Review
Bicuspid aortic valve related aortopathy is known to significantly increase the risk for catastrophic aortic events and, therefore, represents a considerable health burden. Albeit of ongoing research in this field including genetic, molecular, hemodynamic and morphologic aspects, bicuspid aortic valve related aortopathy still represents an imperfectly understood disorder. This lack in knowledge results in a lack of consistency considering different therapeutic approaches. Recent studies have provided new insights into the etiology and clinical impacts of bicuspid aortic valve related aortopathy in different clinical settings, leading to a growing body of opinion towards a more individualized surgical approach than currently provided by the guidelines. Especially valvular hemodynamics-stenosis and regurgitation-seem to have significant impact on the development of bicuspid aortic valve related aortopathy. In this context, there is evidence that regurgitation of bicuspid aortic valves is the more fatal pathomechanism. Furthermore, "age" represents an aspect that should be taken into account when deciding whether to replace the aorta or not, because the diameter depends mainly on a patients age. The same diameter of the aorta in a 70-year old and a 20-year old patient has to be interpreted differently and should, therefore, result in different therapeutic strategies.

Review
Unicuspid aortic valve (UAV) is a rare congenital aortic valve anomaly. It has 2 subtypes and often is associated with aortic valve dysfunction and corresponding clinical presentations. Echocardiography is the first choice of diagnostic method for UAV. Three-dimensional echocardiography has played an increasingly important role in diagnosis, intraprocedural guidance, and post-procedural assessment in recent years. There remain challenges in distinguishing UAV from bicuspid aortic valve or tricuspid aortic valve. Misdiagnosis is most resulted from raphes or leaflet calcifications. Multi-modality imaging has obvious advantages over single-modality imaging and is crucial for UAV diagnosis. Accurate identification of aortic valve morphology is important to choose the best treatment. Aortic balloon valvoplasty, surgical valvotomy, commissurotomy, Ross procedure, surgical valve repair, and surgical replacement are most common treatment modalities of UAV. In this review, we aim to discuss UAV including epidemiology, definition, classification, diagnostic importance and necessity, valvular function, clinical presentation, associated disorders, noninvasive diagnostic modalities, and therapeutic approaches.

OBJECTIVE
During the last decade, special concerns have been raised about the anatomic relationships among the sinotubular junction, ventricular-aortic junction, and virtual basal ring to improve the results of root reconstruction. The aim of this study is to evaluate the in vivo anatomy of the aortic root after reimplantation with the Valsalva graft and the anatomic relationship between its components.
METHODS
We analyzed 10 consecutive patients with tricuspid aortic valves who underwent reimplantation with the Valsalva graft between September and December 2019. Surgical clips were applied as markers at the level of proximal annular knots and at the distal reimplanted commissures on the neo-sinotubular junction. Electrocardiogram-gated computed tomography scan of the aortic root was performed. Coordinates of the markers were exported on a 3-dimensional modeling software, and the distances between the virtual basal ring and the Dacron graft basal landmarks were measured.
RESULTS
The mean heights of Dacron graft basal landmarks from virtual basal ring were right-left commissure 7.1 ± 5.1 mm; right sinus 4.7 ± 4.1 mm; right-noncoronary commissure 2.8 ± 2.2 mm; noncoronary sinus 1.4 ± 1.6 mm; left-noncoronary commissure 2.2 ± 2.3 mm; and left sinus 2.0 ± 0.9 mm. The mean planar distances of basal Dacron graft landmarks from virtual basal ring (thickness) were right-left commissure 5.3 ± 3.1 mm; right sinus 2.8 ± 1.4 mm; right-noncoronary commissure 2.2 ± 1.5 mm; noncoronary sinus 1.5 ± 1.5 mm; left-noncoronary commissure 1.3 ± 1.0 mm; and left sinus 3.4 ± 2.5 mm.
CONCLUSIONS
After reimplantation, despite a complete dissection of the root, slight asymmetry of graft proximal seating exists. The inner annuloplasty is on the virtual basal ring, and the proximal edge of the Dacron graft is on the ventricular-aortic junction at a slightly different thickness and height along the annular circumference. At the level of the right sinus and left/right commissure, the Dacron graft is higher than the virtual basal ring and the relative wall thickness is increased. The annular stabilization is unaffected.
