Language Literature

Sutureless and rapid-deployment bioprostheses have been introduced as alternatives to traditional prosthetic valves to reduce cardiopulmonary and aortic cross-clamp times during aortic valve replacement. These devices have also been employed in extremely demanding surgical settings, as underlined in the present review. Searches on the PubMed and Medline databases aimed to identify, from the English-language literature, the reported cases where both sutureless and rapid-deployment prostheses were employed in challenging surgical situations, usually complex reoperations sometimes even performed as bailout procedures. We have identified 25 patients for whom a sutureless or rapid-deployment prosthesis was used in complex redo procedures: 17 patients with a failing stentless bioprosthesis, 6 patients with a failing homograft, and 2 patients with the failure of a valve-sparing procedure. All patients survived reoperation and were reported to be alive 3 months to 4 years postoperatively. Sutureless and rapid-deployment bioprostheses have proved effective in replacing degenerated stentless bioprostheses and homografts in challenging redo procedures. In these settings, they should be considered as a valid alternative not only to traditional prostheses but also in selected cases to transcatheter valve-in-valve solutions.

Background The Freedom SOLO (FS) stentless bovine-pericardial prosthesis with a supra-annular implantation technique can be a viable option for patients with endocarditic annular destruction. We assessed early- and long-term outcomes following the use of this prosthesis in extensive aortic valve endocarditis. Methods From 2006 to 2016, 59 patients with extensive aortic endocarditis underwent aortic valve replacement (AVR) with FS (cumulative follow-up 263 patients-years) in three European centers; all patients presented annular tissue infection, while 54.3% of patients had annular abscess. Results Mean age was 66 ± 11 years and mean EuroSCORE I was 30.3% (standard deviation: 24.1%). In our series, 30.5% of patients had prosthetic valve endocarditis. Early mortality was 15.2% (nine patients). Estimated overall survival at 5 and 10 years was 68.9% (95% confidence interval [CI]: 62.8–75.0%) and 59.1% (95% CI: 66.8–81.2%), respectively. At 10-year survival, freedom from valve-related death was 83.7% (95% CI: 80.9–86.5%). No structural valve deterioration was reported in this series. Five patients (8.5%) had recurrent endocarditis during follow-up and two of them underwent reoperation. Survival freedom from reoperation and endocarditis at 10-year follow-up was 88.0% (CI: 80.4–95.6%) and 86.7% (CI: 80.5–92.9%), respectively. Conclusion FS stentless bioprosthesis is a valuable and simple option to achieve AVR in patients with extensive aortic annulus endocarditis. Although in this group of complex patients, early mortality remains considerably high, late survival outcomes are comparable to the more technically demanding homografts and conventional stentless bioprostheses, with low rates of endocarditis recurrence.

We analyzed 50 aortic valve replacements (AVR) with Kemerovo-AB-Neo stentless bioprostheses. Mean age was 66.75 (54 to78) years, hospital mortality rate accounted for 2%. The peak transprosthetic pressure gradient (PTPG) in patients operated for aortic stenosis came to 19.57 mm Hg. PTPG was shown to be dependent on the implantation technique; it reached 24.57 mm Hg when in order to fix the proximal line, interrupted sutures were used and ran to 175 mm Hg in the case of running sutures (р = 0.03). Helical CT confirmed fine mobility of the cardiac structures after Kemerovo-AB-Neo implantation: the aortic cross-section area varied up to 84% during the cardiac cycle. It should be noted that AVR with Kemerovo-AB-Neo stentless valves gives good clinical and hemodynamic results early after surgery. A free-hand technique of implantation should be preferred. The implantation of stentless bioprostheses retains cardiac structures mobility and natural aortic root dimensions after performing an AVR.

<p><strong>Aim.</strong> The study was designed to comparatively assess dynamic changes of the aortic root structures depending on a phase of the cardiac cycle in patients with degenerative aortic stenosis, who underwent aortic valve replacement with different types of biological prostheses.<br /><strong>Methods.</strong> This prospective parallel controlled randomized trial study was performed at Meshalkin National Medical Research Center over a period from 2011 to 2015. The inclusion criteria were severe aortic stenosis and patients’ age older than 65 years. 114 patients were randomized 1:1 in two groups: group I included 57 patients with stentless biological prostheses, while group II (control one) consisted of 57 patients with stented xenopericardial prostheses. The average age was 71 [66; 74] and 72 [69; 77] for the first and second groups, respectively (p = 0.054). All patients underwent aortic valve replacement. The operation was performed under standard normothermic cardiopulmonary bypass. The diameter of the implanted prostheses was 25 mm [24; 26] and 23 mm [21; 23] for the first and second groups, respectively (p = 0.375). An ECG-synchronized CT study of the aortic root was carried out in the postoperative period.<br /><strong>Results.</strong> An intergroup systolic/diastolic difference in the values of the cross-sectional area of the aortic root at all levels was observed in patients with stentless bioprostheses, while the control group patients (with stented bioprostheses) had no such difference at the levels of the left ventricle output tract and the fibrous ring of the aortic valve.<br /><strong>Conclusion.</strong> A stentless design of bioprostheses retains the deformational and elastic properties of the aortic root in elderly patients with aortic valve stenosis after surgical treatment.</p><p>Received 5 December 2017.
