Answer

Acute NVE frequently involves normal valves and usually has an aggressive course. It is a rapidly progressive illness in persons who are healthy or debilitated. Virulent organisms, such as S aureus and group B streptococci, are typically the causative agents of this type of endocarditis. Underlying structural valve disease may not be present.

Subacute NVE typically affects only abnormal valves. Its course, even in untreated patients, is usually more indolent than that of the acute form and may extend over many months. Alpha-hemolytic streptococci or enterococci, usually in the setting of underlying structural valve disease, typically are the causative agents of this type of endocarditis.
