AbstractAscending aortic aneurysms often include the sinotubular junction (STJ) and extend into the root portion of the aorta. The novel surgery of the V-shape resection of the noncoronary sinus of the aortic root has been shown to be a simpler procedure, comparing with traditional surgeries such as full aortic root replacement, for patients with moderate ascending aortic aneurysm and aortic root ectasia. This novel surgery could reduce the diameter and cross-sectional area of the aortic root. However, the detailed effect on the stress field and the rupture risk of the aortic root and aneurysm has not been fully investigated. In this study, we performed patient-specific finite element (FE) analysis based on the 3D geometries of the aortic root and ascending aortic aneurysm, reconstructed directly from the clinical computed tomographic (CT) images. By comparing the pre- and post-surgery results, we investigated the influence of the V-shape surgery on the stress field and rupture risk of the aortic root, ascending aortic aneurysm and aortic arch. It was found that the surgery could significantly reduce the wall stress of the aortic root, ascending aortic aneurysm, as well the aortic arch, and hence lower the rupture risk.

Aortic Aneurysm Repair

  Introduction. Aortic valve disease is often combined with the ascending aortic aneurysm. According to a number of authors, the frequency of the diagnosis varies from 9 to 50%, and the condition requires one-stage surgical correction. Typically, in these cases, mechanical or biologic prostheses are used. The Ozaki procedure allows such operations to be performed without replacing the aortic valve with an artificial prosthesis. The aim. To analyze the results of aortic valve reconstruction using the Ozaki technique combined with ascending aortic aneurysm repair. Materials and methods. The article describes the first experience of treatment of 12 patients with aortic valve disease and ascending aortic aneurysm. All the patients underwent Ozaki procedure modified by J. Benedik with surgical correction of aneurysm of the ascending aorta and the aortic arch. Results and discussion. No deaths were observed in the postoperative period. There was no conversion to aortic valve replacement. Ultrasound imaging after 3 and 6 months revealed no aortic valve dysfunction. Clinically, patients’ well-being was satisfactory and they returned to normal life. Long-term results of these operations interventions require further study. Conclusions. Our first clinical experience showed promising short- and medium-term results. The indications for aortic valve reconstruction are the same as those for valve replacement with a bioprosthesis. Ozaki procedure can be successfully combined with ascending aortic aneurysm repair. The main advantage is the absence of a frame that does not narrow the opening area of the valve and preserves the aortic root function, which is very important for patients with a narrow aortic root.
