector in a specific subregion of the country, as is the case for Chagas disease. Although national estimates of prevalence and burden of disease metrics seems adequate, the metrics for the individual federative units sometimes are not completely congruent with the epidemiological situation of the disease in Brazil. The 2020 version of the GBD study are being corrected for this discordance.
