Diagnostics

Endomyocardial biopsy

• Myocyte necrosis (may be focal)
• Inflammatory cell infiltrate (e.g., lymphocytic)

Treatment

Complications

• Progression to dilated cardiomyopathy (∼ 15% of cases)
• Heart failure or sudden cardiac death: probably due to ventricular tachycardia or fibrillation (common in adults < 40 years old)
• Acute and/or persistent arrhythmias
• Atrioventricular block
• Intracardiac thrombi formation, which can result in systemic embolization
