GW27-e0209 Application of echocardiographic three-dimensional printed left atrial appendage model to guide transcatheter left atrial appendage occlusion

This study aimed to determine the feasibility of three dimensional (3D) printed left atrial appendage (LAA) models based on 3D transesophageal echocardiography (3D TEE) data and its application value in the interventional LAA closure. Eighteen patients who had interventional LAA occlusion underwent
