Perceval sutureless bioprosthesis versus Trifecta sutured bioprosthesis for aortic valve replacement: immediate results of the Perfecta study [PDF]

introduction: the perceval sutureless biological prosthesis for aortic valve replacement has been introduced with the rationale for shortening surgical, extracorporeal circulation and aortic cross-clamping times, in order to reduce postoperative ...

Absence of prosthesis-patient mismatch with the new generation of Edwards stented aortic bioprosthesis

, 2010
Prosthesis-patient mismatch (PPM) remains a controversial issue with the most recent stented biological valves. We analyzed the incidence of PPM after implantation of the Carpentier-Edwards Perimount Magna Ease aortic valve (PMEAV) bioprosthesis and ...

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.

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.

Mitral Valve Bioprosthesis Is Safer Than Mechanical Mitral Prosthesis in Young Women.

Heart Surgery Forum, 2020
BACKGROUND The ultimate goal of mitral valve surgery in young women is to extend life expectancy and improve quality of life. Mitral valve replacement (MVR) prosthesis in middle-aged women is a difficult choice between the lifelong anticoagulation by ...

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
