Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited disease affecting of ARVC with left ventricle (LV) involvement, with no typical symptoms and no relevant Family history was unremarkable, and physical examination results were normal... Monitoring using a 24-h Holter electrocardiogram documented only occasional ventricular extrasystoles with left bundle branch block morphology and no significant cardiac arrhythmia... These findings suggested a diagnosis of ARVC with LV involvement... negative family history, three major criteria led to the definite diagnosis of ARVC: Future investigations should clarify the clinical relevance of these findings and the prognosis of patients with biventricular arrhythmogenic cardiomyopathy.

f01: Resting 12-lead ECG showing T-wave inversion from V2 to V6 (major diagnosticcriteria) and epsilon waves in V1–V3 (major diagnostic criteria).

Mentions: Electrocardiography revealed a normal sinus rhythm, left axis deviation, and T-waveinversion in precordial leads from V2 to V6. Further, an epsilon wave in leads V1-V3(Figure 1) led to the suspicion of ARVC.Monitoring using a 24-h Holter electrocardiogram documented only occasional ventricularextrasystoles with left bundle branch block morphology and no significant cardiacarrhythmia. Further evaluation included cardiac magnetic resonance (CMR) imaging, whichrevealed right ventricular (RV) enlargement with an indexed end-diastolic volume of 110ml/m2 and mild dysfunction (ejection fraction = 44%). No signs of fattytissue infiltration were observed, but regional RV dyskinesia in the free wall andoutflow tract was identified (Figure 2A). LV wasmildly enlarged (90 ml/m2), and systolic function was at the lower limit ofnormal. Flow analysis revealed no shunts in the aorta and pulmonary artery.Subepicardial delayed enhancement was observed the lateral basal and middle segments ofLV as well as a small focal area of the RV free wall (Figure 2B). These findings suggested a diagnosis of ARVC with LVinvolvement.
