Valvular pathology Flashcards
Cardiomyopathy definition
heart disease resulting from abnormality in myocardium, excludes ischemic heart disease, valve related heart disease, hypertensive heart disease
Dilated cardiomyopathy -Define the macroscopic appearance of the heart
enlarged ventricle +/- atria with thinning of the wall
Name the mechanism of heart failure in dilated cardiomyopathy and myocardial pathological changes
Impaired contractility - systolic / contraction. Myocardial Pathologic Changes: Non-specific
Impaired contractility - systolic / contraction. Myocardial Pathologic Changes: Non-specific
Impaired contractility - systolic / contraction. Myocardial Pathologic Changes: Non-specific
Impaired contractility - systolic / contraction. Myocardial Pathologic Changes: Non-specific
Name several examples of associated disease processes with dilated cardiomyopathy
Idiopathic, toxic (ethanol, adriamycin), metabolic (hemochromatosis), inflammatory (sarcoidosis), traumatic or degenerative (dystrophy)
Hypertorphic cardiomyopathy -Define the macroscopic appearance of the heart and pathological changes
•Thickened interventricular septum bulges into the left ventricle outflow tract during early systole. outflow obstruction through aortic valve (~25%) / ejection murmur. Anterior leaflet of the mitral valve may also impinge on septal wall during systole. Pathologic Changes: Non-specific hypertrophy & disarray of fibers
Name the mechanism of heart failure in hypertrophic cardiomyopathy
Impaired compliance - diastolic / relaxation
Name several examples of associated disease processes with hyertrophic cardiomyopathy
Genetic: Degenerative (dystrophy); metabolic (glycogen storage disease); infants of diabetic mothers
Define macroscopic appearance of heart in restrictive cardiomyopathy and pathologic changes and mechanism of failure
- Mechanism: Impaired compliance - diastolic / relaxation (filling) +/- contractility - systolic. Pathologic Changes: Infiltrative process: amyloid; leukemia. Fibrosis: radiation-induced myopathy
- Mechanism: Impaired compliance - diastolic / relaxation (filling) +/- contractility - systolic. Pathologic Changes: Infiltrative process: amyloid; leukemia. Fibrosis: radiation-induced myopathy
- Mechanism: Impaired compliance - diastolic / relaxation (filling) +/- contractility - systolic. Pathologic Changes: Infiltrative process: amyloid; leukemia. Fibrosis: radiation-induced myopathy
- Mechanism: Impaired compliance - diastolic / relaxation (filling) +/- contractility - systolic. Pathologic Changes: Infiltrative process: amyloid; leukemia. Fibrosis: radiation-induced myopathy
Name several examples of associated disease processes with restrictive cardiomyopathy
Idiopathic, Metabolic-Ischemic (amyloidosis); Traumatic (radiation); inflammatory (sarcoidosis)
Describe the anatomic finding in myofibers in the setting of hypertrophy
Hypertrophy and disarray of fibers. Same number of myocytes but more sarcomeres
Name the most common form of hypertension (~90%)
Essential (or primary) HTN is idiopathic and found in 90% of cases. Secondary HTN is related to renal disease, endocrine disease or cardiovascular disease
Name several renal disease processes that manifest as systemic hypertension
Chronic renal disease (trauma), glomerulonephritis (inflam), vasculitis (inflam), renal artery stenosis (trauma), polycystic renal disease (developmental), neoplasm
Name a developmental process involving the aorta that leads to hypertension
Coarctation of arota - developmental
Name at least one hypertension-associated disease process in each of the following organs a. Pituitary b. Thyroid c. Adrenal
Pituitary- acromegaly (neoplasm). Thyroid: hyperthyroidism- thyrotoxicosis (inflam). Adrenal: adenoma- aldosterone (neooplasm) and pheochromocytoma (neoplasm)
Complications of systemic HTN
- Atherosclerosis 2. Cerebral vascular disease: a. Ischemic: arteriolosclerosis, b. Hemorrhage
