[Early ischemic lesion of the myocardium in a case of unusual developmental anomaly of the coronary vessels and coronary thrombosis].

An uncommon form of anomaly of coronary arteries is reported, similar to which had not as yet been published. A single right arteria coronaria was found having an only left branch with a thin vena-like wall, descending on the anterior surface of the heart. The lumen of the sclerotic right arteria was occluded by a thrombus at the point of origin of ramus descendens posterior. The cause of death was an acute cardiac failure, in which authors prescribe an important part to the anomaly of coronary arteries. Areas of myocard getting blood supply from the occluded arteria were investigated by the method of fuchsinorrhagia. Authors believe, that this reaction is suitable for the demonstration of the acute, early ishaemic lesions of the myocard.
