Abstract

Myocardial abscess is a suppurative infection of the myocardium, endocardium, native or prosthetic valves, perivalvular structures, and cardiac conduction system. It develops in about 20% of patients with infective endocarditis. Due to avascular and fibrous structures, valvular regions are commonly involved. More precisely, the aortic valve (AV) rings area of the native or prosthetic valve is usually affected. The occurrence of myocardial abscess within the free wall of the left ventricle (LV) without any evidence of infective endocarditis is a rare phenomenon and is infrequently reported in medical literature. We report a case of myocardial abscess cavity within the inferior wall of the LV in a patient who was on prolonged intake of antidepressants. This was an incidental postmortem finding without any other evidence of infective endocarditis. There was also >70% stenosis of the coronary arteries.
