CT-Based Preplanning Allows Abstaining from Intraprocedural TEE during Interventional Closure of the LAA in Patients with Atrial Fibrillation.

Objectives: The aim of this study was to determine whether the application of a CT-based preplanning algorithm might allow abstaining from TEE during LAAC.

Background: LAAC is an established treatment alternative for patients with atrial fibrillation. Today, most LAAC procedures are guided by TEE, which, however, leads to the need for patient sedation and might even cause direct harm to the patient.
