Background: Catheter ablation has emerged as an effective treatment option for atrial fibrillation (AF) in the general population. However, limited data exist on the outcomes of catheter ablation in patients infected with the Human Immunodeficiency Virus (HIV+) with concomitant AF.
Objectives: This systematic review and single arm meta-analysis aims to comprehensively evaluate the literature on catheter ablation approach and outcome in HIV+ patients with AF.
Methods: A systematic search of PubMed, Embase, and Cochrane Central Register of Controlled Trials was conducted following PRISMA guidelines.Studies meeting the intervention of catheter ablation for AF in HIV+ patients, using radiofrequency, cryoballoon, or pulsed field ablation techniques, were included and data were collected and synthesized using proportion meta-analysis techniques. Statistical analysis was carried out using R software.
Results: Three studies met the inclusion criteria, involving 89 HIV+ patients, with an average age of 51.5 years, of whom 83.1% were men, undergoing catheter ablation. Two studies performed received isolation of the pulmonary vein (PV) + posterior wall and superior vena cava. And one study evaluated only the isolation of the pulmonary veins. Of these patients, 43.8% had paroxysmal AF and 56.1% had persistent AF. In two studies reporting freedom from atrial arrhythmias, all patients (62) experienced recurrence of atrial arrhythmias within 5 years of follow-up. Freedom from repeat ablation was 6.26% (Figure 1A). The rate of Pulmonary Vein Trigger was 31.28% (Figure 1B), while the rate of Non-Pulmonary Vein Trigger (non-PV) was 76.64% (Figure 1C).
Conclusion: In this systematic review and meta-analysis assessing outcomes of ablation in HIV patients with AF, we observed a similar prevalence of paroxysmal and persistent AF. Furthermore, contrary to the non-HIV+ patients, a high incidence of non-pulmonary vein triggers of AF was noted in this population.
