Figure legendsFigure 1. Representative case of DHF after AF ablation
In this patient, DHF occurred 12 hours after RFCA for persistent AF.
Intensive care, diuretics, and nitrates were needed for management.
AF: atrial fibrillation, RFCA: radiofrequency catheter ablation, DHF:
decompensated heart failureFigure 2. Time course and heart rate from the procedure to DHF
DHF occurred in 32 (3%) of all patients, and 10 (31%) patients
developed early recurrence of AF before DHF.
AF: atrial fibrillation, DHF: decompensated heart failureFigure 3. Subgroup analysis of Δheart rate
Persistent AF, past history of symptomatic heart failure, low LVEF,
beta-blocker usage and low-voltage areas were significantly associated
with lower Δheart rate
AF: atrial fibrillation, LVEF: left ventricular ejection fractionFigure 4. Freedom from AF recurrence and late phase DHF
requiring re-hospitalization in patients with and without DHF
Freedom from AF recurrence was similar between patients with and without
DHF. In contrast, freedom from late phase DHF requiring
re-hospitalization was significantly lower in patients with DHF than in
those without.
