Epicardial cysts: report of two rare cases.

Epicardial cysts originating directly from the epicardium are seen very rarely. Complete surgical excision is recommended when these cysts are detected. If cysts compress surrounding vital structures, cardiopulmonary bypass (CPB) should also be considered. We report herein 2 cases of multiloculated epicardial cysts, both of which were successfully excised, 1 with CPB.
