Surgical treatment of atrial fibrillation (mechanisms – treatment – outcome)

ECG curve with atrial fibrillation and sinus rhythm, respectively

Atrial fibrillation is common in patients scheduled for cardiac surgery and it increases the mortality and morbidity.

Up to 50% of the patients undergoing mitral valve surgery have preoperative atrial fibrillation and concomitant surgery for atrial fibrillation is recommended in the current guidelines. It is performed by creation of isolating scar tissue lines in a certain pattern with different ablation methods.

We study the impact of these different ablation techniques on apoptosis (cell death), inflammatory response, atrial function and clinical outcome.
