Annual Review of Medicine, 1990
This overview of heart valve prostheses is based on a current review of clinical reports and focuses on the major complications that characterize long-term valve performance: thromboembolism, thrombosis, anti-coagulant-related bleeding, and structural failure.

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.

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.

Transplantability of Heart Valves
Archives of Surgery, 1962The majority of unresolved problems in the present era of heart surgery are biologic rather than technical. The advances made in total body perfusion, the improvement in the protection of the myocardium in artificially induced cardiac arrest, etc., have made it possible to deal quite successfully with several types of congenital and acquired heart ...

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

Current Opinion in Cardiology
Purpose of review Tumours involving cardiac valves pose complex diagnostic and therapeutic challenges. In this review, we use three theoretical cases as a foundation to explore diagnostic workup, therapeutic interventions, and follow-up for both benign and malignant tumours of the heart valves.

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.

Mechanical heart valve cavitation
Expert Review of Medical Devices, 2004Cavitation was first directly related to mechanical heart valves in the mid 1980s after a series of valve failures observed with the Edwards-Duromedics valve. The damages observed indicated that cavitation could be responsible. Later, several in vitro studies visualized the bubble formation and collapse of cavitation at mechanical heart valves.
