Abstract

Objective: the totally thoracoscopic epicardial left atrial ablation for the treatment atrial fibrillation is a highly effective method even for long standing atrial fibrillation. This research shows results of thoracoscopic radiofrequency ablation atrial fibrillation.

Methods: from January 2015 to December 2017 72 patients were made totally thoracoscopic bilateral pulmonary vein isolation, roof and floor lesions and additional lines.64 (91,7%) patients were with persistent atrial fibrillation. 6 (8,3%) with paroxysmal. 9 (17%) were made earlier endocardial ablation of pulmonary veins. Was made periodic holter monitoring for determing freedom from atrial fibrillation.

Results: by December 2017 we have got 90-days results of freedom from atrial fibrillation from 61 patients with efficiency 87% . Rhythm of 12 patients were evaluated after 2 year(off antiarrhythmic drugs). In this group sinus rhythm was marked in 100% cases because of hybrid technology in two patients. Of all patients, hybrid treatment was used in 10 cases. In 8 cases was left atrial flutter and in 2 cases right atrial flutter. There was a pneumothorax in 2 cases such as complication of the surgery. There was no operative mortality, no myocardial infarction, and no stroke.

Conclusions: the totally thoracoscopic maze procedure is highly effective method in treatment atrial fibrillation with low operative risk.
