Antecedentes: la reparación de la insuficiencia tricuspídea funcional está indicada en casos de insuficiencia cardíaca, generalmente, asociada a enfermedades de las válvulas cardíacas izquierdas y en algunos casos de enfermedad coronaria o cardiopatías congénitas. Objetivo: evaluar los resultados a largo plazo de la reparación tricuspídea en pacientes operados en la región centro sur de Chile.

Several studies indicate that negative impacts on water quality are minimally related to silviculture. We analyzed the water quality of a stream in a silvicultural region in southern Brazil, considering the relationship between the components of the landscape and biotic quality indexes, merging physical and biological descriptions of the macroinvertebrate community and environment. We selected three points in the Faxinalzinho stream to collect macroinvertebrate samples and to perform perceptual analysis from September to December/2014, applying the Biological Monitoring Working Party (BMWP') and the Rapid Assessment Protocol for Habitat Diversity (RAPHD). Diversity metrics and a Non-metric Multidimensional Scaling (NMDS) were also applied to explore variations in the aquatic community abundance matrix, associating the data to Land Use/Land Cover. A total of 569 individuals was recorded, distributed in 27 taxa. The results showed good water quality in the studied points, mainly when compared to other studies regarding urban rivers. However, we found negative effects in the site with higher silviculture land cover, presenting acceptable water quality (BMWP'= 66) and altered environmental conditions (RAPHD= 51), while the other sites presented excellent water quality (BMWP'= 127-131) and natural environment (RAPHD= 85-91).
