ObjectiveTo summarize clinical advantages and outcomes of minimally invasive mitral valve replacement (MVR) combined with atrial fibrillation (AF) radiofrequency ablation via right minithoracotomy. MethodsEight patients with mitral valve disease and AF who received surgical therapy in the First Hospital of China Medical University between October 2009 and October 2012 were included in the study. There were 4 males and 4 females with their age of 34-67 (52.4±17.5) years. All the patients underwent minimally invasive MVR combined with AF radiofrequency ablation via right minithoracotomy. Clinical outcomes were summarized. ResultsThere was no in-hospital death or conversion to conventional sternotomy in this group. Two patients received biological valve replacement and 6 patients received mechanical prosthesis. Operation time was 207.9±18.1 minutes, cardiopulmonary bypass time was 81.7±23.9 minutes, and chest drainage amount was 126.7±34.5 ml. AF recurred in 1 patient on the 3rd postoperative day. All the patients were in sinus rhythm at discharge. These patients were followed up for 18.3±7.4 months. During follow-up, 1 patient had AF recurrence. Seven patients were in NYHA class Ⅰ, and 1 patients was in NYHA class Ⅱ. ConclusionMinimally invasive MVR combined with AF radiofrequency ablation via right minithoracotomy can achieve satisfactory clinical results and esthetic appearance, and is a good choice for patients with mitral valve disease and AF.
ObjectiveTo conclude the outcomes of mitral valve repair for mitral bileaflet prolapse. MethodsWe retrospectively analyzed the clinical data of 14 patients with mitral bileaflet prolapse in our hospital between June 2010 and March 2013. There were 10 males and 4 females with at age of 46.9±12.0 years. We used one technique in 4 patients, two techniques in 9 patients, three techniques in 1 patient. ResultsMean follow-up time was 13.1±7.2 months. There was no perioperative death. No reoperation occurred. No or trace mitral regurgitation (MR) was found in 13 patients. Slight MR was found in one patient. ConclusionThe early metaphase results of mitral valve repair for mitral bileaflet prolapse are satisfactory if the appropriate surgery method is chosen.
