Abstrakt: Objective: Atrial fibrillation (AF) is the most common arrhythmia, which is also associated with mitral valve disease. Surgical ablation is still known to be an important procedure in restoring sinus rhythm (SR) concomitant with mitral valve surgery (MVS). In this study, we aimed to pres-ent our early- and mid-term result of AF cryoablation during robotic MVS.
Methods: Between November 2014 and January 2020, total 34 patients who underwent robotic MVS with concomitant AF ablation were ret-rospectively analyzed. Ten patients had a <1 year AF history, 14 had 1-5 years, and 10 had >5 years. The primary end point of the study was postoperative AF recurrence.
Results: Total 32 and 2 patients underwent mitral valve replacement and mitral valve repair, respectively. Mean aortic cross-clamp and cardio-pulmonary bypass times were 141.8±32.1 min and 196±25.6 min, respectively. The SR was restored with the removal of cross-clamp and cardiac junctional rhythm was observed in 29 (85.3%) and 5 (14.7%) patients, respectively. Two in-hospital deaths secondary to low cardiac output and hepatorenal failure were recorded. Among the rest, 24 (75%) patients were in SR, 6 (18.75%) in AF, and 2 (6.25%) in paced rhythm at discharge.
Conclusion: Robotic cryoablation of AF during MVS is a feasible method with favorable early- and mid-term results.
