BACKGROUND: Few studies have reported the outcomes of two-incision total thoracoscopic mitral valve repair (MVr) and concomitant radiofrequency atrial fibrillation ablation (RAFA) in patients with rheumatic mitral valve disease and atrial fibrillation (AF).
METHODS: We retrospectively analyzed 43 consecutive patients who underwent MVr and RAFA through two-incision total thoracoscopic technique from October 2018 to June 2022. We collected data on baseline characteristics, perioperative outcomes, and early-term results.
RESULTS: The mean age was 55.67 ± 7.64 years and 29 (67.4%) patients had New York Heart Association (NYHA) class III or IV. The mean cardiopulmonary bypass (CPB) time was 115.56 ± 8.53 min and aortic clamping time was 81.42 ± 7.54 min. There were no in-hospital deaths or strokes. The mean preoperative mitral valve orifice area (MVOA) was 0.95 (0.84-1.16) cm2 and increased to 2.56 (2.41-2.87) cm2 at discharge and 2.54 (2.44-2.76) cm2 at 3 months after surgery (P < .001). At discharge, 32 (74.4%) patients were in sinus rhythm, 7 (20.9%) were in junctional or atrial flutter rhythm, and 4 (9.3%) remained in AF. At 6 months, 35 (81.4%) patients were in sinus rhythm, 5 (11.63%) were in junctional or atrial flutter rhythm, and 3 (4.7%) were in AF.
CONCLUSIONS: Two-incision total thoracoscopic MVr and RAFA is a safe and effective procedure that can improve the MVOA and promote conversion of AF to sinus rhythm in patients with rheumatic mitral valve disease and AF. Further studies with larger sample size and longer follow-up are needed to confirm the long-term benefits of this approach.
