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.
