Key result
A novel high-precision 3D reconstruction technique was successfully applied to evaluate the anatomical and functional features of the reimplanted aortic valve 18 months after the David I procedure.
Why the study?
Comprehensive data were lacking on the influence of initial geometric parameters of aortic root structures on the functioning of the reimplanted aortic valve after valve-preserving aortic root replacement.
Case Report (n=1)
High-precision 3D reconstruction of the aortic root provides detailed geometric assessment of the aortic valve before and after valve-sparing surgery, aiding in surgical planning and postoperative evaluation.
May aid detailed post-David I valve assessment in select cases; hypothesis-generating, requiring prospective validation before wider use.
Aneurysm of the aortic root accompanied by aortic insufficiency is a common cardiovascular pathology. The optimal method of surgical treatment of this pathology is the reimplantation of the aortic valve into the aortic root synthetic prosthesis (David procedure). Currently, there is no comprehensive data on the influence of initial geometric parameters of the aortic root structures on the functioning of the reimplanted aortic valve after valve-preserving aortic root replacement. We have introduced a novel technique for creation and segmentation of a three-dimensional reconstruction of the aortic valve and root, which involves the sequential application of two computer-aided design environments: In Vesalius v 3.1.1 (Centro de Tecnologia da Informação Renato Archer (CTI)) and 3- Matic v. 13.0 (Materialise, Leuven, Belgium). The proposed method allows accurate measurement and evaluation of spatial parameters of the AV leaflets, fibrous ring, sinuses of Valsalva and sinotubular junction. The developed technique was used to evaluate the anatomical and functional features of the aortic valve in a 68-year-old patient who underwent David I procedure. Segmentation and measurement of the geometric parameters of the aortic root were performed before operation, as well as 18 months after surgical treatment. To assess the function of the reimplanted aortic valve during the long-term follow-up, a detailed echocardiographic assessment was used. Echocardiographic assessment included measuring volume and area of the regurgitation flow, the width of vena contracta, and the regurgitation fraction. The application of high-precision 3D reconstruction opens up additional opportunities in the field of surgical treatment of the aortic root and AV pathology: advantages in choosing an individual patient-oriented surgical tactics, parameters of the implanted surgical material and/or device, and in predicting long-term results of surgical treatment.

Filippov et al. (2022) conducted a case report in Aneurysm of the aortic root accompanied by aortic insufficiency (n=1). High-precision 3-dimensional segmentation and reconstruction of the aortic root was evaluated on Anatomical and functional features of the aortic valve (echocardiographic assessment). A novel high-precision 3D reconstruction technique was successfully applied to evaluate the anatomical and functional features of the reimplanted aortic valve 18 months after the David I procedure.
