Corrective aortic dislocation

The curve of the normal primitive heart tube protrudes to the right, hence the name D-Loop, so that the right ventricle is located right forward and the left ventricle is located left rear. If the central tube is curved not to the right but to the left during development, which is called the left loop (L-Loop), the anatomical right ventricle is located at the left rear and becomes the ventricle of the arterial system. Ventricular system of the ventricle. At this time, the arterial trunk is still separated and rotated, but the position is reversed. In this way, the main pulmonary artery is located in the right rear and the ascending aorta is located in the front left. Although the position of the large blood vessels is reversed, the pulmonary artery is still connected to the venous ventricle, and the aorta is connected to the arterial ventricle. Aortic dislocation. The left and right branches of the atrioventricular conduction beam are still distributed to the corresponding anatomical ventricle, but the position of the peripheral ventricle is opposite, so the conduction beam is also opposite.
