Computed tomography measurement for left atrial appendage closure.

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Percutaneous left atrial appendage closure (LAAC) is increasingly used for non-valvular atrial fibrillation.
• While safe, LAAC benefits from enhanced preoperative planning and postoperative assessment.

Purpose of the Study:

• To review the practical utility of computed tomography (CT) in the pre- and post-procedural management of LAAC.
• To highlight CT's role in optimizing treatment strategies and patient outcomes.

Main Methods:

• Review of current literature and clinical practices regarding CT utilization in LAAC.
• Analysis of CT's contribution to anatomical assessment, risk prediction, and device selection.
• Evaluation of CT for postoperative monitoring of device-related thrombus and peri-device leaks.

Main Results:

• Preoperative CT accurately predicts intervention risks based on left atrial appendage (LAA) anatomy.
• CT guides optimal device selection, sheath type, and septal puncture site.
• Postoperative CT enables less invasive monitoring for complications like device-related thrombus and leaks.

Conclusions:

• Computed tomography is a valuable tool for comprehensive pre- and post-procedural management in LAAC.
• Integrating CT into LAAC workflows improves procedural safety, efficacy, and patient monitoring.
• CT facilitates personalized treatment strategies and enhances the overall success of LAAC.
