Restrictive And Other CMO Flashcards
Characterized by increased resistance to ventricular filling due to increased myocardial stiffness, decreased compliance, or both
Restrictive CMO
The 4 classifications of RCM
- Non-infiltrative
- Infiltrative
- Storage disease
- Endomyocardial
What happens at the cellular level with RCM?
Changes to the cardiac muscle cells
What are some clinical findings with RCM?
Diastolic dysfunction, HFpEF (increased pressures)
Echo findings of RCM
- biatrial enlargement
- LVH
- normal LV chamber size
- normal systolic function in early stages
- DDFxn
Characterized by the deposition of amyloid fibrils, most common type of RCM
Amyloidosis
Amyloid ECG
Low voltage
The myocardium appears granular/speckled
Amyloidosis
Infiltrative, granulomatous disease affecting multiple organs, including the heart 25% of the time
Sarcoidosis
Iron storage disease
Hemochromatosis
A blood disorder characterized by persistently elevated blood eosinophil counts with no known cause
Hypereosinonphilic syndrome (HES)
Symmetric or asymmetric ventricular hypertrophy, conduction defects and Ao root dilatation
Fabry disease
Prominent trabeculations and deep recesses
LV non-compaction
Which symptom is a direct hemodynamic consequence of hypertrophic cardiomyopathy with a severe outflow obstruction?
- SOB
- Tachycardia
- palpitations
- syncope
Syncope/light headedness
While scanning a patient with symmetric hypertrophic CMO, you notice that the LVOT peak velocity is 1.2 m/s at rest (normal), what should you do next?
LVOT peak velocity with valsalva
