endocarditis
Infection of the inner lining of the heart chambers and valves, typically caused by bacteria.
Full Definition
Endocarditis is a serious infection involving the endocardium, most commonly affecting heart valves. It can be acute (rapidly progressive) or subacute (slowly developing), with Staphylococcus aureus and Streptococcus viridans being common causative organisms. The condition may lead to valve destruction, heart failure, systemic embolization, and death if untreated. Surgical intervention may be required for valve replacement, debridement of infected tissue, or drainage of abscesses. Predisposing factors include prosthetic valves, congenital heart disease, and intravenous drug use.
Usage
Usage note: Specify acute vs. subacute and causative organism when known.
