目的：从发生学角度探讨心肌血管重建术的供血机理。方法：本文采用不同胎龄的人胎心１３个，用墨汁灌注血管、组织切片染色法，观测左心室壁与心腔的血管交通状况。结果：显示人类胚胎早期的心脏，心室壁结构类似海绵状，心腔与心壁间存在着许多窦状通道。这类管道包括肉柱间隙、心肌窦样管等，其排列、配布及在心室壁的分布范围随着胎儿生长、结构重建而不断变化。其胚胎发育过程重复了种系发生的各个阶段。结论：提示激光心肌血管重建术从心腔直接供血，与人胚早期者相类似。
Objective: To investigate the blood supply mechanism of myocardial revascularization from the perspective of genesis. Methods: In this study, 13 fetal heart of different gestational age were used to inoculate blood vessels with ink and histological sections to observe the blood flow of the left ventricular wall and the heart cavity. Results: The early human embryonic heart showed a sponge-like structure of the ventricular wall. There were many sinus channels between the heart chamber and the heart wall. Such channels include the meat column space, cardiac sinus tube, etc., the arrangement, distribution and distribution in the ventricular wall with fetal growth, structural changes and constantly changing. Its embryonic development repeats all stages of phylogeny. Conclusion: It is suggested that laser myocardial revascularization directly supplies blood from the heart cavity, which is similar to the early stage of human embryo.
