Purpose of study(1) We aimed to reconstruct the motion of the heart surface during heart beat in 3 dimensions and clarify the movement of each coronary artery.(2) We aimed to establish a quantitative evaluation of various stabilization device and develop stabilization method of operative field new field.1) An image processing system :We developed the image processing system which acquired an image through two digital high speed cameras into a computer as 2 dimension of positional information. We reconstruct 3 dimensional image of positional information from these data provided by the system.2) Data acquisition in animal experiment :We used a pig under general anesthesia. After median sternotomy, the pericardium is opened.Metallic markers were attached on each coronary arteries of the heart surface. These makers were captured by two high speed digital video cameras as 2-dimentional coordinates and reconstructed to 3-dementional data points by a newly developed computer program.We analyzed the movement of left anterior descending coronary artery, left circumflex artery and right coronary artery.3) Results(1) We evaluated the control data of 3 dimensions of exercise of each coronary artery (left anterior descending coronary artery, left circumflex artery and right coronary artery) of the pig heart surface and acquired the parameters such as kinetic tracing, amplitude of movement, displacement distance per one beat, rate, acceleration were clear.(2) We compared various stabilizers, a change in 3 dimensional movement by pharmacological modification in animal experiment.We are now trying to evaluate the effect of Octpus4.3(Medtronic) and OPVAC Synergy II (ESTECH) for comparison of a mechanical stabilizer, and β-blocker (Landiolol Hydrochloride : Ono-1101) for pharmacological stabilization.

研究目的（1）我们的目的是在三个维度上重建心脏表面的运动运动，并澄清每个冠状动脉的运动。（2）我们旨在建立对各种稳定装置的定量评估，并开发了操作新领域的稳定方法。1）图像处理系统：我们开发了图像处理系统，这些系统通过两个数字速度启动了一个数字速度，将图像处理系统置于2个计算机上，将一个计算机置于2个计算机上。我们从系统提供的这些数据中重建了位置信息的3维图像。2）动物实验中的数据采集：我们在全身麻醉下使用了猪。中位胸骨切开术后，将心包打开。金属标记附着在心脏表面的每个冠状动脉上。这些制造商被两个高速数字摄像机捕获，作为二维坐标，并通过一个新开发的计算机程序重构为3个剂量数据点。我们分析了左前降冠状动脉的运动，左下冠状动物的运动，左弯曲冠型艺术和右冠状动物艺术和右冠状动物3）的结果（1）我们评估了练习的3级冠军艺术的对照数据（1）猪心脏表面的艺术和右冠状动脉艺术，并获得了参数，例如动态追踪，运动的放大器，每一次节拍的位移距离，速率，加速度清晰。机械稳定剂和β受体阻滞剂（盐酸兰多尔：ONO-11101）用于药理稳定。
