我们的实验室正在开发一种灌注固定各种解剖研究心脏标本库。到今天为止，我们有超过240个标本。用于制备这些样品的具体方法我们先前已经描述3。本研究中描述了一种新颖的方法，用于绘制人类心脏的静脉系统和为解剖的数据库，该数据库可用于心脏血管内装置的设计的发展。 以前的研究已经对现场患者使用磁共振（MR）和CT 5-12成像来评估心脏静脉系统...

anatomical reconstructions of the human cardiac venous system using contrast-computed tomography of perfusion-fixed specimens

在人的心脏的静脉系统的复杂性和相对变化的详细的了解心脏的装置，需要访问这些船只的发展是至关重要的。例如，心脏的静脉解剖是已知的主要限制之一为正确传送的心脏再同步疗法（CRT）的1因此，开发人类心脏的静脉系统的解剖参数的数据库可以帮助设计的CRT（阴极射线管）交付设备来克服这种限制。在这个研究项目中，解剖参数，获得从使用造影计算机断层扫描（CT）成像和建模软件（Materialise公司，比利时鲁汶）静脉系统的三维重建。下面的参数进行评估的每个脉：电弧长度，扭曲度，分支角度，冠状静脉窦口的距离，和血管直径。 CRT是一个潜在的治疗巴蒂淋洗液机电不同步。约10-20％的心脏衰竭患者可能受益于CRT 2。机电不同步意味着部分较早或较晚的心脏比正常传导通路的的心肌激活和合同。在CRT，心肌的dyssynchronous区域与电刺激治疗。 CRT起搏通常涉及起搏右心房（RA），右心室（RV）和左心室（LV）的线索，刺激产生更多的重新同步的节奏。 LV电极通常是植入心脏的静脉内，其目的叠加在工地内最新的心肌激活。 我们相信，模型和分析，将促进解剖教育患者，学生，医生和医疗设备设计者。这里采用的方法也可以用来研究我们的人体心脏标本的解剖特点，如冠状动脉。为了进一步鼓励本研究的教育价值，我们已经共享了我们的免费访问网站的静脉模型： <a href="http://www.vhlab.umn.edu/atlas" target="_blank">www.vhlab.umn.edu /地图集</a> 。

表2列出了42人的心脏标本为主要心脏静脉解剖参数中位数。所有心脏标本包含一个后室间静脉（PIV）和前室间静脉（AIV）。有些标本包含一个以上的后静脉的LV（PVLV），后外侧静脉（PLV），左外静脉（LLV），和/或前外侧静脉（ALV），而其他的心可能不会有一个或这些特定的两个静脉呈现。 <table border="1"><tbody><tr><td> 使用的材料 </td></tr><tr><td>人类的心灵灌注固定</td></tr...
