2.7 Post-procedural management and follow-up
All patients underwent transthoracic echocardiography to rule out pericardial effusion the following day. OAT was administered for at least 45 days and 2 months in patients with isolated LAAC and those with combined procedures, respectively. This was followed by aspirin and clopidogrel for 6 months and aspirin or clopidogrel lifelong. At 45-day, 6-month and 12-month follow-up, TEE was performed to evaluate the device position, residual flow and thrombus formation on the device surface. Routine electrocardiogram and 24h Holter monitoring were examined at 3 and 6-months post procedure, and 7-day Holter monitoring was performed at 12months post procedure.
