What is cardio myopathy?
disease of myocardium
Cardiomyopathy is a disease of the heart muscle that makes it easier for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure.
Dilated CMO (aka: congestive CMO) is the most common CMO.
T or F ?
T
Hypertrophic Cardiomyopathy (HCMO) etiology
idiopathic
genetic/gene mutations cause the heart muscle to grow abnormally thick
Sarcoidosis is multisystem granulomatous disease; involves the heart in about 25% of cases and occurs in twice as many females as males
T or F ?
T
4 Infiltrative Disorders associated with restrictive cardiomyopathy.
- amyloidosis: *most common. Extracellular deposition of amyloid protein in multiple organ systems *Uniform “sparkling”, “ground glass” granular myocardial appearance
-
sarcoidosis: multisystem granulomatous disease causing progressive heart failure *about 25% of cases and occurs in twice as many females
as males - Hurler syndrome: lack an enzyme that the body needs to digest sugar. As a result, undigested sugar molecules build up in the body, causing progressive damage to the brain, heart, and other organs.
- Goucher disease: missing an enzyme that breaks down lipids. Lipids start to build up in certain organs such as your spleen and liver.
Uniform “sparkling”, “ground glass” granular myocardial appearance describes dilated cardiomyopathy.
T or F
F
Restrictive/Infiltrative Cardiomyopathy is the __________common of all types of cardiomyopathy.
least
_______________ is a hereditary factor associated with infiltrative/restrictive CM and typically occurs early in life.
Characteristics are: excessive glycogen storage in tissues; heart becomes enlarged and heavily thickened; and is autosomal recessive.
Pompes
List 4 storage disorders associated with restrictive cardiomyopathy.
-
Farby disease: a rare genetic disease with a deficiency of
an enzyme called alpha-GAL. A lipid storage disorder that
is X-linked and affects mainly males. -
Danon disease: a metabolic disorder (glycogen storage
disease); X-linked; associated with CM, muscle weakness,
intellectual disability; LV hypertrophy with depressed EF -
Oxalosis- a metabolic disorder; causes kidney stones; renal
failure-Thickening of bilateral walls with speckling - Hemochromatosis: causes your body to absorb too much iron from the food you eat. Excess iron is stored in your organs, especially your liver, heart and pancreas.
Reduced systolic function; decreased EF, < 30% describes which type of cardiomyopathy?
dilated CM
An iron storage disease that affects multiple organ and tissue systems which may result in tissue damage and organ malfunction (the iron is stored within the cardiac cell rather than extracellular) is ______________________.
Hemochromatosis
List 4 causes of Dilated Cardiomyopathy:

When discussing dynamic LVOT obstruction traits
Hydrodynamic drag forces (____________?_______________ ) describes the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe.)
Venturi effect
List 4 conditions associated with SAM:
- Hypertrophic cardiomyopathy
- Left ventricular hypertrophy
- Infiltrative cardiomyopathies with septal involvement
- Hypercontractile states
- Mechanical causes
What is SAM?
Systolic anterior motion of MV leaflet
_____________ is a rare, genetic, recessive disease originates from mutations in the “coding” of the mitochondria.
Both parents must have the dominant trait for a 25% chance of passing to offspring.
Friedreich’s Ataxia
*associated with HCM
Amyloidosis is the most common infiltrative disorder.
T or F
T
Dynamic LVOT obstruction; “dagger-shaped” CW profile; mitral regurgitant (accompanying SAM) with posteriorly directed jet; relaxation abnormality / diastolic dysfunction describe which type of CM?
obstructive hypertrophic CM
Conditions that decrease preload, lower afterload, and increase contractility generally increase LVOT gradient (and the systolic murmur).
T or F
T
*Provocative maneuvers that influence LVOT gradient in HCM i.e Valsalva, Amyl nitrite
True idiopathic and familial forms of dilated cardiomyopathy are relatively rare.
T or F
T
*Secondary causes of dilated cardiomyopathy are more common = ethyl alcohol
In cases of severe dilated cardiomyopathy, the increased EPSS (increased E-point to septal separation) is indicative of increased left ventricular systolic function.
T or F
T
Hypertrophic Cardiomyopathy (HCMO) treatment
__________ is a potential complication of alcohol septal ablation
heart block
*Heart block occurs when the electrical signals from the top chambers of your heart don’t conduct properly to the bottom chambers of your heart. There are three degrees of heart block. First degree heart block may cause minimal problems, however third degree heart block can be life-threatening.
What is ASH?
asymmetric septal hypertrophy
*Normally IVS/LVPW ratio is 1/1 or 1
ASH is classified by a IVS/LVPW ratio > or = 1.3/1.0 or 1.3
ex: if the IVS = 1.8 and LVPW = 1.1, the IVS/LVPW ratio = 1.8/1.1 = 1.6 (ASH)
Formula for LA volume *Biplane method
LA volume = (0.85 × A1 × A2)/L
*A1 = LA area from 4C
*A2 = LA area from 2C
*L is the shortest of the two lengths measured in the
apical two- and four-chamber views.
AS etiologies
- degenerative/calcification *most common
- congenital (uni-, bi-, quadricuspid) *BAV - 2:1 male to female occurance
- Rheumatic
- SVAS (supra valvular AS)
MVA equation
PISA method
- Align direction of flow with insinuation beam
- Zoom view & variance off
- Change baseline/Nyquist limit low in direction of jet
