What is a St Jude mitral valve made of?
Table of Contents
The St. Jude Medical cardiac valve is a low-profile, bileaflet, central-flow prosthesis made of pyrolitic carbon. During a 39-month period (October 1, 1979 to December 31, 1982) a total of 169 St. Jude valves were implanted in 155 patients.
Does St Jude make a bioprosthetic valve?
The St Jude Medical Biocor porcine bioprosthesis is the precursor valve to the St Jude Medical Epic valve. The Epic valve is identical to the Biocor valve except that it is treated with Linx AC ethanol-based calcium mitigation therapy.
What is a St Jude mechanical valve?
Abstract. The St. Jude Medical cardiac valve is a low-profile, bileaflet, central-flow prosthesis made entirely of pyrolytic carbon. A total of 261 St. Jude valves were implanted in 253 patients during a 25-month period.
What is biocor valve?
Recently a stentless mitral valve (Biocor) became available for clinical use. It is a porcine mitral valve with the entire chordal apparatus, the sewing ring being reinforced by a bovine pericardial ring and the chordae being sutured together onto two pericardial patches.
Which anticoagulant is contraindicated with mechanical heart valve?
Long-term anticoagulation — A VKA is the recommended long-term anticoagulant for mechanical valves. Dabigatran is contraindicated due to inferior efficacy and safety relative to a VKA, and the other direct oral anticoagulants (DOACs) have not been adequately studied. (See ‘DOACs are not used’ below.)
How is the mitral valve replaced?
Your surgeon will remove your current mitral heart valve and replace it with a new valve. The surgery team will remove the heart-lung machine. The team will wire your breastbone back together. The team will then sew or staple the incision in your skin back together.
What is epic mitral valve made of?
EPIC™/ EPIC™ SUPRA STENTED PORCINE TISSUE VALVES. The Epic™ valve is indicated for patients requiring replacement of a diseased, damaged, or malfunctioning native aortic and/or mitral heart valve.
What is the life expectancy of a mechanical heart valve?
For example, they estimated that a 45-year-old undergoing mechanical valve replacement has a life expectancy of 19 years (compared with 34 years in the general population), and lifetime risk of thrombo-embolism, bleeding, and re-intervention of 18, 15, and 10%, respectively.
What blood thinners are used for mechanical valves?
Although low-molecular-weight heparin can be used to achieve anticoagulation, the vitamin K antagonist, warfarin, is currently the only oral anticoagulant recommended for patients with aortic and mitral mechanical heart valves.
Why do patients with mechanical heart valves require anticoagulation?
Although mechanical heart valves (MHV) are more durable than tissue valves, they are more thrombogenic. Consequently, patients with MHV require long-term anticoagulation with vitamin K antagonists, such as warfarin.
