“…While extreme values can lead to tearing, large values may induce tissue calcification over time (Shoen and Levy, 2005). Better understanding of the interplay between valve dimensions and function would also help perfect aortic valve repair procedures (Kollar et al, 2009;Labrosse et al, 2006).…”

“…The non-coronary sinus has only fibrous tissue 1,9,13 . The right coronary sinus is the largest and the left one the smallest 6,14 . The three sinuses are functionally comparable 13 and have a stress-sharing mechanism for the leaflets, which contributes to the durability of the native aortic valve 14,15 .…”

Introduction The complexity of the aortic valve and aortic root is appreciated, especially by specialists in medical imaging and by surgeons who devise and perform aortic valve repair. However, the terminology used to describe the components of the valve differs between different specialists and even within one group of specialists. The aim of this review was to discuss the aortic valve and its root. Discussion The following structures need proper labelling before the root itself can be described unequivocally: valve leaflets, commissures, sinuses of Valsalva, interleaflet triangles, sinutubular junction and ventriculo-aortic junction. Especially the latter deserves attention since there is an anatomic as well as a haemodynamic junction. The difference between both junctions is the key to understand the aortic valve. Its understanding is also of vital importance for surgeons in performing durable aortic valve reparations. Conclusion The differences in terminology of the components of the aortic valve are probably long lasting. Therefore, a clarifying definition of every component described in any scientific manuscript should be provided.

“…We are still awaiting the definite guidelines on the appropriate method of restitution in individual situations. Some recent studies have attempted a detailed analysis of the three-dimensional situation to provide more robust means of selecting the appropriate technique and necessary individual amendments [15,77]. The anatomical complexity of the aortic root remains a challenge even for senior surgeons.…”

“…Owing to the complex nature of the disease but also driven by surgeons seeking new challenges, a variety of technical alterations have found their way into the literature. Additional annulus support for the Yacoub technique, facilitated implantation in the David technique, and modalities to estimate the proper prosthesis diameter and the spatial alignment of the commissures within the prosthetic graft have all been described [14][15][16][17]. An overly positive interpretation of apparently promising early data provided an incentive to perform reconstructive surgery.…”

After almost 20 years aortic root reconstruction modalities have evolved into reasonable and useful surgical measures. Short and long term results match those of aortic composite replacement. Three major restitution strategies have found widespread acceptance: Root replacement with valve reimplantation (David-Procedure), root remodeling (Yacoub-procedure), or commissural resuspension. In the wake of these modalities also isolated aortic valve repair techniques have found renewed interest in order to broaden the indication for reconstructive surgery. Some euphemistic and hence biased interpretation, however, should be considered when looking at the clinical results. Reimplantation and remodeling procedures as well as several valve repair maneuvers are technically demanding unfolding their potential only in the hands of an experienced surgeon. Definite guidelines regarding the appropriate method of restitution required to serve best in the patient's individual situation are not yet at hand although they are about to emerge.
