Abstract
- Background: Atrial fibrillation (AF) is the most common arrhythmia diagnosed in humans and therefore causes a high socioeconomic burden. The Cox-Maze IV procedure is the gold standard treatment for atrial fibrillation. Minimally invasive surgery for the treatment of AF is also promising. Objectives: Our aim is to evaluate the feasibility, safety, and immediate plus medium-term results of concomitant AF ablation therapy in patients undergoing minimally invasive valve surgery through right-sided minithoracotomy. Patients and Methods: Retrospective data were collected from January 2012 to December 2013. Seventy-five consecutive patients underwent radiofrequency ablation during valve surgery through a right-sided minithoracotomy. Results: All 75 patients underwent radiofrequency ablation. The pulmonary vein was isolated in 6 (8%) by encircling the left and right pulmonary veins. In 9 (12%) patients, endocardial box lesions were created using a monopolar probe, while in 47 (62.7%), epicardial box lesions were produced with a monopolar probe. Thirteen (17.3%) patients received a box lesion created with a bipolar probe. Finally, in 22 (293%) patients, a line of lesions was produced leading up to the posterior mitral annulus. Only 1 (1.3%) perioperative death was observed. At discharge, 43 (57.3%) patients were in sinus rhythm and 30 (40%) were in AF. After a mean follow-up of 21.6 ± 10.1 months, 46 patients (63%) were in a stable sinus rhythm and 27 were in (37%) in AF; 26 (56.5%) patients were free from antiarrhythmic therapy, while 19 (42.2%) were still taking at least one drug. Conclusions: We can conclude that treatment of AF using a right-sided minithoracotomy approach and RF energy in patients undergoing cardiac surgery for various valve diseases is feasible, safe, and reproducible.
