LV scar by LGE-CMR may refine arrhythmic risk stratification in ICD candidates; leaves open prospective validation for selection or mortality impact.
Does left ventricular scar burden assessed by LGE-CMR predict appropriate ICD therapy and all-cause mortality in patients undergoing ICD implantation?
Left ventricular scar burden quantified by LGE-CMR is strongly associated with spontaneous ventricular arrhythmias requiring ICD therapy, but not with all-cause mortality, suggesting its potential utility for improving patient selection for ICDs.
