Lec 15 Pathology of Valvular Heart Diseases Flashcards
junction of leaflets
Commisure
opening of the valve
Annulus
Cause of chronic morbidity in endocarditis?
Thrombus formation
Most threatening cardiac problem during the
initial attack
Myocarditis
pathognomonic of myocarditis
Aschoff nodules
large macrophages with atypical rod-shaped nuclei
Anitschkow cells or caterpillar cells
Just friction rub on auscultation
Pericarditis
Order of valve involvement in valvulitis
M>A>T>P
almost exclusively post-rheumatic (post
inflammatory) 99% of the time from healed, often
recurrent valvulitis
Mitral Stenosis
T or F. Mitral valve prolapse is more common in women
T
most common predisposing condition for
bacterial endocarditis in children
Congenital heart disease
Most common predisposing condition for bacterial endocarditis in adults
MVP and CHD
T or F. In bacterial endocarditis, the mitral valve is more involved than the aortic valve.
F. The aortic valve is more involved (39-46%). Baliktad compared to RHD
Vegetations with NO organism
Marantic endocarditis
most striking cardiac lesion in Systemic lupus
erythematosus
Libman-Sacks Verrucous Vegetations
Right sided lesions found in patients with venous
catheters
Libman-Sacks Verrucous Vegetations
Type of Vegetative Endocarditis. Small/medium vegetations on either or both sides of
the valve leaflets
SLE/Libman-Sacks
Type of Vegetative Endocarditis. Small, warty tan vegetations along the line of closure
of the valve leaflets
Acute RF
Type of Vegetative Endocarditis. Bulky, friable lesions on the valve
Infective endocarditis
Type of Vegetative Endocarditis. Small/medium red/tan vegetations usually attached at
the line of closure of the valve leaflets
Non-bacterial thrombotic (marantic)
