Background: Failure of the native aortic valve and degenerative anatomy of ascending aorta in patients with previous Tirone-David operation may represent a clinical challenge, because sometimes the risk of reoperation is prohibitive.Case: We described the case of a patient suffering from severe aortic valve regurgitation and pseudoaneurysm of the aortic arch, 6 years after cardiac surgery operation. The aim of this clinical case was to assess if the complex anatomy of aortic pseudoaneurysm and aortic root geometry can be accurately reproduced from contrast-enhanced computed tomography scan into a three-dimensional (3D) printed model. Based on this procedural method, with the aid of transesophageal 3D ultrasound, we efficaciously treated the patient percutaneously with a combination of transcatheter occluder device plus microcoil embolization and transfemoral aortic valve implantation. The patient was free from complications and the need to redo cardiac surgery.Conclusion: To the best of our knowledge, this is the first description of two simultaneous complications and their staged treatment in a patient with previous aortic valve-sparing operation. This is a useful report in a single 3D model applying such specific technology to these two simultaneous clinical settings.

Objective Aortic root reoperation after aortic dissection repair sometimes requires aortic root replacement. A valve-preserving technique should be applied when the aortic cusp is normal. Valve-sparing aortic root reconstruction using the reimplantation technique resolves aortic valve regurgitation, root dilatation, and pseudoaneurysm in the proximal anastomosis. Our experience in aortic root reoperation is presented. Methods From January 2000 to March 2019, 26 patients underwent reoperative valve-sparing aortic root reconstruction using the reimplantation technique. The time from the initial operation to reoperation was 69.3 ± 51.6 months. Aortic root reoperation was required for a fragile wall at the previous proximal anastomosis or aortic root dilatation. We aimed to stabilize the aortic root without valve regurgitation. The native aortic cusp was aggressively preserved when nearly normal. Indications included root dilatation ( n = 13), pseudoaneurysm of the previous proximal anastomosis ( n = 11), and aortic valve regurgitation ( n = 4). Results There was no early postoperative mortality. Follow-up was 49 ± 47 months (range 4–161 months). The 3, 5, and 10-year survival was 88.9% ± 7.4%, 88.9% ± 7.4%, and 77.8% ± 12.2%, respectively. Freedom from recurrence of a greater than moderate degree of aortic valve regurgitation at 3, 5, and 10 years was 86.5% ± 8.9%, 86.5% ± 8.9%, and 86.5% ± 8.9%, respectively. One patient underwent aortic valve replacement for recurrent aortic valve regurgitation 15 months after the valve-sparing reoperation. Conclusions Midterm outcomes of reoperative valve-sparing aortic root reconstruction using the reimplantation technique and postoperative aortic valve performance were satisfactory.

Aim. To compare effectiveness of ultrasound, radiological and invasive methods for assessing aortic valve (AV) stenosis.Material and methods. This study included 33 patients with AV stenosis. The mean age of the patients was 71,8±6,8 years. All patients underwent standard and three-dimensional echocardiography, computed tomography, and cardiac catheterization.Results. According to two-dimensional echocardiography, the AV area averaged 0,58±0,21 mm2, according to cardiac catheterization — 0,61±0,17 mm2, according to three-dimensional transesophageal echocardiography — 1,13±0,42 mm2, and according to multislice computed tomography 0,88±0,48 mm2. The difference between the values was significant (p<0,05).Conclusion. For routine diagnosis of AV stenosis, two-dimensional echocardiography is the optimal research method. With indications for radical treatment methods, three-dimensional echocardiography or multislice computed tomography should be performed.
