Background: The optimal ablation strategy for persistent atrial fibrillation (PsAF) remains to be defined. We sought to compare very long-term outcomes between linear ablation and electrogram (EGM)-guided ablation for PsAF. Methods: In a retrospective analysis, long-term arrhythmia-free survival compared between two propensity-score matched cohorts, one with pulmonary vein isolation (PVI) and linear ablation including roof/mitral isthmus line (LINE-group, n=52) and one with PVI and EGM-guided ablation (EGM-group; n=52). Results: Overall, 99% of patients underwent successful PVI. Complete block following linear ablation was achieved for 94% of roof lines and 81% of mitral lines (both lines blocked in 75%). AF termination by EGM-guided ablation was accomplished in 40% of patients. Non-PV foci were targeted in 7 (13%) in the LINE-group and 5 (10%) patients in the EGM-group (p=0.76). During 100±28 months of follow-up, linear ablation was associated with superior arrhythmia-free survival after the initial and last procedure (1.8±0.9 procedures) compared with EGM-group (Logrank test: P=0.0001 and P=0.045, respectively). In multivariable analysis, longer AF duration and EGM-guided ablation remained as independent predictors of AAs recurrence. Conclusions: Linear ablation is a more effective complementary technique to PVI than EGM-guided ablation for PsAF ablation.

The article is devoted to the evaluation of the results of clinical application of penetrating radiofrequency ablation techniques on atrial myocardium.Material and Methods. A total of 298 patients with valvular heart disease complicated with atrial fibrillation were operated. All operations were performed under cardiopulmonary bypass and cardioplegia. The main group consisted of 198 patients who were operated using penetrating technique radiofrequency exposure. The control group consisted of 100 patients who underwent surgery with the use of «classical» monopolar radiofrequency-ablation technique. Both groups did not significantly differ in any parameter before surgery, but to increase confidence in the results, pseudo-randomization was performed using the Propensity score matching technique.Results. Patients with previous heart surgery were excluded during the selection of candidates for the procedure because of the presence of adhesions in the pericardium that did not allow good visualization of the left atrium, sufficient to perform the procedure. Penetrating technique had significantly higher efficiency compared to the «classic» technique in the early and long-term postoperative periods. The efficiency was 93% in the early postoperative period and 88% in the long term. The efficacy of «classical» monopolar procedure was lower: 86 and 68%, respectively.
