Of these patients, 29 (60.4%) satisfied major non-imaging TFC criteria and 19 (39.6%) satisfied minor non-imaging TFC criteria; 16 (33.3%) patients had a first-degree relative with confirmed ARVC, 8 (16.7%) had a first-degree relative with premature sudden death due to suspected ARVC, 4 (8.3%) had a pathogenic mutation linked to ARVC (PKP2), 13 (27.1%) had ventricular tachycardia with left bundle branch morphology and 11 (22.9%) had more than 500 ventricular extra-systoles in a 24-h period. Here, PKP2 is linked to Arrhythmogenic right ventricular dysplasia.
