Catheter ablation for persistent atrial fibrillation after acute decompensated heart failure Attack: Earlier is Better?

ABSTRACT:

Background

Acute decompensated heart failure (ADHF) is often accompanied by persistent atrial fibrillation (AF). However, the optimal timing for RFCA in patients with persistent AF and ADHF is still uncertain.

Objectives

The aim of this observational cohort study is to investigate the safety and efficacy of early RFCA in patients with persistent AF after ADHF attack.

Methods

Patients with persistent AF and ADHF who underwent early RFCA as soon as the ADHF symptoms were initially controlled (Early group, n = 63) and those who received elective procedures after a transitional period (Elective group, n = 67) were investigated. After 1:1 propensity score matching, 50 matched pairs were analyzed.

Results

The overall procedural complication rates were similar (Early group: 6.0 %, n = 3; Elective group: 6.0 %, n = 3; P = 1.000). Patients in the early group had significantly less HF rehospitalization than the elective group during the 1-year post-procedure follow-up period (Mantel-Cox test: P = 0.036; HR: 0.369; 95 %CI: 0.145-0.938), though AF recurrence showed no difference (Mantel-Cox test: P = 0.645; HR: 1.204; 95 %CI: 0.547-2.648). A 90-day rehospitalization rate was significantly higher in the transitional period in the elective group, compared with patients who already received early RFCA (Elective group: 13, 26.0 %; Early group: 2, 4.0 %; P = 0.002).

Conclusions

Early RFCA therapy for persistent AF after ADHF attack was safe and effective. Patients who received early RFCA therapy had significantly less HF rehospitalization in the 1-year post-procedure follow-up period. On the other hand, the elective procedure was accompanied by a higher risk of HF rehospitalization during the waiting period.
