this is another stupid question. ok, as it is asked I agree with you guys on G+ bacteria and ACUTE endocarditis, but:
extracting fluid from the pericardial cavity is done in PERIcarditis, in endo usualy you don't have an exudate, posibly an transudate from right heard failure and gingivitis, from my knowledge is is treated with drugs, antibiotics. if you have an abscess then you incise it and that's not a gingivitis anymore, that's a apical abscess
do correct my intervention
