Flashcards in Chapter 7 Cardiovascular Deck (16)
The most common congenital cardiac lesions are
left to right shunts
most common cause of cyanotic congenital heart disease. It consists of four (thus “tetra”) abnormalities
tetralolgy of fallot
narrowing, or constriction, of the aorta that most commonly occurs just beyond the branching of the blood vessels to the head and arms
coartation of the aorta
Narrowing of the coronary arteries causes oxygen deprivation of the myocardium and ischemic heart disease.
coronary artery disease
abnormal accumulation of fluid in the extravascular pulmonary tissues
is the leading cause of strokes and CHF
localized dilation of an artery that most commonly involves the aorta, especially its abdominal portion
potentially fatal complication of closed-chest trauma (rapid deceleration, blast, and compression
traumatic rupture of the aorta
potentially life-threatening condition in which disruption of the intima (the inner layer) permits blood to enter the wall of the aorta and separate its layers
dissection of the aorta
arteries become marked by thickening, hardening, and loss of elasticity in the arterial wall
caused by the rupture of the chordae tendineae or by the dysfunction of the papillary muscles that are attached to the underside of the valve cusps and normally prevent them from swinging up into the atrium when the ventricles contract.
this condition causes left ventricular hypertrophy without dilation, which produces only some rounding of the cardiac apex on frontal chest radiographs and slight backward displacement on lateral projections
formation of nodules or vegetations on heart valves by deposits of bacteria or fungi
accumulation of fluid within the pericardial space surrounding the heart.
primarily involves the lower extremities, is the major source of potentially fatal pulmonary embolism
deep venous thrombosis
