In this study, we propose to use optical coherence tomography to enable a direct visualization of
myocardium extending into the pulmonary vein (PV). The results showed that there are obvious differences
in the morphology of myocardium and fibrous tissue in the transition region of myocardial sleeve, which is
in agreement with the histological analysis. In addition, the myocardial area in transition point has three
layers in the depth of 1 mm, and the depth-resolved myocardial fiber show different orientation in the
different layers. This characteristic was applied for segmentation of the structures of myocardium extending
