我国心脏瓣膜植入手术进入“分钟级”

过去心脏病患者进行瓣膜植入需要打开胸腔、花费数小时手术时间,而记者30日了解到,由我国最新研发的J-Valve心脏瓣膜置换系统,不仅用微创方式替代传统的开胸手术和体外循环,还将瓣膜植入时间缩减到3-7分钟,在减少患者痛苦的同时大大降低手术风险。

J-Valve系统发明人、苏州杰成医疗科技有限公司董事长张极向记者介绍,传统的心脏瓣膜置换方式需要进行开胸手术。医生在患者胸部开出数十厘米长的切口,运用体外循环、在病人心脏停跳的情况下手工更换瓣膜,手术时间一般长达3到4小时,对于年龄较大、身体虚弱的病人,手术风险很高。而最新的J-Valve心脏瓣膜植入系统,用微创置换技术取代开胸,病人手术无需心脏停跳和血液体外循环,只要在胸口开出几厘米的小伤口,J-Valve瓣膜系统就能利用自带的活动定位装置完成瓣膜置换。

今年2月中旬,温哥华圣保罗医院选择用J-Valve技术为一例重度主动脉关闭不全患者实施了微创心脏瓣膜植入手术。手术完成后,该例病患6小时即起坐进食,3天出院。截至目前的医院随访显示,患者身体恢复状况良好。

在加拿大患者手术前,J-Valve心脏瓣膜置换系统已在中国医学科学院阜外心血管病医院、四川大学华西医院、上海复旦大学附属中山医院进行了100余例临床试验,临床效果显著。

阜外心血管病医院外科系统管理委员会主任王巍告诉记者,阜外医院、中山医院和华西医院自2014年3月到2015年7月一共运用J-Valve瓣膜治疗100多个病人。从效果上看,J-Valve与世界同类产品相比定位容易、治疗范围更广。

“微创瓣膜技术之前大多数应用于国外。J-Valve的临床试验成功,标志着中国在这个领域已迎头赶上。”复旦大学附属中山医院心脏外科主任王春生说。

据了解,全球现有心脏瓣膜病人1200万,每年都有几十万人因此离世。中国也是心脏瓣膜疾病高发国家,病人数量200万人以上,每年需要手术病人达20万人以上。

JAMA Cardiology:NBA球员的心脏有啥不一样?

从字面的定义来看,职业篮球运动员指的是一群比我们更高、更壮、也更加体能充沛的人。实际上,他们的心脏和我们相比,也有着不为人知的区别。与其他运动员相比,美国的篮球运动员突发心脏病造成的死亡率远高于其他类型的疾病。但是,众所周知,随着长期的体育运动锻炼,心脏会发生一定的变化,变得更大、更重、也会更厚。因此对于这群更加高大的运动员群体,其心脏已经与常人相比出现了一定的改变,我们对其突发心脏病风险的认识还

运动过度或不利于身体健康?

众所周知,有规律的锻炼是健康生活的重要组成部分,但论强身健体,运动过度或不利于身体健康呢? 根据最新的研究显示。 发表在《加拿大心脏病学杂志》上的文章表明,有越来越多的证据,高水平的剧烈运动可能有“毒”。该研究表明,锻炼太难和太久可能导致心脏永久的结构性变化,从而可能导致心律不齐。 然而,专家强调,这项研究是指高强度耐力运动,而不是你的典型的健身锻炼。 “我们真正谈论的是参加马拉松,铁人三

研究揭示心脏侧枝动脉形成机制

中科院上海生科院营养科学研究所周斌研究组利用遗传谱系示踪技术,揭示了心脏在损伤修复过程中侧枝动脉主要通过动脉生成的方式形成,为心肌梗塞等心血管疾病的研究提供了理论基础和新的思路。相关成果日前在线发表于《心血管研究》。 周斌研究组发现,Apln特异性地表达在冠状血管内皮细胞中,且主要表达在冠状毛细血管内皮细胞中,而基本不表达在大的冠状动脉血管内皮细胞中。利用Apln-CreER小鼠与报告基

最近,来自克利夫兰诊所的研究人员通过研究首次发现,靶向作用肠道微生物可以帮助抑制由富含红肉、鸡蛋及高脂肪乳制品而引发的心脏疾病;这项研究发现基于研究人员此前的研究结果,之前他们发现,氧化三甲胺(TMAO)—一种在动物脂肪消化过程中在肠道中产生的副产物,和动脉粥样硬化及心脏疾病的发生直接相关。 如今研究者在冷榨的特级初榨橄榄油和葡萄籽油中发现了一种名为DMB(3,3-二甲基-1-丁醇)的天然抑

Prev Med:拒绝久坐不动,否则胖子的心脏病风险会增加

久坐对有心脏疾病的患者不好,专家也建议心脏病患者应该坐坐动动,一直不运动只会加重其心脏病情。近期一项关于肥胖人群的研究发现,久坐会增加他们心脏病风险,反过来肥胖人群减少坐的时间就可以减少心脏病风险。研究者发现就算是爱运动的胖子,如果看电视玩电脑时间过长,心脏病风险依旧很高。久坐不动还与糖尿病和更差心血管健康息息相关。严重肥胖的患者很难做到指南推荐的每天30分钟的中到高强度的运动,虽然这有益于他们的
