Left ventricular assist devices provide hemodynamic support to improve quality of life and long-term survival in patients with end-stage heart failure. The HeartMate 3 (Abbott, Abbott Park, IL) left ventricular assist device uses magnetically levitated impeller technology, improving durability and reducing pump thrombosis. Sternum-sparing implantation may reduce perioperative bleeding and infection, improve mobility, decrease hospitalization duration, and reduce right ventricular dysfunction. We describe the first Canadian HeartMate 3 implantation via bilateral minithoracotomy. Our case supports the compatibility of the HeartMate 3 device with sternum-sparing approaches and highlights the feasibility of intrapericardial tunnelling of the outflow graft.
左心室辅助装置为终末期心力衰竭患者提供血流动力学支持，以改善生活质量和长期生存率。HeartMate 3（雅培公司，伊利诺伊州雅培公园）左心室辅助装置采用磁悬浮叶轮技术，提高了耐用性并减少了泵内血栓形成。保留胸骨植入术可减少围手术期出血和感染，改善活动能力，缩短住院时间，并减少右心室功能障碍。我们描述了首例通过双侧小切口开胸进行的加拿大HeartMate 3植入手术。我们的病例支持HeartMate 3装置与保留胸骨方法的兼容性，并突出了流出道移植物心包内隧道化的可行性。
