Comparison of methods of left atrial appendage exclusion during surgical ablation of atrial fibrilation Abstract Atrial fibrillation is the most common heart arrhytmia affecting a significant part of the population over 60 years of age and it is an eminent source of cardio-embolic events. Leading source of intra-cardial thrombi is the left atrium of the heart, specifically the left atrial appendage. Randomised studies show significant reduction of cerebral ictus by the use of Warfarin in patients with atrial fibrillation, however the use of anticoagulation has its restrictions, side effects and contraindications. There are several surgical techniques of excision or exclusion of the left atrial auricle. This dissertation thesis is focusing on the comparison of the two most common surgical techniques - resection of the left atrial appendage using a stapler and the exclusion of the left auricle using a clip applied from the pericardial side. At the same time, we've set an objective of confirming the electrical insulation of the left atrial appendage as a significant source of fibrillation impulses when using the clip for the left appendage exclusion. In a group of 30 patients with atrial fibrillation and who underwent the surgical atrial fibrillation ablation using a clip or stapler amputation during complex...
