Key result
OCT visualizes microscopic pulmonary venoatrial junction architecture including myocardial sleeves and fibrosis.
Why the study?
Imaging guidance with optical coherence tomography could improve AF ablation outcomes by providing detailed structural information of pulmonary veins, which are critical ablation targets.
Does optical coherence tomography (OCT) accurately identify structural features of the pulmonary venoatrial junction compared to histology in post-mortem human hearts?

OCT can identify detailed tissue architecture of the pulmonary venoatrial junction, potentially improving understanding of the AF structural substrate and guiding ablation procedures.
Imaging guidance provided by optical coherence tomography (OCT) could improve the outcomes of atrial fibrillation (AF) ablation by providing detailed structural information of the pulmonary veins, which are critical targets during ablation. In this study, stitched volumetric OCT images of venoatrial junctions from post-mortem human hearts were acquired and compared to histology. Image features corresponding to venous media and myocardial sleeves, as well as fiber orientation and fibrosis, were identified and found to vary between veins. Imaging of detailed tissue architecture could improve understanding of the AF structural substrate within the pulmonary veins and assist the guidance of ablation procedures.

Lye et al. (2019) studied Atrial fibrillation. Optical coherence tomography (OCT) vs. Histology was evaluated on Identification of image features corresponding to venous media, myocardial sleeves, fiber orientation, and fibrosis. Optical coherence tomography successfully identified detailed tissue architecture of the pulmonary venoatrial junction, including venous media, myocardial sleeves, fiber orientation, and fibrosis.
