Which of the following is not a complication of infective endocarditis -
Ans. is none or 'b' i.e., Suppurative Pericarditis Complications of Endocarditis o Valvular insufficiency or stenosis with cardiac failure Myocardial ring abscess with possible perforation of aoa, interventricular septum or free wall. Suppurative pericarditis with endocarditis on aificial valves, paial dehiscense with paravalvular leak. o Embolic complications With left sided lesions (a) Brain (cerebral infarct or abscess, meningitis) (b) Hea (Myocardial infarction) (c) Spleen (abscesses) (d) Kidney (abscesses), other sites. o With Right sided lesions (a) Lung (infarcts, abscess, pneumonia) o Renal complications Embolic phenomenon Focal and diffuse glomerulonephritis due to trapping of antigen - antibody complexes which may lead to hematuria, albuminuria or renal failure. Multiple abscesses : especially with acute staphylococcal endocarditis. So according to Robbins all of the given options can be seen. Even Braunwald's Hea disease mentions all the four options as complications of infective endocarditis. o If we have to go for one we will prefer suppurative pericarditis as the answer because in infective endocarditis mostly autouimmune pericarditis occurs.
Myocardial ring abscess
Suppurative pericarditis
Myocardial infarction
