Effectiveness of Prosthetic Ring Annuloplasty for Aortic Valve Repair

Aortic valve repair (AVR) techniques have been growing fast in the last 2 decades. The geometric relationship and dynamic behavior of aortic root components have been seen to ensure valve competence when leaflets have no structural lesions. Aortic leaflets lesions and/or dilatation of the ascending aorta and root lead to aortic regurgitation that need surgical repair. Repair procedures usually aimed to treat the leaflets dysfunction and restore the annulus. The aortic annulus is the tightest part of the functional aortic annulus complex and is defined as a virtual ring at the level of the hinge points of the aortic valve leaflets.
