Repair of dilated aortic root and sinotubular junction using a stabilizer ring.

Abstract

Aortic root aneurysm and dissection are potentially life-threatening conditions that involve a structural weakness of the aortic wall. Management of aortic root aneurysm (with or without aortic insufficiency) has recently been the subject of much scholarly discussion which resulted in some modifications. The current trend is a valve-sparing root repair or replacement as well as preserving or restoring the diameter of the aortic annulus and sinutubular junction. This manuscript reviews the etiology and diagnosis of aortic root aneurysm or dilated aortic annulus as well as a novel treatment approach. A newly patented apparatus that restores and repairs the aortic annulus and sinotubular junction is reviewed.
