Diagnosis of an uncommon case of myocarditis by cardiac magnetic resonance imaging: ventricular tachycardia caused by inflammatory left ventricular microaneurysms.
Cardiac magnetic resonance imaging (CMRI) has recently proved to be a powerful tool in the diagnosis of myocarditis. We report a case of myocarditis diagnosed with CMRI in a rare setting: An episode of ventricular tachycardia (VT) arising from the left ventricle associated with a unique ventricular microaneurysm in a patient free of coronary disease. Because of this benign feature, the patient was discharged with antiarrhythmics with no further investigation. A 9-month follow-up revealed no VT recurrence. This case demonstrates the importance of CMRI in patients suffering from apparently idiopathic VT originating in the left ventricle.
