TABLE 4.

Comparison of Other Imaging Artifact Burden on Late Gadolinium Enhancement (LGE) Sequences by Implantable Cardioverter-Defibrillator (ICD) Subtype

	WB Other Artifact (%)		Standard LGE Other Artifact (%)
	Median (IQR)	N	Median (IQR)	N	P-value
TV-ICD	0 (0–18)a,c	48	7 (0–21)d,f	47	0.43
CRT-D	23 (8–33)b,c	48	24 (10–33)e,f	14	0.73
S-ICD	0 (0–10)a,b	17	0 (0–7)d,e	7	0.71

As in Table 2, other non-device-related artifact (motion or wrap) is expressed as a percentage of short-axis slices affected by artifact out of the total number of short-axis slices.

TV-ICD = transvenous ICD; CRT-D = cardiac resynchronization therapy device; S-ICD = subcutaneous ICD; IQR = interquartile range; WB = wideband.

^aS-ICD versus TV-ICD for WB: P < 0.001.

^bS-ICD versus CRT-D for WB: P = 0.07.

^cTV-ICD versus CRT-D for WB: P = 0.10.

^dS-ICD versus TV-ICD for Standard LGE: P = 0.004.

^eS-ICD versus CRT-D for Standard LGE: P = 0.02.

^fTV-ICD versus CRT-D for Standard LGE: P = 0.19.
