Bioprosthetic Valves

Apr 10, 2019 by in CARDIOVASCULAR IMAGING Comments Off on Bioprosthetic Valves

Key Points ▪ Most bioprostheses can be identified on and localized by chest radiography. The lateral chest radiograph often assists with obviating the projection of a bioprosthesis onto the spine,…

Mechanical Prosthetic Valves

Apr 10, 2019 by in CARDIOVASCULAR IMAGING Comments Off on Mechanical Prosthetic Valves

Key Points ▪ Mechanical prostheses are evident on chest radiography. Their position is readily determined. ▪ Older models of mechanical prostheses were radiographically obvious due to the greater ferrous metal…

Prosthetic Valve Dysfunction

Apr 10, 2019 by in CARDIOVASCULAR IMAGING Comments Off on Prosthetic Valve Dysfunction

Key Points ▪ Bioprostheses may develop transvalvar or perivalvar insufficiency, and mechanical prostheses may develop thrombotic or pannus-mediated obstruction or paravalvar insufficiency. ▪ The consequences of valve prosthesis dysfunction may…

Localizing Prosthetic Valves

Apr 10, 2019 by in CARDIOVASCULAR IMAGING Comments Off on Localizing Prosthetic Valves

Key Points ▪ Radiographically apparent aortic, mitral, tricuspid, and pulmonic valve prostheses can all be identified and localized by chest radiography. Older mechanical and biological valves were easy to identify because…
