Follow-up
All patients were followed in our dedicated LAA clinic, at 6 weeks, 6-months, 1-year, and 2-years after the procedure. During the follow-up visits, clinical status and ECG were recorded. A TEE was performed at 45-60 days post procedure then repeated at 1-year follow-up to assess persistence of correct sealing and PASS criteria and exclude any complication. If a TEE was contraindicated, a standard TTE was performed.
