Surgical management of three diseases of the aortic root has improved considerably in the last 10 years. Results and prognosis are excellent following complete open heart repair of a fistula of a sinus of Valsalva. In supravalvular aortic stenosis surgical mortality is negligible when obstruction is localized.

The anatomy of the aortic root
Clinical Anatomy, 2013The aortic root is the anatomical bridge between the left ventricle and the ascending aorta. It is made up of the aortic valve leaflets, which are supported by the aortic sinuses (of Valsalva), and the interleaflet triangles interposed between the basal attachments of the leaflets.

Anatomy of the aortic root: implications for aortic root reconstruction
General Thoracic and Cardiovascular Surgery, 2017Since the introduction of valve-preserving root replacement and aortic annuloplasty, precise understanding of the aortic root anatomy has emerged as a key to successful aortic valve-preservation surgery. Fundamentally, surgeons need to know the precise anatomical definition and structure of the aortic root, including its normal dimensions, know the ...

The shape of the aortic valve leaflet was first described by Philiston [1] in the 4th century BC as semilunar, and in 1513 Leonardo da Vinci [3] depicted in a drawing the geometry of the orifice of an opened and closed aortic valve as triangular and with three adjacent hemispherical forms, respectively (Figs. 1–3). Valsalva described the aortic sinuses

Impact of aortic root annuloplasty on 3D aortic root geometry
Journal of Surgical Research, 2018The aim was to evaluate the impact of aortic root (AoR) annuloplasty on 3D AoR deformation.In experimental setup, Yacoub procedure and Yacoub with annuloplasty were performed. Results were compared to native AoR. In each AoR modality, six microsonometric (2 mm, 200 Hz) crystals were implanted at the sinotubular junction (STJ) and at the AoR base (AoB).

New Aortic Root Remodeling Surgery in Aortic Root Aneurysm
The Annals of Thoracic Surgery, 2010We have introduced a new surgical technique for aortic root remodeling in aortic root aneurysm, comprised of aortic annuloplasty, reduction of sinus of Valsalva, and wrapping of the aortic root.At the level of the basal ring, the aortic annulus is fixed with the collar of a Gelweave Valsalva vascular graft (Vascutek, Ltd, Inchinnan, UK).

Dynamic Normal Aortic Root Diameters: Implications for Aortic Root Reconstruction [PDF]
The Annals of Thoracic Surgery, 2011 The main aim of this study is to determine the normal diameter and the relationship of aortic root components in healthy adults, and to provide a morphologic foundation for future clinical applications.Echocardiography was performed in 314 normal subjects who were divided into five groups according to age.

Echocardiography of the aortic root
The American Journal of Medicine, 1977The anterior and posterior walls of the aortic root are recognized as a pair of parallel linear signals which move anteriorly in systole and posteriorly in diastole. Valve cusps appear as thin lines which move briskly toward the periphery of the aortic lumen in systole and coapt in the middle in diastole producing a box-like configuration.

Aortic Root Wrapped Procedure for Treating Aortic Root Sinus Aneurysm
Surgical Innovation, 2014Background. To develop a relatively simple and effective and low-risk operation, aortic root wrapped procedure, to treat aortic root aneurysm or ectasia. Methods. From June 2008 to September 2010, 15 patients were accepted for aortic root wrapped angioplasty procedure, Marfan’s syndrome with aortic root ectasia in 2 cases, and aortic sinus aneurysm ...
