A special surgical technique is required for minimal-invasive cardiac surgery. The view for the coronary artery anastomosis under beating heart conditions is important and coronary artery blood might prevent a clear view of the opened coronary artery vessel. A new system called VisoFlo promises to improve visualisation at the surgical site. VisoFlo delivers a column of air to help provide a clear view of anastomosis site and in addition has a controllable mist to help prevent desiccation of the graft and surrounding tissue. This system was tested on 45 patients with coronary-artery-bypass graft surgery under beating heart conditions and at 65 patients with standard coronary-artery-bypass graft surgery. Our conclusions are, that the VisoFlo system is easy to use, guarantees a clear view of the anastomosis site and the surgical work will not be impaired.
微创心脏手术需要一种特殊的外科技术。在心脏跳动的情况下进行冠状动脉吻合时的视野很重要，冠状动脉血流可能会妨碍对开放的冠状动脉血管的清晰视野。一种名为VisoFlo的新系统有望改善手术部位的可视化效果。VisoFlo可输送一股气流以帮助提供吻合部位的清晰视野，此外还有可控的喷雾以帮助防止移植物和周围组织干燥。该系统在45例心脏跳动情况下进行冠状动脉搭桥手术的患者以及65例标准冠状动脉搭桥手术的患者身上进行了测试。我们的结论是，VisoFlo系统易于使用，能保证吻合部位的清晰视野，且不会妨碍手术操作。
