This study aimed to determine the relationship between the extent and the location of late gadolinium enhancement (LGE) and ventricular tachyarrhythmia or implantable cardioverter defibrillator (ICD) in hypertrophic cardiomyopathy (HCM).


We enrolled 115 patients with HCM and LGE. The location of LGE was divided into septal and nonseptal segments. Clinical backgrounds and LGE were compared in patients between with and without the arrhythmia or consequent ICD installation.


There were significant differences in the number of risk markers, left ventricular ejection fraction, extent of global LGE, and extent of nonseptal LGE between the groups (P < 0.01). Multivariate analysis revealed that the number of risk markers and extent of nonseptal LGE contributed to ventricular tachyarrhythmia or ICD installation (P < 0.01).


The nonseptal LGE is related to ventricular tachyarrhythmia or ICD installation. We should be vigilant for nonseptal LGE when applying LGE to risk stratification for HCM.
