A guide to the radiographic identification of prosthetic heart valves.

A guide to the radiographic identification of prosthetic heart valves.

To facilitate the radiographic identification of prosthetic heart valves, radiographic silhouettes of various aortic, mitral and tricuspid valve prostheses were analyzed and shematized. Forty different prosthetic valve models (heterograft and mechanical) were obtained from seven domestic manufacturers. Each prosthesis was positioned to approximate the aortic, mitral or tricuspid valve anulus pl...

A guide to the radiographic identification of prosthetic heart valves: an addendum.

Several years ago "A Guide to the Radiographic Identification of Prosthetic Heart Valves" (Circulation 57:613, 1978) described the radiographic silhouettes of 40 different cardiac prosthesis in clinical use. Since that time a number of prostheses have been developed and introduced to clinical practice. Ten of these newer prostheses manufactured by six domestic companies were photographed and ra...

Prosthetic Aortic Heart Valves

In this review, the anatomy and structure of the aortic valve and its prostheses are comprehensively discussed. Cardiac anatomy and function, human heart valves and their prostheses are also extensively discussed. The current status of prosthetic heart valves along with the next generation of these devices is broadly deliberated. Ather promising options such astranscatheter technologies (percut...

Prosthetic heart valves.

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 practice, and this article discusses the hemody...
