Valve-Sparing Root Replacement: Aortic Root Remodeling with External Subvalvular Ring Annuloplasty
نویسندگان
چکیده
The original valve-sparing procedures for aortic root aneurysms were remodeling and reimplantation of the aortic root. The remodeling technique provides more physiologic movement of the cusps within 3 reconstructed neo-sinuses, thus preserving root expansibility through the interleaflet triangles. However, the durability of remodeling has been a matter of concern due to the high rate of aortic insufficiency when annular dilation is not addressed. Therefore, a modified approach was developed, combining a physiologic remodeling of the root with a subvalvular annuloplasty. This case report highlights the first case of successful aortic root remodeling with external subvalvular ring annuloplasty in Korea.

Valve sparing root replacement: the remodeling technique with external ring annuloplasty.
A standardized approach to aortic valve repair is described associating a physiological remodeling of the root, with resuspension of cusp effective height and a subvalvular aortic annuloplasty using an external expansible ring. This device achieves a complete calibrated annuloplasty, in order to increase cups coaptation height and protect the repair. This is a video-atlas describing the surgica...

OBJECTIVE Dilation of aortic annulus, sinuses of Valsalva, and sinotubular junction (STJ) diameters are the characteristic lesions of aortic root aneurysm. The remodeling technique reduces STJ diameter and creates three neosinuses of Valsalva. Alternatively, the reimplantation technique reduces both annulus and STJ diameters to the detriment of aortic root dynamics. Although the remodeling tech...
متن کاملEarly results of a novel technique for ring-reinforced aortic valve and root restoration.
OBJECTIVES Surgery for aortic root aneurysm without valve stenosis is increasingly being transformed from the Bentall procedure to valve-sparing aortic root remodelling or reimplantation. In this report, a new repair option is explored, with full functional 'restoration' of the aortic root complex using a geometric annuloplasty ring, leaflet repair, and sinus/ascending aortic replacement with a...
متن کاملValve-sparing aortic root replacement in patients with Marfan syndrome-the Homburg experience.
Aortic root dilatation occurs in most patients with Marfan syndrome with secondary valve failure or aortic complications being frequent consequences (1). The traditional surgical approach has been composite replacement of aortic valve and root, first described in the 1960s (2). Since the advent of valve-preserving aortic surgery, different techniques (3,4) have also been applied to Marfan patie...

OBJECTIVE Evaluate the results of various surgical procedures used for aortic root replacement in children with aortic root aneurysm. METHODS Between 1986 and 2007, 23 children (less than 16 years of age, mean age: 8.1+/-5.1 years) underwent elective aortic root replacement for aortic root aneurysm (with associated aortic insufficiency in 10 patients). All had connective tissue defect syndrom...
