Abstract
An aortic valved tube which is used in human implants to replace the corresponding cardiac valve and ascending section of the aorta itself, incorporates a cardiac valvular prosthesis in its proximal end. The valved tube has two integral branches which project from opposite points with an inclination relative to the longitudinal axis of the tube, which branches are for effecting the anastomosis of the ostiums, corresponding to the left and right coronary arteries, respectively. The branches, as well as the sectors above and below the branches, are reinforced by a thicker wall in those areas while, maintaining the inside diameter of the tube itself.
