Characteristics of Dilated Cardiomyopathy
|
Increased LV size
Increased LV filling pressure N or Decreased LV compliance Decreased SV, Ejection Fraction, and CO NON-specific microscopic changes |
|
|
Characteristics of Hypertrophic Cardiomyopathy
|
N or Decrased LV size
N or Increased LV filling pressure Decreased LV compliance Increased SV and Ejection Fraction NORMAL CO Distinctive microscopic changes: whorling, branching Common, GENETICALLY INHERITED disorder Beta-blockers, Calcium inhibitors occasionally effective |
|
|
Characteristics of Restrictive Cardiomyopathy
|
N LV size
Increased LV filling pressure Decreased LV compliance Decreased SV, Ejection Fraction, and CO Most cases are specific, rarely idiopathic (mainly in kids) AMYLOID No effective treatment |
|
|
Characteristics of Obliterative Cardiomyopathy
|
SUBTYPE OF RESTRICTIVE
Decreased LV size Increased LV filling pressure Decreased LV compliance Decreased SV, Ejection Fraction, and CO No effective treatment |
|
|
Endomyocardial Fibrosis
|
Subtropical, esp. in Africa
Children and young adults May be end stage of hypereosinophilic syndrome |
|
|
Endocardial Fibroelastosis
|
LV > LA > RV > RA
Common 0 - 2 years Endocardium is 10X normal thickness!!! |
|
|
Types of inflammation in types of myocarditis
|
VIRAL -- diffuse, mononuclear with edema and necrosis
BACTERIAL -- pathcy, acute, with microabscesses AUTO-I/ALLERGIC -- diffuse, mononuclear, without necrosis |
|
|
Types of Acute Pericarditis
|
SEROUS -- uremia, auto-i disease or uknown cause; rarely significant
FIBRINOUS -- most common; "bread and butter"; MI/radiation; adhesions SUPPURATIVE -- invariably infectious; pts. are severely ill; scarring often HEMORRHAGIC -- caused by tumor or Tb; scarring inevitable CASEOUS -- necrosis WITHIN sac, Tb unless proven otherwise (chronic) |
|
|
Sign of Constrictive Pericarditis
|
Small, quiet heart with reduced output and pulse pressure
|
|
|
Myxoma
|
Most common cardiac tumor
90% ATRIAL L:R ratio is 4:1 BENIGN May fragment or embolize |
