Incidence of valvular regurgitation and leaflet perforation by using automated titanium fasteners (CORKNOT®) in heart valve repair or replacement: less usual than reported

Journal of Cardiothoracic Surgery, 2021
Background CORKNOT® facilitates a reduction in cardiopulmonary bypass (CPB) time, aortic cross clamp (ACC) time and operative time, but reported to be associated with other complications. We aim to quantify the incidence of valvular complications related

Bioprosthetic aortic valve diameter and thickness are directly related to leaflet fluttering: Results from a combined experimental and computational modeling studyCentral MessagePerspective

JTCVS Open, 2021
Objective: Bioprosthetic heart valves (BHVs) are commonly used in surgical and percutaneous valve replacement. The durability of percutaneous valve replacement is unknown, but surgical valves have been shown to require reintervention after 10 to 15 years.

Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics

, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease.

The better substitute for tricuspid valve replacement in patients with severe isolated tricuspid regurgitation

Anatolian Journal of Cardiology, 2019
Objective: The ideal alternative for tricuspid valve replacement (TVR) in patients with severe isolated tricuspid regurgitation remains unclear. The aim of the present study was to retrospectively investigate the outcomes of using bioprosthetic and ...

Long-term survival following aortic valve replacement : the influence of age, prosthesis-patient mismatch and indexed effective orifice area [PDF]

, 2017
Background: Prosthesis-patient mismatch (PPM) has been linked to reduced long-term survival after aortic valve replacement. We studied the influence of age, PPM and indexed effective orifice area (iEOA) in this setting. Methods Patients (n=586) subjected

Structural valve deterioration in the Mitroflow biological heart valve prosthesis [PDF]

European Journal of Cardio-Thoracic Surgery, 2017
Concern has been raised regarding the long-term durability of the Mitroflow biological heart valve prosthesis. Our aim was to assess the incidence of structural valve degeneration (SVD) for the Mitroflow bioprosthesis in a nationwide study in Denmark including all patients alive in Denmark who had received a Mitroflow aortic bioprosthesis since 2000 ...

Recent developments for surgical aortic valve replacement: the concept of sutureless valve technology [PDF]

, 2013
Aortic stenosis has become the most frequent type of valvular heart disease in Europe and North America and presents in the large majority of patients as calcified aortic stenosis in adults of advanced age.
