Research Article: Long-term outcome of patients with atrial fibrillation and heart failure with preserved ejection fraction after combined radiofrequency catheter ablation and left atrial appendage closure
Abstract:
In patients with heart failure with preserved ejection fraction (HFpEF), further investigation of the safety and long-term efficacy of combined radiofrequency catheter ablation and left atrial appendage closure (RF?+?LAAC) in patients with HFpEF is warranted.
In this retrospective study, we aimed to evaluate the outcome of RF?+?LAAC in patients with AF and HFpEF, compared to radiofrequency catheter ablation (RF) alone. 331 patients with AF and chronic HFpEF were divided into two groups: RF?+?LAAC ( n =?196) and RF ( n =?135). After 1:1 propensity score matching (PSM), 96 matched pairs were enrolled in further analysis. HF rehospitalization, ischemic stroke/transient ischemic attack (TIA), and major bleeding events were assessed over 24 months. Kaplan–Meier analyses were used to compare outcomes.
The RF?+?LAAC group demonstrated comparable procedural complication rates to RF alone (5.2% vs. 4.2%, p =?0.733). The risks of ischemic stroke/TIA (ARR=4.95%, HR?=?0.096, 95%CI:0.012–0.753, p =?0.026) and major bleeding events (ARR=3.91%, HR?=?0.120, 95%CI: 0.015–0.957, p =?0.045) were significantly lower in RF?+?LAAC group vs. RF alone, while HF rehospitalization was similar between the two groups (ARR=?0.56%, HR?=?1.356, 95%CI: 0.303–6.059, p =?0.690).
In patients with AF and HFpEF, combined RF?+?LAAC was associated with lower risks of ischemic stroke/TIA and major bleeding, without an observed increase in HF rehospitalization, compared with RF alone.
