WHAT DOES AMYLOID DO TO THE HEART evidence of cardiomegaly or systolic dysfunction?

Powerpoint presentation cardiology conference

WHAT HAPPENED TO OUR PATIENT? lead to organ dysfunction


What is amyloid
WHAT IS AMYLOID? lead to organ dysfunction

  • Nonbranching fibrillar structure, an indefinite length and a 9.5 nm width

  • Organized into a pure beta pleated sheet configuration making it highly insoluble


Powerpoint presentation cardiology conference

  • Formation is not clearly understood lead to organ dysfunction

  • But is thought that development of amyloid is a result of cleavage of the light chains of the immunoglobulins followed by aggregation of these light chains into beta pleated sheet


What is amyloidosis
WHAT IS AMYLOIDOSIS lead to organ dysfunction

  • Refers to the deposition of amyloid protein in organs and tissues

  • Protein fragments of normal antibody molecules produced by plasma cells in the bone marrow

  • Orthostatic hypotension

  • R sided 3rd heart sound is occasionally heard

  • Murmur of tricuspid or mitral regurgitation is occasionally heard

  • Amyloid infiltration of the heart results in increased echogenicity

  • Described as “granular, sparkling” appearance of the myocardium and it resulted in unusually high quality myocardial visualization

  • “sparkling pattern is not sensitive because only a minority 26% has it

  • Left ventricular thickening due to amyloid infiltration may be d misdiagnosed on echo as LEVH.

  • However, unlike true LVH, left ventricular thickening in cardiac amyloidosis is associated with a decrease in ECG voltage
