Answer

Definitive pathological diagnosis is established by demonstrating microorganisms, by culture or histology, in vegetations removed by surgery, embolectomy, or drainage of an intracardiac abscess. Alternatively, a definitive clinical diagnosis is made based on the presence of 2 major criteria, 1 major criterion and 3 minor criteria, or by 5 minor criteria.
