Emergency Medicine Clinics of North America, 1994
There are tens of thousands of patients with prosthetic heart valves implanted today, and although complications are infrequent, this may not hold true as patients live longer with prosthetic valves and as more and newer valves are implanted. A familiarity with the management of such patients will aid the emergency physician in the evaluation of this ...

Primary Care: Clinics in Office Practice, 2013
Heart valve disease is often characterized by a prolonged asymptomatic period that lasts for years and presents primary care physicians with an opportunity to detect disease before irreversible heart failure or other cardiac complications develop. Acute valvular disease can masquerade as respiratory illness or present with nonspecific systemic symptoms,

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.

Cardiology Clinics, 2011
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 ...

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.

Deformation of transcatheter heart valves with mitral valve-in-valve
EuroIntervention, 2023The use of oversizing in mitral valve-in-valve (MViV) procedures can lead to non-uniform expansion of transcatheter heart valves (THV). This may have implications for THV durability.The objective of this study was to assess the extent and predictors of THV deformation in MViV procedures.We examined 33 patients who underwent MViV with SAPIEN prostheses.

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.

New England Journal of Medicine, 1996
Since the 1950s more than 80 models of prosthetic heart valves have been developed and used. More than 60,000 valve replacements are performed annually in the United States. Prosthetic heart valves may be mechanical or bioprosthetic. Mechanical valves, which are composed primarily of metal or carbon alloys, are classified according to their structure ...

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 ...

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.
