Mean age was 25.8 years (4 to 75), and sinus rhythm was present in 63%. The functional classification used was type I, normal leaflet motion, 71 patients (7%); type II, prolapsed leaflet, 311 patients (33%); and type III, restricted leaflet motion, 345 patients (36%). The combined lesion of prolapse of the anterior leaflet and restriction of the posterior was present in 224 patients (24%). Surgical techniques used were implantation of a prosthetic ring in 95%, shortening of the chords and leaflet enlargement with autologous pericardium, and commissurotomy. Hospital mortality rate was 2%. The mean follow-up was 12 years (maximum, 29 years): 8618 patients per year. Actuarial survival was 89 19% at 10 years and 82 18% at 20 years. The rate of thromboembolic events was 0.4% patients per year (33 events), with 3 deaths. Freedom from reoperation was 82 19% at 10 years and 55 25% at 20 years. The main cause (83%) of reoperation was progressive fibrosis of the MV. The actuarial rate of reoperation was 2% patients per year and was correlated to the degree of preoperative fibrosis.,功能分级型，瓣叶活动正常的患者有71例（7%）；型，瓣叶脱垂者311例（33%）；型，瓣叶活动受限者345例（36%）。二尖瓣前叶脱垂同时伴后叶受限的患者共224例（24%）。,随访12年（最长29年）：每年8618例患者。10年的实际存活率为8919%，20年为8218%。每年血栓栓塞事件的发生率为0.4%（33例），其中3例患者死亡。10年内无需再次手术的患者占8219%，20年为5525%。再次手术的主要原因为二尖瓣进行性纤维化,%,总修补人数 = 201 例患者,二尖瓣修补联合主动脉瓣置换治疗风湿性心脏病 Huynh-Quang Tri Ho, MD, Van-Phan Nguyen, MD, Kim-Phuong Phan, MD, Nguyen-Vinh Pham, PhD Heart Institute, Ho Chi Minh City, Vietnam,MS 30% MR 37% Mixed 33%,死亡率 修补 1.4 % 置换 0.7 %,1组中9年内无需再次二尖瓣手术者占84.2 13% ，2组为 92 7.4% (log-rank test: p = 0.42),戊二醛处理的自体心包补片瓣膜修补术治疗复杂性二尖瓣病变 Choi-Keung Ng, MD, Joachim Nesser, MD, Christian Punzengruber, MD, Otmar Pachinger, MD, Johannes Auer, MD, Herbert Franke, MD, and Peter Hartl, MD,Ann Thorac Surg 2001;71:7885,63例患者超过10年 院内死亡率为 5 年内无再次手术 95 %,技术 扩大50 % 戊二醛0.625% - 30 分钟 6/0 或 7/0 Gore-Tex 缝线,风湿性二尖瓣修补术后无再次手术患者的存活率,风湿性 MR 10 年无再次手术的存活率 85 90 % 风湿性联合瓣膜病变 10年无再次手术的存活率 70 80 %,机械瓣膜 10年无再次手术的存活率 90 95 %,第一次MV修补手术到再次手术的时间间隔, 技术相关 = 6.04 7.18 瓣膜相关 = 45.44 33.65,手术相关的并发症: - 手术指征错误 严重的瓣膜疾病 瓣膜修补几率低 - 技术错误 修补技术不恰当 操作错误 - 第一次修补手术不完善 - 修补技术不稳定 瓣膜相关的并发症 : - 疾病的自然进展,Vietnam 心脏中心 Prof. NV Phan,风湿性瓣膜病手术修补的技术要领,风湿性返流 80 % 成功率 腱索增粗开窗术或切除术+Gore-Tex 瓣叶缩短心包补片 第二腱索松解术 瓣膜成形术风湿性瓣膜病中瓣环扩张非常常见 口角成形术,风湿性联合瓣膜病变 成功率存在差异 腱索增粗切除腱索/PM+ Gore-Tex 置换 腱索缩短心包补片 第二腱索松解术 瓣膜成形术心包补片技术能够使用更长的环 口角成形术+ 去除钙化,（1）瓣叶显著增厚或（2）双侧连合部钙化或（3）瓣环受限时应避免使用修补术,香港大学二尖瓣置换 vs 修补,Gore-Tex,心包补片,环 . 何种环 ?,一览表,房颤是一种严重的疾病,十年死亡率 Framingham 研究,房颤患者心梗的发生率,按年龄分组,手术 - Maze 手术,二尖瓣修补,谢谢,symptoms,ESC 2007: 严重慢性器质性二尖瓣返流的手术指征 Eur Heart J 2007 28:230-268,有症状的患者伴 LVEF 30% and ESD 45 mm and/or LVEF 55 mm) 对药物治疗反映不佳，且能够修补的可能性高，死亡率较低 无症状的患者伴左心室功能正常， IIbB 且能够修补的可能性高，手术风险低,Mitral Valve Repair Strategies Perspective EAST,Dr. Tim Wing-Kuk Au FRCS , FHKCS Consultant Surgeon Honorary Clinical Assistant Professor Department of Cardiothoracic Surgery The University of Hong Kong, Queen Mary Hospital, Hong Kong SAR,New Horizon in Cardiovascular Treatments December 2008 Shanghai, China,Cleveland Clinic,Quantitative Determinants of the Outcome of Asymptomatic Mitral Regurgitation,Maurice Enrique-Saran et al.
