Article Abstract
Aim: To evaluate prospectively the hemodynamic performance of «BiolAB Mono» stentless bioprosthesis implanted into aortic position.
Material And Methods: Twenty seven patients (mean age 71 (67; 73); 17 women) with severe aortic stenosis underwent, aortic valve replacement with «BioLAB Mono» stentless bioprosthesis from 2012 to 2014. The valves- were implanted into supraannular position using continuous polypropylene suture.
Results: In the early postoperative period 1 patient (3.7%) died for acute heart failure. The mean aortic cross-clamping time was 81 (75; 90) min. Echocardiographic peak pressure gradient were 18 (16;23) mmHg (postoperative). There were no cases of valve dysfunction In early 'postoperative period. Level of thrombocytes recovered after 1 O days postoperatively.
Conclusion: «BioLAB Mono» aortic bioprosthesis implantation. is easy and reproducible. The valve has excellent hemodynamic performance ir;i early postoperative period.

Complex Bentall Operation: Clinical Pearls to Standardize the Procedure.
Ann Thorac Surg

Division of Cardiothoracic Surgery, Department of Surgery, Westchester Medical Center, New York Medical College, Valhalla, New York; Division of Cardiac Surgery, Department of Surgery, New York Medical College, Valhalla, New York.
Background: A straightforward Bentall operation can be performed safely with low mortality, but some challenging cases require a more complex operation. We discuss here the steps of the Bentall procedure.
Methods: We reviewed specific scenarios, such as acute aortic dissection, native valve or prosthetic valve endocarditis, redo Bentall after aortic root replacement, calcified aortic root, and patients with prior coronary artery bypass grafting, mechanical aortic valve replacement, stentless aortic valve replacement, and prior extensive aortic arch repair with proximalization of neck vessels.
Transcatheter Valve-in-Valve Replacement With Balloon- Versus Self-Expanding Valves in Patients With Degenerated Stentless Aortic Bioprosthesis.

Valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has been associated with favorable outcomes in patients with degenerated stentless bioprosthesis. However, whether the outcomes after ViV TAVR for failed stentless bioprosthesis differ between balloon-expandable valves (BEVs) and self-expanding valves (SEVs) remains unknown. Therefore, we retrospectively analyzed 59 consecutive patients who underwent ViV TAVR for failed stentless bioprsothesis with BEVs (n = 42) versus SEVs (n = 17) in a single-health care system between 2013 and 2022.

Introduction: One of the most serious complications of surgical aortic valve replacement (SAVR) is stroke that can result in increased rates of complications, morbidity and mortality postoperatively. The aim of this study was to investigate incidence, risk factors and short-term outcome in a well defined cohort of SAVR-patients.
Materials And Method: A retrospective study on 740 consecutive aortic stenosis patients who underwent SAVR in Iceland 2002-2019.
Reverse-U Aortotomy (Kırali Incision) for Aortic Valvular Interventions.

Department of Cardiovascular Surgery, Kosuyolu High Specialization Education and Research Hospital, Istanbul, Turkey.
Background: Surgical incisional approach to the ascending aorta is the main strategic step during valvular and/or subvalvular aortic interventions. Classic aortotomy incisions (transverse or oblique) can be challenging and can cause suboptimal exposure of the aortic root especially for the patients with small aortic annulus or for redo coronary artery bypass patients with patent proximal grafts interposed to the ascending aorta.
Methods: The Kırali incision was used in 91 patients (including 13 reoperations) who underwent an aortic intervention for valvular and subvalvular pathologies.
VARC-3 defined outcome of valve-in-valve transcatheter aortic valve implantation in stentless compared with stented aortic bioprostheses.

Department of Internal Medicine and Cardiology, Heart Center Dresden, Technische Universität Dresden, Fetscherstr. 76, 01307, Dresden, Germany.
Background: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is a viable alternative to redo surgery in selected patients with bioprosthetic valve dysfunction. Most ViV-TAVI procedures have been performed in stented bioprosthetic valves (ST); stentless bioprostheses (SL) lack fluoroscopic markers and could be more challenging for ViV-TAVI. Data on more recent patients applying Valve Academic Research Consortium (VARC)-3 defined outcomes are scarce.
