Fasciculoventricular bypass tract (FVBT) is rare. Concomitant presence of both conditions is well described in Danon disease. We report a case of familial HCM with FVBT linked to a heterozygous pathogenic variant, c.655G>C (p.Val219Leu), in the cardiac myosin binding protein C3 (MYBPC3) gene.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalCardiac magnetic resonanceDanon diseaseElectrocardiogramFasciculoventricular bypass tractHypertrophic cardiomyopathyImplantable cardioverter-defibrillatorLysosome-associated membrane protein 2Cardiac myosin binding protein C3Nonsustained ventricular tachycardiaWolff-Parkinson-White syndromeAccessory pathwayHypertrophic cardiomyopathyArticle
