Intracardiac Versus Transesophageal Echocardiographic Guidance for Left Atrial Appendage Occlusion
Trial Parameters
Brief Summary
This single-center, prospective, randomized study will evaluate the safety and feasibility of Intracardiac echocardiography (ICE)-guided Left atrial appendage closure (LAAC) when compared to the traditional Transesophageal echocardiography (TEE) approach.
Eligibility Criteria
Inclusion Criteria: 1. Patients diagnosed for non-valvular atrial fibrillation with documented paroxysmal, persistent, or permanent NVAF. 2.

Patient suitable for OAC with warfarin or DOAC and have appropriate rationale to seek a nonpharmacologic alternative to long-term OAC, meeting commercial LAAO criteria indications. 4. Can undergo appropriate pre-procedural imaging with Computed tomography (CT) or transesophageal echocardiography (TEE). 5. Patient should be able to comply with the protocol. 6. Provide written informed consent before study participation. 7. Ages 18 and above Exclusion Criteria 1\) A patient will be ineligible for inclusion in this study if he or she meets any of the following criteria: 1.
