A medical condition involving inflammation of tissue within or around the heart, related to carditis.
From Greek en- (in) + kardia (heart) + -itis (inflammation suffix used in medical terminology). This appears to be an archaic or alternative form of endocarditis or myocarditis.
Endocarditis (the modern medical term) can be caused by bacteria from infected teeth entering the bloodstream—which is why dentists take heart conditions so seriously and sometimes prescribe antibiotics before dental work.
