Asymmetric septal hypertrophic cardiomyopathy with a preserved ejection fraction is the most common type of hypertrophic cardiomyopathy. In this condition, the mass % of myocardial scarring on LGE MRI is the significant parameter related to ventricular tachyarrhythmia and the subsequent invasive treatments for it among clinical and MRI parameters. Quantification of the mass % of myocardial scarring is recommended to confirm the relationship between LGE MRI and ventricular tachyarrhythmia, which should be treated by invasive treatments, in asymmetric septal hypertrophic cardiomyopathy with a preserved ejection fraction.
