Researchers investigated whether adding a specific linear ablation to standard pulmonary vein isolation helps patients with persistent atrial fibrillation. The study included 228 patients who received either the combined Left Atrial Posterior Wall Linear Ablation and Pulmonary Vein Isolation (LAPVI) or PVI alone. Participants were followed for up to two years to see how well their heart rhythms were maintained and how often they needed medication.
At the two-year mark, 74.77% of patients in the combined LAPVI group maintained a normal sinus rhythm, compared to 54.7% in the PVI-only group. The rate of atrial fibrillation recurrence was also lower in the combined group, with fewer patients needing antiarrhythmic drugs at every follow-up interval. These differences were statistically significant, suggesting the added procedure offers benefits for rhythm control.
The study did not report specific safety concerns, adverse events, or discontinuations related to the procedure. While the results are encouraging for long-term rhythm stability, readers should note that the study was not designed to prove long-term safety beyond the two-year follow-up. Patients considering this procedure should discuss these findings with their cardiologist to understand how they apply to their specific situation.
