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.
