A prospective, single center, open-label, single arm, study to evaluate the safety and
technical performance of the CLAAS system for closure of the left atrial appendage.
The primary objective of the study is to evaluate feasibility of ICE as primary imaging
modality for device success in patients with non-valvular atrial fibrillation at increased
risk for stroke and systemic embolism who are recommended for oral anticoagulation (OAC)
therapy but have an appropriate rationale to seek a non-pharmacological alternative to OAC.
TEE will be used to confirm the ICE evaluation.
If you are confirmed eligible after full screening, you will be required to understand and sign the informed consent if you decide to enroll in the study. Once enrolled you may be asked to make scheduled visits over a period of time.
