ABSTRACT
BACKGROUND:
Reflex syncope reduces quality of life and leads to fall-related injuries, with no highly effective treatment. In this context, cardioneuroablation (CNA) presents as a promising therapy for these patients.METHODS:
We searched PubMed, Embase and Cochrane Central for studies that evaluated safety and efficacy outcomes related to CNA procedures. Two reviewers independently performed study selection, data extraction and assessment of bias. Generalized linear mixed models was used. We performed a single-arm meta-analysis using R version 4.2.3.RESULTS:
A total of 25 studies comprising 871 patients were included. The mean follow-up ranged from 8 to 40 months. Mean age ranged from 32.9 to 53.9 years and 541 (62.1%) were female. The ablation target was biatrial in 302 patients (34%), left atrium only in 433 (49%), and right atrium only in 136 (15%). The freedom from syncope was 94% (95% confidence interval (CI) 90.13-97.00; P<0.01). Left and right atrial CNA was associated with a significant higher freedom from syncope (96.03%; 95% CI 93.13-97.73) than left atrial ablation only (94.61%; 95% CI 82.88-98.45) and right ablation only (84.53%; 95% CI 74.30-91.18). Peri-procedural adverse event occurred on 1.4% (95% CI 0.44- 4.50).CONCLUSION:
Our findings suggest that in patients with reflex syncope, CNA is a procedure associated with a significant reduction in syncope incidence and with low complication rates. Among the procedures used, both right and left ablation were more effective.
