Cardiac echinococcosis is a rare condition, and its manifestations are protean depending upon its site of infestation. We report a case of hydatid heart disease presenting like an acute cardiac ischemic episode associated with a rise in serum cardiac enzymes secondary to left ventricular free wall dissection caused by ruptured intramyocardial echinococcal cyst. The resultant complex cardiac anatomy was characterized fully by echocardiographic examination.

BackgroundInfection of cardiac implantable electronic devices is a serious cardiovascular disease and it is associated with a high mortality. Mycobacterium species may rarely cause cardiac implantable electronic devices infection.Case presentationWe are reporting a case of miliary tuberculosis in an Arab patient with dilated cardiomyopathy and a cardiac resynchronization therapy-defibrillator device that was complicated with infection of his cardiac resynchronization therapy-defibrillator device. To our knowledge, this is the third case in the literature with such a presentation and all patients died during the course of treatment. This underscores the importance of early diagnosis and management. We also performed a literature review of reported cases of cardiac implantable electronic devices infection related to Mycobacterium species.ConclusionsCardiac implantable electronic devices infection due to Mycobacterium species is an uncommon but a well-known entity. Early diagnosis and prompt management may result in a better outcome.
