The valves of the heart cannot regenerate spontaneously. Therefore, heart valve disease generally necessitates surgical repair or replacement of the diseased tissue by mechanical or bioprosthetic valve substitutes in order to avoid potentially fatal cardiac or systemic consequences.

The first prosthetic valve was implanted by Hufnagel in 1952 in a patient with aortic insufficiency. Since then, prosthetic valves have evolved into various mechanical and bioprosthetic shapes and sizes. Despite the excitement surrounding the current development of prosthetic heart valves, surgically implanted valves remain the mainstay of current ...

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1977
A hydroxylysine-rich type I collagen has been isolated from pepsin-digested porcine heart valve. The ratio of alpha1 to alpha2 in the isolated molecule was 2:1. The component alpha chains exhibited unusual chromatographic behavior in comparison to corresponding chains from human dermis and lathyritic rat skin collagen.

Current Opinion in Cardiology, 1993
Progress in valve repair and replacement continued over the past year. Aortic valve repair for aortic insufficiency appears promising, and aortic decalcification may still be a useful alternative in certain cases of aortic stenosis. Mitral valve repair, well accepted for myxomatous valves, presents a challenge in ischemic disease.

Valve‐in‐valve‐in‐valve: Treating endocarditis of a transcatheter heart valve
Catheterization and Cardiovascular Interventions, 2015Transcatheter heart valve endocarditis is a rare, but life threatening complication. We describe the case of a patient who was successfully treated by transcatheter aortic valve‐in‐valve‐in‐valve replacement with a favorable 1‐year outcome, despite severe early complications. © 2015 Wiley Periodicals, Inc.

Choosing A Prosthetic Heart Valve
Cardiology Clinics, 1991Although most of the available prosthetic heart valves function remarkably well, the variety of available choices attests to the inability of any single one to fulfill the requirements of the ideal valve substitute. The mechanical prostheses include the caged-ball, tilting-disc, and bileaflet valves. Tissue valves available in the United States are the

Valvular heart disease, infected valves and prosthetic heart valves
The American Journal of Cardiology, 1990The major causes of systemic embolism from valvular heart disease (mitral, aortic and mitral valve prolapse), prosthetic valves (both mechanical and tissue valves) and infected valves (endocarditis) are reviewed from the standpoint of their incidence and complications.

Partial Heart Transplant in a Neonate With Irreparable Truncal Valve Dysfunction.
Journal of the American Medical Association (JAMA)Importance The treatment of neonates with irreparable heart valve dysfunction remains an unsolved problem because there are no heart valve implants that grow.
