This report concerns a patient with drug refractory supraventricular tachycardia due to the Wolff-Parkinson-White syndrome in association with a coronary sinus diverticulum. Division of the anomalous bypass tract was initially performed by an endocardial approach together with circumferential dissection of the neck of the diverticulum. This procedure failed to ablate the bypass tract that was only successfully divided when the superficial wall of the diverticulum was excised. This case illustrates the close association that exists between an anomalous atrioventricular bypass tract and a coronary sinus diverticulum, and the importance of dividing the superficial wall of the diverticulum as an integral part of the ablative procedure.
本报告涉及一名因 Wolff-Parkinson-White 综合征合并冠状静脉窦憩室而患有药物难治性室上性心动过速的患者。最初通过心内膜途径并对憩室颈部进行环形剥离来切断异常旁路。该操作未能消融旁路，只有在切除憩室浅壁时才成功切断旁路。该病例说明了异常房室旁路与冠状静脉窦憩室之间存在的密切关联，以及切除憩室浅壁作为消融手术不可或缺部分的重要性。
