Restrictive (infiltrative) Flashcards
What is the most common etiology of restrictive cardiomyopathy?
Amylodosis
What is amylodosis?
Infiltration of amyl proteins
What are 5 etiologies of restrictive cardiomyopathy?
-amylodosis
-sarcoidosis
-Endomyocardial fibrosis
-Hemochomatosis
-Glycogen storage (pompes disease)
What is sarcoidosis ?
Infiltration of immune cells
What is Hemochromatosis?
Excess iron
What does Endomyocardial fibrosis cause?
Endocardial thickening
What is pompes disease?
A hereditary disease that impairs the bodies ability to metabolize glycogen
Amyloid & sarcoidosis are what type of cardiac abnormalities?
Infiltrative
Infiltration of myocardium results in _____ ventricular walls which impedes _____
Rigid ; diastolic filling
Sarcoidosis may infiltrate ____ system and cause a ____ heart block
Conduction
AV
What are the 3 symptoms of restrictive cardiomyopathy?
-fatigue
-Dyspena
-angina
A restrictive cardiomyopathy has what kind of appearance?
Ground glass
True or false- systolic function may be normal or impaired with restrictive cardiomyopathy?
True
True or false - a PE may be present with restrictive cardiomyopathy?
True
With endomyocardical fibrosis the endocardium appears?
Echogenic or scarred
The “ground glass” appearance is related to?
Infiltrative myocarditis
With restrictive cardiomyopathy you’ll see impaired ____ filling patterns with the AV valves
Diastolic
With restrictive cardiomyopathy the pulmonary vein flow will have a ___ systolic velocity
Low (small S wave)
With restrictive cardiomyopathy the mitral valve flow will have a ___ atrial velocity
Low. (Small A wave)
Because the LV is thick. So the LV isn’t filling in with all the volume from the LA (diastolic dysfunction) so this causes the LA is become enlarged and the atrial kick (a wave) to be small and low
A restrictive cardiomyopathy has which of the following?
- Increased afterload
- Decreased LV compliance
- Increased preload
- Decreased LA pressure
- Decreased LV compliance
