Infected coronary artery aneurysm (ICAA) is rare complication of pre-existing coronary artery disease of atherosclerotic or other genesis, percutaneous coronary intervention (PCI), infective endocarditis or extracardiac infection, accompanied by high mortality. 83–86% of infected patients are males, with average age of 55.44 years. The most frequently affected vessel is right coronary artery (40–45%). In 53.3–55% of cases, the etiological pathogen is Staphylococcus aureus, in 20–21% – Streptococcus. Usually, IACA have a large size, reaching an average of 3.4 cm, however, an increase of up to 9 cm is possible. According to computed tomography (CT) angiography, in 54.2% of cases, a lobular contour or saccular shape of the coronary artery are visualized, in 87.5–89% of cases, a thickening of the wall or parietal thrombi are detected, in 79.2–81% – pericardial thickening or pericardial effusion. IACA usually has a lobular or saccular shape, reach significant sizes and are characterized by a thickening of the coronary artery wall. This complication is often accompanied by hydropericardium. The identification of these changes in the patient, along with fever, an already existing infectious process, or a recent history of PCI allow to suspect IACA.
