Mid-term outcomes of thoracoscopic and hybrid therapy of atrial fibrillation

Aim . To evaluate the efficacy and safety of thoracoscopic hybrid techniques in patients with various forms atrial fibrillation (AF). Methods The results ablation 87 AF were analyzed: 27 (31%) paroxysmal form, 15 (17%) - persistent, 45 (52%) long-term persistent form at follow-up 18.6±6.7 months. “Box-Lesion” treatments amputation left appendage (LAA) performed 69 (79.3%) patients, “Box Lesion” without LAA 12 (13.7%). When tachycardia was recorded for more than 30 seconds after a 3-month “blind” period, underwent catheter intervention. Results Freedom from arrhythmias group achieved 84% (21 25), 60% (9 15), 78% (32 41) given observation period. In structure postoperative tachycardia, recurrence 5 (6.25%), typical flutter (AFL) 3 (3.75%), atypical AFL 10 (12.5%). mean LA volume index stable sinus rhythm 64.6±11.3 ml/m2 versus 74.65±15.4 (Student’s t-test 0.53, p = 0.6). These At period 15.9±10.9 months, maintained (83.3%) patients. overall rate intra- complications 5.7%. Conclusion Thoracoscopic approaches are effective methods treatment.
