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 ...

Matryoshka procedure for Valve‐in‐Valve TAVI failure

Clinical Case Reports, 2022
Valve‐in‐valve transcatheter valve implantation (ViV‐TAVI) procedures for deteriorated bioprosthesis are an established therapeutic option for high‐risk patients. The presence of the fixed sewing ring of the bioprosthesis can hamper appropriate expansion

Biomechanical analysis of novel leaflet geometries for bioprosthetic valvesCentral MessagePerspective

JTCVS Open, 2023
Objectives: Although bioprosthetic valves have excellent hemodynamic properties and can eliminate the need for lifelong anticoagulation therapy, these devices are associated with high rates of reoperation and limited durability.

Porcine or Bovine Tissue Valves: Which are Better for Surgical Aortic Valve Replacement? [PDF]

Journal of Biomedical & Clinical Research, 2023
The choice between mechanical and bioprosthetic aortic valve implants is affected by relatively clear criteria. However, the choice between porcine or pericardial valve is more complex regarding bioprosthetic devices.

Durability of a bovine pericardial aortic bioprosthesis based on Valve Academic Research Consortium-3 echocardiographic criteriaCentral MessagePerspective

JTCVS Open, 2022
Objectives: The Carpentier-Edwards Perimount Magna Ease (Edwards Lifesciences) pericardial bioprosthesis has demonstrated satisfying hemodynamics at midterm follow-up, but its durability remains unclear.

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.

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 ...
