Pregunta 2
Pregunta
The infective endocarditis is characterized by:
Respuesta
-
vegetation often occurs at the point where the pressure is higher (at the chamber side of the mitral valve, the aortic side of the aortic valve)
-
mature vegetation consisting of cardiomyocytes, fibroblasts, and inflammatory cells of the bacterium

cerebral embolism may occur in more than 2/3 of patients
-
the native Valve is a frequent obstruction due to vegetation
-
Endocarditis is reflected by vegetation on the valves, abscesses in the field of valves and valve perforation

-
rheumatoid carditis treated with steroids
-
the acute phase is characterized by a migratory polyarthritis
-
only affects endocardial
