Despite good progress in the management of patients with atrial fibrillation (AF), this arrhythmia remains one of the major causes of stroke, heart failure, sudden death, and cardiovascular morbidity in the world. Furthermore, the number of patients with AF is predicted to rise steply in the coming years. Even if the amount of antiarrhythmic drugs (AAD) is constantly increasing, there is a group of patients who has AF, resistant to AAD therapy. In such cases they are being offered alternative minimally invasive procedures, such as catheter or thoracoscopic ablation. With the discovery that AF often is initiated and maintained by electrical instability inside and around the pulmonary veins (PV) catheter and thoracoscopic ablation are now widely accepted invasive strategies to cure AF. Even though the results of both of the procedures are very promising in treating patients with paroxysmal AF, the decision making process, which approach should be used in patients with persistant or LSPAF, is still very controversial. According to 2016 ESC Guidelines for the management of atrial fibrillation developed in collaboration with EACTS, catheter or surgical ablation should be considered in patients with symptomatic persistent or long-standing persistent (LSP) AF refractory to AAD therapy to improve symptoms, considering patient choice, benefit and risk, supported by an AF Heart Team (IIaC). Since, there is no actual evidence base, which approach is more effective and save in patients with persistant and LSP AF, the aim of the investigator's study is to evaluate the results of both of the approaches in such group of patients.
