In the LGE+ group, 11 patients had an ICD implanted for primary prevention without LV dilatation or reduction in LVEF; however, because of symptomatic episodes of nonsustained ventricular tachycardia (NSVT) (n = 7), asymptomatic NSVT with a family history of SCD (n = 1), or identification of clinically significant genetic variants with a family history of SCD (n = 3; lamin A/C, desmin, and desmoplakin) (Supplemental Table 1). This evidence concerns the gene DES and Schnyder corneal dystrophy.
