Abstract
Ablation and visualization systems and methods to access quality of contact between a catheter and tissue are provided. In some embodiments, a method for monitoring tissue ablation of the present disclosure comprises advancing a distal tip of an ablation catheter to a tissue in need of ablation; illuminating the tissue with UV light to excite NADH in the tissue, wherein the tissue is illuminated in a radial direction, an axial direction, or both; determining from a level of NADH fluorescence in the illuminated tissue when the distal tip of the catheter is in contact with the tissue; and delivering ablation energy to the tissue to form a lesion in the tissue.
