Authors

Discussion

Gap detection on imaging may flag post-PVI recurrence risk; leaves open need for prospective validation before practice change.

Population

50 atrial fibrillation (AF) patients who underwent pulmonary vein isolation (PVI) with radiofrequency ablation, plus synthetic data

Intervention

Semi-automatic identification and quantification of ablation gaps using minimum path search and Relative Gap Measure (RGM) on LGE-CMR

Outcome

Quantification of ablation gaps (Relative Gap Measure)surrogate

A novel semi-automatic method using LGE-CMR can quantify ablation gaps after PVI, revealing that the left superior PV is most prone to gaps.

Nuñez‐Garcia et al. (2018) studied this question.
