Early calcific degeneration of the St. Jude Medical Epic aortic bioprosthesis

Clinical Case Reports, 2020
This report highlights the need for close surveillance of bioprosthetic valves. Unaccountable degeneration of bioprosthetic valves can develop early after implantation and usually requires replacing the failed valve with a mechanical prosthesis.

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

Transcatheter Valve-in-Valve Procedures for Bioprosthetic Valve Dysfunction in Patients With Rheumatic vs. Non-Rheumatic Valvular Heart Disease

Frontiers in Cardiovascular Medicine, 2021
Background: Bioprosthetic heart valve has limited durability and lower long-term performance especially in rheumatic heart disease (RHD) patients that are often subject to multiple redo operations.

Real-world early- to midterm outcomes of aortic valve replacement using novel tissue technology bioprosthesis at a high-volume centerCentral MessagePerspective

JTCVS Open
Objective: The INSPIRIS-RESILIA aortic valve (Edwards Lifesciences) uses a novel tissue-fixation technology to enhance the bioprosthesis's longevity. We sought to report midterm INSPIRIS-RESILIA aortic bioprosthesis performance in a large contemporary ...

Prevention by the CXCR2 antagonist SCH527123 of the calcification of porcine heart valve cusps implanted subcutaneously in rats

Frontiers in Cardiovascular Medicine, 2023
IntroductionCalcification is a main cause of bioprosthetic heart valves failure. It may be promoted by the inflammation developed in the glutaraldehyde (GA)-fixed cusps of the bioprosthesis. We tested the hypothesis that antagonizing the C-X-C chemokines

Long-Term outcomes and durability of the mitroflow aortic bioprosthesis [PDF]

, 2016
[Abstract] Background. This study aims to determine the incidence and causes of structural valve deterioration (SVD) among all models of Mitroflow bioprostheses (A12/LX/DL), as well as to define their long-term clinical and hemodynamic performance ...

Replacement of pulmonary artery trunk in sheep using tubular valved heterograft in non-aldehydic preservation [PDF]

, 2012
INTRODUCTION: The cardiac bioprostheses are related to thromboembolic events, infectious and degenerative diseases. Wear is mainly attributed to the denaturation of collagen. Glutaraldehyde, the predominant method of preservation of bioprostheses, favors

Abdominal wall repair with acellular bovine pericardial membranes - Part I - Clinical and radiological findings [PDF]

Revista Brasileira de Cirurgia Plástica
Introduction: Reducing recurrence rates significantly, the use of biomaterials as “reinforcement meshes” in the repair of different abdominal wall defects has become an almost mandatory routine for the success of these repairs.
