Abstract

Radiofrequency ablation (RFA) procedures require detailed mapping of atrial structure for patients with atrial fibrillation (AF). Identifying the spatial distribution and transmural properties of lesions in left atrium (LA) can provide helpful guidance to RFA treatment. We implement anatomical mapping by tracking sample-sites and capturing spectral signatures from near-infrared spectroscopy (NIRS) with an optical catheter. Using interpolation algorithm, we reconstruct atrial lesion maps of ex-vivo swine and human atriums, and evaluate the capability of NIRS to recognize spatial discontinuity of lesions.
