Describe ARF. Process? Pathogen? Pathognomic Histology?
|
Inflammatory response to GAS that elicits immune response and eventually becomes autoimmune. Visualization of Aschoff bodies (fibrinoid necrosis).
|
|
|
What is the treatment for ARF? What value does it preferentially injure?
|
Penicillin + Anti-inflammatories (ASA)treatment; mitral valve (often Stenosis)
|
|
|
True/False - RF is most often the cause of MS.
|
True
|
|
|
What are the common structural changes to the mitral valve in RF? At what point does MS become significant?
|
calcification, commisure fusion, thickening & shortening of the chordae tendinae. Area is less than 2 cm.
|
|
|
What condition that exists in 2 forms is often a complication in MS?
|
Pulmonary HTN: passive (PA pressure increase) or reactive (PA vessel thickening)
|
|
|
What PE findings (palpation, murmurs, S1) are apparent in mild mitral stenosis?
|
RV tap; loud S1; diastolic OS with decresendo murmur;
|
|
|
What EKG findings in MS?
|
large R in V1 (RV hypertrophy); diphasic P wave (LA dilatation)
|
|
|
True/False - Myxomatous degeneration often causes Mitral Regurgitaion and Prolapse.
|
True
|
|
|
Acute MR produces what effect on LA pressure measurements?
|
prominent v wave (often merges with c wave)
|
|
|
How do chronic MR and acute MR's clinical presentation differ?
|
acute = pulmonary congestion, dyspnea; chronic = reduced cardiac output i.e. fatigue, weakness
|
|
|
Mitral Valve Prolapse is often asymptomatic. What 2 maneuvers help distinguish the MVP murmur?
|
Squatting (increase Volume, delay occurrence); Standing (decrease volume earlier occurence)
|
