JACC:经导管瓣膜修复治疗二尖瓣返流

2019-07-22 xiangting MedSci原创

PASCAL修复系统在治疗3+或4+级MR方面具有可行性和可接受的安全性。无论病因如何,MR严重程度明显降低,并伴有功能状态、运动能力和生活质量的显著改善。

这项研究报告了多中心、前瞻性、单组CLASP研究纳入的二尖瓣返流(MR)患者使用PASCAL经导管瓣膜修复系统(爱德华兹生命科技,欧文,加利福尼亚州)的手术和30天结局。

严重MR会引起症状,影响生活质量,不治疗时会导致运动能力下降。

入组条件为尽管采用了最佳药物治疗,仍有3级或4级MR,并被当地心脏团队认为适合该研究的患者。所有结局均在术后30天进行评估。主要不良事件(MAEs)由独立的临床事件委员会裁定,超声心动图图像由一个核心实验室评估。主要安全性终点是30天时MAEs发生率。

2017年6月至2018年9月,共纳入62例3+或4+级MR患者。平均年龄为76.5岁,51.6%的患者纽约心脏病协会功能分级III级或IV级,56%为功能性,36%退行性和8%为混合病因。30天时,MAE发生率为6.5%,全因死亡率为1.6%,无卒中;98%的患者MR≤2+级,86%的MR≤1+级(p<0.0001);85%纽约心脏病协会功能分级I或II级(p<0.0001)。六分钟步行距离改善了36米(p=0.0018),堪萨斯城心肌病问卷和EQ-5D分数分别提高了17(p<0.0001)和10(p=0.0004)分。

PASCAL修复系统在治疗3+或4+级MR方面具有可行性和可接受的安全性。无论病因如何,MR严重程度明显降低,并伴有功能状态、运动能力和生活质量的显著改善。
