ABSTRACT
BACKGROUND:
The safety and efficacy of a combined approach of catheter ablation (CA) and left atrial appendage occlusion (LAAO) compared to LAAO alone remain unknown.METHODS:
Patients with atrial fibrillation (AF) at increased stroke risk who underwent LAAO were divided into either combined (CA and LAAO) procedures or LAAO alone group. Propensity score matching was utilized to balance baseline characteristics. The primary endpoint of the study was a composite of death, thromboembolic events, major bleeding, heart failure (HF) rehospitalization, and major periprocedural complications.RESULTS:
A total of 707 AF patients who underwent LAAO were included. After 11 propensity score matching, 166 patients who underwent LAAO alone (n = 83) or the combined procedure (n = 83) were analyzed. Successful LAAO was achieved in all (100%) patients, with a low incidence of periprocedural complications in both groups (2.4% vs. 4.8%, LAAO vs. combined, p = 0.68). The incidence of peri-device leak post-LAAO was significantly higher in the combined group (25.3% vs. 43.4%, p = 0.01). After a median follow-up of 2 years, there were no significant differences in the rates of the primary composite endpoint between the two strategies (22.2% vs. 14.3%, HR 1.24 [95% CI 0.51-2.97], p = 0.63). However, the rate of HF rehospitalization was significantly lower in the combined group (19.6% vs. 3.6%, HR 4.89 [95% CI 1.50-15.97], p = 0.024).CONCLUSIONS:
Combining CA and LAAO in a "one-stop" approach is safe and brings additional benefits in relieving symptoms of heart failure, although peri-device leak was more common compared to LAAO alone.
