The use of the Watchman left atrial appendage occlusion device (Boston Scientific Inc.) is becoming increasingly frequent in patients with atrial fibrillation. Cardiac computed tomography (CT) for device sizing pre-procedure can help facilitate more accurate device selection compared with transesophageal echo (TEE) alone. CT can also help identify minor lobes and trabeculations that may not be apparent on TEE. We report a series of three cases to highlight the utility of a novel application of CT-TEE fusion imaging to provide procedural guidance during Watchman implant and to assess for peri-device leak post-implant.
在心房颤动患者中，使用 Watchman 左心耳封堵装置（波士顿科学公司）的情况越来越频繁。与单独使用经食管超声心动图（TEE）相比，术前使用心脏计算机断层扫描（CT）进行器械大小测量有助于更准确地选择器械。CT 还可以帮助识别 TEE 上可能不明显的小裂片和小梁。我们报告了一系列三个病例，重点介绍了 CT-TEE 融合成像的新应用在 Watchman 植入过程中提供程序指导，并评估植入后器械周围漏的效用。
