Experience with the Mitroflow aortic bioprosthesis [PDF]

The Journal of Thoracic and Cardiovascular Surgery, 1994
From October 1985 to May 1990, the Mitroflow bovine pericardial valve was placed in the aortic position in 168 patients (97 men, 71 women) with a mean age of 69.7 years. Eighty-nine patients had isolated aortic valve replacement, and 79 had aortic valve replacement and additional procedures.

Conduit-on-valve replacement of a degenerated mitral bioprosthesis with a bioprosthesis [PDF]

The Annals of Thoracic Surgery, 2003
Explantation of a degenerated mitral bioprosthesis with reimplantation of a new bioprosthesis is time-consuming and can be associated with several life-threatening complications. We developed a technique to simplify this procedure and avoid the complications by attaching a new bioprosthesis supported by a pericardium-covered Dacron tube to the intact ...

Restoration of a Stuck Leaflet. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Severe aortic regurgitation (AR) for a leaflet malfunction after transcatheter aortic valve implantation (TAVI) is a dreadful complication that can lead even to cardiogenic shock. New valve's design has reduced the rate of paravalvular regurgitation, however central regurgitation is still a challenging complication.

Sutureless aortic bioprosthesis [PDF]

Interactive CardioVascular and Thoracic Surgery, 2017
Aortic valve replacement (AVR) is the treatment of choice for aortic valve disease, with excellent results reported in the short- and long-term follow-up. Due to the increasing number of patient comorbidities and older age, various technical alternatives have been developed such as transcatheter aortic valve implantation and, more recently, sutureless ...

Bicuspid mitral bioprosthesis. [PDF]

Thorax, 1981
A bicuspid mitral bioprosthesis was prepared by mounting glutaraldehyde-processed porcine pericardium onto commercially available Brownlee-Yates stents. The bioprostheses were inserted into 17 dogs. Haemodynamic performance and long-term function of the valve was assessed.

European experience with the Mosaic bioprosthesis [PDF]

The Journal of Thoracic and Cardiovascular Surgery, 2002
The purpose of this study was to prospectively evaluate the clinical and hemodynamic performance of the Mosaic bioprosthesis (Medtronic, Inc, Minneapolis, Minn).The stented porcine bioprosthesis combines the amino-oleic acid antimineralization treatment and the zero-pressure differential fixation technique for improved tissue durability.

Benefits and Pitfalls of the Perceval Sutureless Bioprosthesis [PDF]

Frontiers in Cardiovascular Medicine, 2022
Objective: To highlight the main target points covered by clinical studies on the Perceval sutureless valve for surgical aortic valve replacement (SAVR) and raise a point of discussion for further expansion of its use when compared with stented bioprostheses (SB) and transcatheter aortic valve replacement (TAVR).Methods: We reviewed clinical trials and

Is distortion of the bioprosthesis ring a risk factor for early calcification ?

Journal of Cardiothoracic Surgery, 2010
Background As the population ages, bioprosthesis are increasingly being used in cardiac valve replacement. Pericardial bioprosthesis combine an excellent hemodynamic performance with low thrombogenicity, but valve failure associated with calcification ...

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 survival after aortic valve replacement with the Mitroflow bioprosthesis : a comparative study [PDF]

, 2019
Background Recent case reports of early structural degeneration of the Mitroflow valve have cast doubts on the suitability of this bioprosthesis, particularly in the smaller sizes, and in younger patients.
