摘要目的:分析使用J-Valve?系统行经心尖主动脉瓣置换术(transapical aortic valve implantation，TA-TAVI)治疗高危主动脉瓣关闭不全患者的中期临床预后。方法:回顾性收集2016年9月至2020年6月在浙江大学医学院附属第二医院连续收治的25例使用J-Valve?系统经心尖TAVI治疗的主动脉瓣关闭不全患者资料，分析总结术后全因病死率，不良事件发生率及心功能改善情况。结果:25例中男19例，年龄范围为59~83岁，平均年龄(72.3±27.11)岁。经胸超声心动图检查评估重度主动脉瓣反流比例达88%，心功能(NYHA分级)Ⅲ-Ⅳ级占92%。患者最常合并的基础病为高血压(占68%)，合并冠心病5例，既往心脏手术史3例，术前胸外科医师协会(the Society of Thoracic Surgeons，STS)评分为1.511%~27.674%，中位STS评分为4.27(2.914~6.033)%。手术均成功置入J-Valve瓣膜，无中转开胸。术后置入永久起搏器2例，CRRT 1例，中度及以上瓣周漏1例。手术早期疗效可观，不良事件发生率低，中期随访心功能及心室逆重构也有持续改善表现。结论:对于高危主动脉瓣关闭不全患者使用J-Valve?系统行经心尖TAVI可获得较好的围手术期安全性及中期预后。

abstractsObjective:To analysis the mid-stage prognosis of transapical aortic valve implantation(TA-TAVI) using J-Valve? system for the treatment of high-risk aortic regurgitation(AR) patients.Methods:Data of 25 patients with aortic regurgitation who had underwent transapical aortic valve implantation using J-Valve? system were collected in the Second Affiliated Hospital of Medical College of ZheJiang University from September 2016 to June 2020 . Analysis and summarize their postoperative all-cause mortality, the incidence of adverse events and the improvement in cardiac function.Results:There were 25 patients, including 19 males, the age rage from 59-83 years, the average age was(72.3±27.11) years. The levels of aortic regurgitation was evaluated by transthoracic echocardiography preoperatively, showed that severe AR accounted for 88%. The New York Heart Association(NYHA) of grade 3 or above was 92%. The most common comorbidity was hypertension, accounted for 68%. Coronary heart disease and history of cardiac surgery was 5 and 3 relatively in this study. The Society of Thoracic Surgeons score before surgery was 1.511%-27.674%, the average of STS score was 4.27(2.914-6.033)%. Successful J-Valve implantation was obtained in all 25 cases, no conversion to thoracotomy. After surgery, 2 patients required permanent pacemaker implantation, 1 patient needed continuous renal replacement therapy(CRRT) due to acute kidney injury, 1 occurred moderate or above paravalvular leak. The results showed good therapeutic effects in early-stage, low incidences of adverse events. The continued improvement of cardiac function and ventricular reverse remodeling could be observed in mid-stage.Conclusion:In this study, we can summarize that high-risk patients with aortic regurgitation treated with transapical aortic valve implantation using J-Valve? system can acquire great perioperative safety and mid-stage prognosis.
