What are five causes of RCM?
|
amyloidosis
sarcoidosis endomyocardial fibrosis (endocardial thickening) hemochromatosis (excess iron) glycogen storage (pompes disease) |
|
|
What is the most common rcm?
|
amyloidosis
|
|
|
What two causes are considered infiltrative?
|
amyloidosis and sarcoidosis
|
|
|
What is abnormal in amyloidosis and how is it sometimes described?
|
proteins
a translucent waxy protein build up on the myofibrils |
|
|
Where does the term infiltrative refer to and what results?
|
infiltrationof the myocardium resulting in rigid ventricular walls and impeded diastolic filling
|
|
|
What disease can interfere with conduction system and what results?
|
sarcoidosis
leads to AV block |
|
|
What are four physical signs of rcm?
|
fatigue
dyspnea angina syncope |
|
|
On echo, what might be seen regarding ventricles?
|
ventricular hypertrophy with small or normal ventricular cavity
|
|
|
On echo, what might be seen regarding the myocardium?
|
"ground glass" appearance
|
|
|
On echo what might be seen with endomyocardial fibrosis?
|
endocardium appears echogenic or scarred
|
|
|
What are two additional possible echo findings?
|
pericardial effusion
AV valve involvement |
|
|
What is a finding in regard to systolic function?
|
it may be normal or decreased
|
|
|
On echo, what might be a finding in regard to EF?
|
severely reduced EF
|
|
|
A restrictive cardiomyopathy has which of the following?
a) increased afterload b) decreased lv compliance c) increased preload d) decreased la pressure |
b) decreased lv compliance
|
|
|
What doppler finding in regard to diastolic function might be seen?
|
abnormal diastolic filling patterns of AV valves
|
|
|
What is another doppler finding in regard to AV valves?
|
reduced AV flow velocities with atrial contraction and less respiratory flow variation than tamponade or constrictive patients
|
|
|
What doppler finding in regard to the PV might be seen?
|
PV inflow will have low systolic velocity
