What is the impact of ICD artifact burden on LGE-CMRI in patients undergoing VT ablation?
Current LGE-CMRI protocols produce significant ICD artifacts affecting >50% of the LV myocardium, limiting their utility for image-guided VT ablation.
Current clinical LGE-CMRI scar imaging protocols produce ICD artifacts that affect >50% of the LV myocardium and correlate with the ICD-heart distance. This significantly limits the application of CMRI for image-guided VT ablation.
