引领起搏新篇章| 南京市第一医院成功完成 3T MRI兼容双腔心脏起搏器江苏地区首例植入

CBS2020

生命如此脆弱

危机与转机

竟在眨眼之间

而医者手握生死线

义无反顾

病例详情

患者为75岁,女性,心电图提示三度房室传导阻滞。南京市第一医院心内科胡作英主任带领的起搏小组通过病情讨论,制定了详细地治疗方案,认为患者病情符合心脏起搏器植入适应证,考虑到患者年龄偏大,未来需要进行MRI检查诊断的需求较高,传统起搏器不允许行核磁检查,在与患者和家属充分沟通后,决定选择国内首个3T&1.5T MRI全身无限制兼容经静脉起搏器Astra™和首个3T &1.5T MRI兼容主动电极5076进行植入。手术在局部麻醉下进行,通过腋静脉穿刺建立通路,将起搏导线放置到心腔内部,并在患者胸前制作囊袋植入起搏器,手术过程顺利,患者术后反应良好。

3T MRI技术

经静脉起搏器是治疗心动过缓的一线手段,自该技术问世以来,就为无数患者解除了病痛,使其重获新生。由于起搏器患者平均年龄在65~70岁左右,正是肿瘤、心脑血管疾病以及骨关节疾病的高发年龄,中国数据显示,33.8%的起搏器植入患者具有 MRI 扫描的真实需求。随着临床中对影像技术精准度要求的提高,3T MRI技术应运而生。与1.5T MRI相比,3T MRI具有扫描速度快,图像质量更清晰的特点,并能够提供更丰富的诊断信息,给患者带来更多临床益处。越来越多的医院也将3T MRI作为常规影像检查的首选,因此临床中对于3T MRI兼容起搏系统的需求也更为迫切。

Astra双腔起搏器简介

Astra起搏器为磁共振环境条件安全的植入式心脏起搏器,患者可接受临床1.5T和3T场强的磁共振成像全身检查。此外,Astra起搏器和抗核磁电极任意组合都可实现MRI扫描兼容。对于MRI兼容,无扫描部位和体位限制,无患者身高限制,无MRI扫描时长限制,实现全身无限制磁共振兼容。

Astra起搏器除了是国内首个实现 3T&1.5T MRI全身无限制扫描的经静脉起搏器,还具有超长的使用寿命,可减少更换次数,降低感染风险。其超长的使用寿命得益于全新的电路硬件结构和优化的系统电路设计,由于其改进的电池,能够支持更大耗电量需求,大幅降低系统能耗,从而极大提升了机器使用寿命,双腔起搏器预估寿命为15.3年。

11月12日,胡作英主任团队成功完成江苏省首例3T MRI兼容经静脉起搏器的植入!该植入的成功落地,标志着我院心内科双腔心脏起搏器植入治疗进入到3T MRI全身兼容新时代,引领着心血管疾病的诊治水平整体迈上了新的台阶!
