Postablation Follow-Up
During a mean follow-up period of 32.5±22.9 months (4.0 to 63.1) after the index procedure, five patients were free from AT/AF without anti-arrhythmic drugs.
One patient (Case 3) had a recurrence as AT 6 months after the first procedure. In the second procedure, we confirmed the reconnection of the 4 PVs and rapid firing originating from the right PV. ATP administration following re-isolation of all PVs never induced AF. The patient was free from atrial tachyarrhythmia after the second procedure.
In another patient (Case 2), remote monitoring of ICD documented a few episodes of AF 11 months after the index (i.e., second) procedure. The patient was asymptomatic because all episodes occurred at mid-night or early morning and terminated within one to two minutes. We did not perform the third procedure; however, there had been no AF episode for over four years since these AF episodes.
