保留冠状动脉的猪心螺旋形心室肌带的解剖

Objective Based on the Helical Ventricular Myocardial Band (HVMB) theory proposed by Torrent-Guasp,the ventricular myocardial hand extends from the root of the pulmonary artery to the root of the aorta with two helical coils.This new theory is considered as a revolutionary concept for further understanding the global, three-dimensional and functional architecture of the ven- tricular myocardium. No repot had described techniques for disecting HVMB while keepin～ the integrity of the coronmy artery sys- tern. We explored techniques for dissecting HVMB in swine.Methads 33 fresh swine hearts were randomly divided intoll groups, 3 bearts in each. 160% barium sulfate (type I)suspmmion was injected into the coronary artery system. The coronary arteries were li- gated. The strial tissue was removed following puuing the hearts in boiling water then cooling for several hours. The superficial coro- nary vessels and fat tissue around the atrio-ventricular taxi inter-ventricular sulcus we～'e preserved. Some branches of the left anterior descending artery, distal segment, of posterior descending branch, and middle and distal segment of obtuse marginal branches were mu- tilated appropriately. HVMB dissection was completed with fingers in accordnce with Torrent Guasp' s technique. Results A contin- ued bundle of muscle, originated at the root of pulmonary artery and ended at the root of aorta, was unwrapped along the major dire- tion of the cardiac muscle fiber in all of the 33 hearts with spating of the coronary artery. The swine hearts' ventricular myocandium was cumosed of two loops, with basal loop firm the root of the pulmonart artery to the anterior papillary muscle and apical from the beginning of the anterior papillary muscle to the root tithe aorta. Each loop consisted of two segments: the right segment-coincid- ing with the right ventricular free wall and the left segment-coinciding with the basal d the left ventricular free wall. Posterior papillary muscle, which belongs to the descendant segment, denmrcated the border between the descendent and the ascendant of the HVMB's apical loop. Conclusion Although controversies about the theory of the HVMB remain, we have dissected the HVMB in the swine hearts' ventricular myocardium successfully with sparing of the coronary artery systems. This dissection procedure provides technical information for the studies of associated diseases based on the theory of HVMB.

保留冠状动脉的猪心螺旋形心室肌带的解剖

目的 探索保留完整冠状动脉的猪心螺旋形心室肌带(helical wentricular myocardial band,HVMB)的解剖方法.方法 取33只新鲜猪心,随机分成11组,每组3只,冠状动脉内分别选择性地注入160%硫酸钡(Ⅰ型)混悬液,猪心于水中煮沸、冷却后移除心房组织,但完整保留心脏表面的冠状动脉及房室沟和室间沟周围的脂肪组织,适当离断冠状动脉的主干及其分支,参考Torrera-Guasp等的HVMB解剖方法用手指行钝性解剖.结果 在冠状动脉保留完整的基础上,将猪心心室肌解剖出一条起点为肺动脉根部,终点到主动脉根部连续的肌肉带.结论 成功保留完整冠状动脉的猪心HVMB解剖有益于完善和加深HVMB理论的理解和认识,可为探求基于HVMB理论的冠状动脉疾病及其相关疾病的研究提供解剖上的技术支持.
