2) Adult form that sits after the aortic arch (associated with a bicuspid aortic valve)
Symptoms:
Infantile
1) Cyanosis in the lower extremities
Adult
1) HTN in the upper extremity
2) Hypotension & weak pulse in the lower extremities
3) Collateral circulation in the intercostal arteries
4) Engorged arteries
Patho:
A narrowed/pinched segment of the aorta that has two forms
1) Infantile form that sits after the aortic arch & before the PDA
(associated with PDA & Turners)
2) Adult form that sits after the aortic arch (associated with a bicuspid aortic valve)
Symptoms:
Infantile
1) Cyanosis in the lower extremities
Adult
1) HTN in the upper extremity
2) Hypotension & weak pulse in the lower extremities
3) Collateral circulation in the intercostal arteries
4) Engorged arteries
coarctation of the aorta
Describe the following for chronic rheumatic heart disease:
What is the pathophysiology?
What are the symptoms?
What is a concerning sequelae?
Patho:
Chronic inflammation in response to group A B-hemolytic strep (repeated exposures) results in scarring of the heart valves & thickening of chordae tendinea causing Mitral valve stenosis (less commonly affects the aortic)
Symptoms:
1) Mitral stenosis
2) Aortic stenosis (less common)
3) Fish mouth valve
Sequelae:
Infectious endocarditis (usually with S. viridians

Describes which condition?
chronic rheumatic heart disease
Describe the following for Bacterial endocarditis due to S. viridians:
What is the pathophysiology?
What is a symptom?
What are the associated conditions?
What is the treatment?
Patho:
Because it has low virulence it can only infect heart valves that have already been damaged especially the MITRAL valve. It grows vegetations (fibrin & platelets) on the valves to trap bacteria and cause inflammation
Symptom:
1) Mitral insufficiency (holosystolic murmur)
2) Splinter hemorrhages (nails)
3) Osler nodes (ouch)
4) Janeway lesions
5) Roth spots
Ass conditions:
Chronic rheumatic heart disease
MVP

Bacterial endocarditis infected with S viridians
Describe the following for bacterial endocarditis infected with S. aureus:
What is the pathophysiology?
What are the symptoms?
Patho:
Most common among IV drug abusers. It is very virulent so it can infect healthy heart valves (TRICUSPID). It grows vegetations which destroy the valve
Symptoms:
Symptom:
1) Tricuspid insufficiency (holosystolic murmur)
2) Splinter hemorrhages (nails)
3) Osler nodes (ouch)
4) Janeway lesions
5) Roth spots
