Abstract: As the myocardial capillaries drain tassel-like into the peripheral end of sinusoids, the venous system of the myocardium begins in the sinusoids and plays an important role in the regulation of myocardial circulation. The sinusoids dilate in response to inadequacy of the arterial vascularization and their expansion has been found to be inversely proportional to the blood flow in the coronary arteries. The sinusoids become more dilated and prominent with coronary dilators and reinforcement of myocardial vascularization by cardiopexy techniques, causes the sinusoids to become dilated.
