What is the most feared complication of infective endocarditis?

• A. Myocardial infarction
• B. Pulmonary embolism
• C. Aortic dissection
• D. Congestive heart failure (CHF)

Answer: (D)

Valvular destruction from infective endocarditis can lead to acute, severe valvular regurgitation, especially of the mitral or aortic valves. This suddenly overwhelms the heart with volume and pressure, causing rapid pulmonary congestion and congestive heart failure. The rapid progression and high risk of death with abrupt decompensation make congestive heart failure the most feared complication. Other problems, like embolic events or abscess formation, can occur, but they do not typically provoke such immediate, life-threatening decompensation as acute heart failure from valve destruction.
