A 30-year-old male was referred to our Department due to ventricular tachycardia. Based on symptoms, echocardiography and laboratory examinations acute myocarditis was diagnosed which was confirmed by cardiac MRI. Besides myocarditis, MRI also indicated the presence of an underlying myocardial disease which was also verified by a control examination performed 2 months later, following the resolution of myocardial edema. Results of the MRI, resting 12-lead ECG and ECG characteristics of ventricular tachycardia fulfilled the diagnostic criteria of arrhyhtmogenic right ventricular cardiomyopathy (ARVC).
ARVC predisposes to episodes of acute myocarditis resulting in deterioration of the underlying cardiomyopathy. Based on case reports, it is not uncommon that ARVC is first diagnosed during an episode of acute inflammation. Certain gene mutations (most commonly DSP) carry an increased risk for myocarditis in ARVC.
