Answer

In acute IE, the frequency of aneurysms and other suppurative intracardiac complications is high. In addition to valvular insufficiency, other intracardiac complications of acute IE include (1) aortocardiac and other fistulas, (2) aneurysms of the sinus of Valsalva, (3) intraventricular abscesses, (4) ring abscesses, (5) myocardial abscesses, (6) mycotic aneurysms, (7) septic coronary arterial emboli, and (8) pericarditis.

In patients with acute disease, especially disease caused by S aureus infection, emboli almost inevitably lead to abscesses in the areas where they are deposited. Multiple abscesses can occur in almost every organ, including the kidneys, heart, and brain. Mycotic aneurysms may occur in almost any artery. Paradoxically, they are less common in patients with acute IE. [61, 62]
