Abstract

Atrial fibrillation (AF) can be treated by catheter abla-/ntion to electrically isolate t/nhe pulmonary veins (PVs)/nfrom the left atrial (LA) body. To guide the procedure,/nan anatomical representation of the LA is usually visua-/nlised by an electroanatomical mapping system. As a/nfollow-up, late gadolinium enhancement MR sequences/ncan be obtained to assess the extent of ablation delivery./nHowever, visual analysis and quantification is time-/nconsuming with poor reproducibility. Unfold maps/noffer advantages over 3D surfaces for visualisation of/nimaging information while providing a common reference/nspace for inter-subject comparison. We have developed a/nmethod to automatically map multimodal information/nonto a standardised unfold map (SUM) of the LA. We/nuse the SUMs to compare force and scar information/nfrom the same patient.
