A human heart with an unusual superior vena cava was dissected. This dissection suggested that the sinus coronarius and its branches (main veins of the heart) were left-sided vessels, and that the anterior cardiac veins were right-sided vessels. It was also suggested that the sinoatrial node near the right superior vena cava was the right-sided center of the conductive system, and that the atrioventricular node close to the sinus coronarius or left superior vena cava and descending into the ventricle was the left-sided center of this system. The left coronary artery was thicker than the right one, and issued circumflex and anterior interventricular arteries. These findings indicate that the human heart mainly consists of left-sided elements.
