Abstract

Disclosed herein a valved aortic root prosthesis comprising a vascular prosthesis with a cuff fastened to the proximal end thereof and a valve mounted in the cuff, wherein the cuff is provided with three marks at an angle of 120 degrees from each other, which divide the cuff into three zones corresponding to the right coronary sinus, the left coronary sinus and the non-coronary sinus, while the vascular prosthesis is provided with two apertures situated above the zones corresponding to the right and left coronary sinuses, wherein the aperture in the left coronary sinus zone is provided at a level of 5-25 mm from the cuff, and the aperture in the right coronary sinus zone is provided at a level of 25-55 mm from the cuff, and each aperture has a vascular prosthesis sewn thereto for connection to the adjacent coronary artery.

Claims

1. Valved aortic root prosthesis comprising:

a vascular prosthesis with a cuff fastened to the proximal end thereof and a valve mounted in the cuff,

wherein the cuff is provided with three marks at an angle of 120 degrees from each other, which divide the cuff into three zones corresponding to the right coronary sinus, the left coronary sinus and the non-coronary sinus, while the vascular prosthesis is provided with two apertures situated above the zones corresponding to the right and left coronary sinuses, wherein the aperture in the left coronary sinus zone is provided at a level of 5-25 mm from the cuff, and the aperture in the right coronary sinus zone is provided at a level of 25-55 mm from the cuff, and each aperture has a vascular prosthesis sewn thereto for connection to the adjacent coronary artery.
