| Popis: | Arrhythmogenic right ventricular cardiomyopathy (ARVC) is pathologically characterized by fibrofatty replacements.1 It is reported that the subtricuspid/peritricuspid area and the left ventricular inferolateral wall may be the only affected regions in the early stages of ARVC.2 This lipomatous or lipofibromatous composition causes delayed excitation. This late conduction through diseased myocardium is described as an epsilon wave, which is included in the revised Task Force diagnostic criteria.3 Herein, we report a case of ARVC with epsilon wave, in which radiofrequency catheter ablation (RFCA) on left ventricular outflow tract (LVOT) eliminated the epsilon wave. |
