A review of postmortem materials from two teaching hospitals, accumulated in a 14-year period (1962--1975), disclosed 63 patients with myocardial abscesses among 12,359 autopsies, an incidence of 0.5%. All 63 patients had multi-focal myocardial abscesses; the lesions were grossly discernible in six patients. Coexisting infective endocarditis was present in approximately 20% (12) of the 63 patients with myocardial abscesses. ⋯ Eighty-one per cent (51) of 63 patients had abscesses in one or more extracardiac organs. It appeared that most of the myocardial abscesses had resulted from disseminated sepsis. Surgical conditions, malignancy and alcoholic hepatic disease were the most frequent primary conditions in patients with myocardial abscesses.
