“…Interestingly, in this study the total volume of LGE was not associated with ECG changes such as QRS duration and T‐wave inversion, whereas the location of LGE was significantly associated with ECG changes. These findings are in contrast with a previous report showing QRS duration was correlated with the extent and spread of delayed hyperenhancement, but not with the presence of delayed hyperenhancement at the interventricular septum 25. In accordance with our study, Dumont et al reported that conduction disturbance in HCM was associated with septal delayed hyperenhancement 15.…”

“…Surprisingly, the transmural extent of the delayed enhancement and the percentage of LV myocardium with delayed enhancement were not associated with ventricular arrhythmias. Satoh and co-workers ( 91 ) have demonstrated that the presence of delayed enhancement is not only correlated with prevalence of ventricular tachycardia on Holter monitoring, but is also associated with higher New York Heart Association functional class, impaired global LV function, conductance disturbance, abnormal Q waves, and giant T waves.…”

“…It has been shown that patients with HCM and any degree of delayed enhancement have a 7-fold higher risk for nonsustained ventricular tachycardia on Holter monitoring compared with patients without evidence of delayed enhancement. 24 In 2009, Satoh et al 25 demonstrated that the presence of delayed enhancement is not only related to ventricular arrhythmias but is also associated with a higher New York Heart Association functional class, impaired global LV function, conductance disturbance, abnormal Q waves, and giant T waves. Bruder et al 26 demonstrated that the presence of a scar detected by delayed enhancement in MRI is an independent predictor of all-cause mortality as well as of cardiac mortality in HCM patients (odds ratio of 5.47 for all-cause and 8.01 for cardiac mortality) and that the presence of delayed enhancement could be useful for noninvasive risk stratification in asymptomatic and mildly symptomatic HCM patients.…”
