RESUMEN
INTRODUCTION: Robotic mitral valve surgery is a challenging issue, particularly in patients who are not suitable for aortic cross-clamping. In this study, we aimed to determine the feasibility and benefits of robotic, beating heart mitral valve surgery. METHODS: From February 2019 to February 2022, 17 patients underwent robotic beating heart mitral valve surgery. Fourteen of the patients had previous cardiac surgery. The mean age was 58.1 ± 10.3. Dense periaortic adhesions, heavily calcified aorta, and low ejection fraction were retained as indications for beating heart surgery. RESULTS: Mitral valve replacement was performed in 14 patients. Mitral ring annuloplasty was performed in two patients with low ejection fraction (EF). A severe paravalvular leak was repaired in one patient. Additional tricuspid annuloplasties were performed in three patients. Cardiopulmonary bypass time were 185.6 ± 55 min. There were no cases of conversion to sternotomy or thoracotomy. No cerebrovascular event occurred in the follow-up. One patient died as a result of secondary hepatorenal syndrome and multiorgan failure. CONCLUSIONS: Robotic beating heart mitral valve surgery is a feasible and effective technique with favorable early and mid-term results, especially in patients who are not suitable for aortic cross-clamping, secondary to periaortic adhesions, severe aortic calcifications, and low ejection fraction.
