在预激综合征（WPW）中作为旁路的心肌束通常是微小的组织，因此阐明房室（AV）心肌连接的罪魁祸首组织学需要仔细的AV连接连续切片。我们对一例84岁男性患者进行了房室旁道心肌连接的尸检，该患者在手术冷冻消融治疗预激综合征20年后死于肺炎。连续组织切片的三维重建图像显示，冷冻消融瘢痕附近的心房和心室心肌之间存在附件AV连接。残余心肌桥宽4mm，由多条不连续的心肌纤维组成。该病例提供了肯特残余束的组织学形态学可视化信息。(C)2018爱思唯尔公司All rights reserved.
Myocardial bundles working as accessory pathways in Wolff-Parkinson-White (WPW) syndrome are generally tiny tissues, so elucidating the culprit histology of atrioventricular (AV) myocardial connections requires careful serial sectioning of the AV junction. We performed a postmortem examination of accessory AV myocardial connections in an 84-year-old man who died from pneumonia 20 years after surgical cryoablation for WPW syndrome. Three-dimensional reconstruction images of serial histologic sections revealed accessory AV connections between the atrial and ventricular myocardium in the vicinity of the cryoablation scar. The remnant myocardial bridge was 4 mm wide and made up of multiple discontinuous fibers. This case was informative in that it provided for visualization of the histologic morphology of a remnant bundle of Kent. (C) 2018 Elsevier Inc. All rights reserved.
