Follow-up
After the procedure, anticoagulant drugs including DOAC or warfarin were
used for three months. All patients underwent echocardiography at 1, 3,
and 6 months after the procedure. ECG and 24-hour ECG monitoring were
performed whenever the patient had symptoms suggestive of arrhythmia.
The 36F quality-of-life index was measured in all patients before and
six months after the procedure.
