Abstract

Multi-detector computed tomography is commonly used as a preoperative screening tool for coronary artery bypass grafting. Electrocardiographically gated cardiac computed tomography facilitates accurate identification and assessment of the target coronary artery segment. While cardiac computed tomography can visualize the morphology of coronary arteries, the surgeon’s view of the heart surface may differ considerably because the arteries can be obscured by the myocardium (myocardial bridge), pericardial fat, or parallel-running coronary branches. To address this, we developed a dedicated computed tomography imaging method that incorporates tissue classification based on cardiac anatomy. We present this imaging method in the case of a 77-year-old female patient diagnosed with angina pectoris who underwent coronary artery bypass grafting. This method may help cardiac surgeons navigate cardiac anatomy more accurately, enhance confidence during surgical exploration of the target vessel, and improve communication with imaging professionals.

多探测器计算机断层扫描心脏表面的高分辨率可视化：冠状动脉旁路移植术的案例研究

多探测器计算机断层扫描通常被用作冠状动脉旁路移植术的术前筛查工具。心电图门控心脏计算机断层扫描有助于准确识别和评估目标冠状动脉段。虽然心脏计算机断层扫描可以看到冠状动脉的形态，但外科医生对心脏表面的观察可能会有很大的不同，因为动脉可能被心肌（心肌桥）、心包脂肪或平行运行的冠状动脉分支所掩盖。为了解决这个问题，我们开发了一种专用的计算机断层成像方法，该方法结合了基于心脏解剖的组织分类。我们提出这种成像方法的情况下，77岁的女性患者诊断为心绞痛谁接受冠状动脉旁路移植术。这种方法可以帮助心脏外科医生更准确地导航心脏解剖结构，增强手术探查靶血管时的信心，并改善与成像专业人员的沟通。
