Severe hemolysis with a fabric-worn cloth-covered aortic valve prosthesis
Chest
|April 1, 1975
Abstract:
A patient developed severe hemolytic anemia one year after insertion of a cloth-covered aortic valve prosthesis (Starr-Edwards No. 2320). The cloth over the three struts was disrupted but showed coverage with mostly organized collagen. Hemolysis stopped after replacement with a porcine heterograft. Fabric wear seems to augment the hemolysis in patients with cloth-covered artificial valves.

Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
