Term
what causes continuous murmurs
Definition
PDA (Patent Ductus arteriosus)
Arteriovenous Malformation
Venous Hum
Term
Aortic stenosis --> syncope. explain mechanism
Definition
exertion causes Systemic BP drop, to compensate, CO has to increase. Stenosis prevent CO increase so due to systemic decrease BP cuases cerebral hypoperfusion
Term
systolic Aortic murmer radiates to where from aortic valvular area
Definition
to the neck. S4 gallop and RHF are common
Term
Aortic stenosis: what shape heart could show up in xray?
Definition
Boot shape
Term
what is the most common reason for aortic leaflet abnormalities?
Definition
Infective Endocarditis. (no common - anorexigenic drugs)
Term
Aortic root abnormalities causes
Definition
Marfan syndrome
HTN
Syphilis
Aortic dissection
Ankylosing spondylitis
psoriatic arthritis
Term
Sx for aortic regurg. what is the main cause of aortic regug.
Definition
Dyspnea on exertion
orthopnea
fatigue
less commonly angina
Cause: infective endocarditis (most common)
Rheumatic heart disease, bicuspid aortic valve and anorexigenic drug
Term
Austin Flint murmur is heard in what condition?
Definition
Aortic Regurg--due to aortic regurgitation , originating at the mitral valve when blood enters simultaneously from both the aorta and the left atrium;
Term
what kind of medication could be given to pt with aortic regurg?
Definition
Vasodilators: to reduce after load
Term
what is the most common cause of Mitral stenosis? most common in M or Female
Definition
Rheumatic fever. Female
Term
what are common sx in mitral stenosis?
Definition
dyspnea on exertion, orthopnea, PND, Hemoptosis (common due to the Pulmonary edema), RV failure, ascites and edema
Term
what is normal on ECG for Mitral stenosis?
tx ?
Definition
A-Fib. Anticoagulations should be given to this pt.
tx: Mitral stenosis can be prevented with appropriate use of antibiotic treatment of B hemolytic strep infections.

Asymptomatic patients do not require therapy.
Symptoms of mild dyspnea and orthopnea can be treated with diuretics alone.
Term
what happens to SV in mitral regurg?
PE would show what for MVR
Definition
decrease due to regurg flow in LA
PE: Apical impulse is displaced downward and to the left.
S1 may be softer, S2is usually physiologically split. S2 is followed by S3.
Murmer is a holosystolic apical murmer that radiates to the axilla
Term
ECG would show what in Mitral regurg
Definition
LV hypertrophy and LA abnormality
Term
mid systolic click would be heard in what condition?
Definition
Mitral valve prolapse.
Term
4 type of benign murmurs
Definition
Early to midsystolic
Soft (I-II/VI)
Vary with respiration
Normal exam and W/U
Term
5 type of pathologic murmurs
Definition
Pathologic:
All diastolic murmurs
All pansystolic murmurs
Late systolic murmurs
Very loud murmurs
Continuous murmurs
Term
in grading thrill starts from what grade
Definition
Grade IV to VI
Term
why angina happens with aortic stenosis?
Definition
Dyspnea on certion. Symptoms occur due to limited coronary blood flow reserve or due to inadequate hypertrophy allowing increased wall stress and oxygen consumption to increase
Term
steroid use could do what in valve?
Definition
calcify the valve by increase deposition of CA++ and increase infection rate of valve. (vegetative endocarditis)
Term
aortic regurgitation what happens to heart?
Definition
volume overoad in LV--> hyperthrophy to compensate volume overload
Term
on PE

Hyperactive impulse on palpation of precordium
Displacement of PMI downward and left
Diastolic blowing murmur following s2 best heard along left sternal border

what is the condition?
Definition
aortic regurgitation
Term
MVP symptoms?
Definition
palpitations,syncope,chest pain
Term
PE findings on prolapse
Definition
A mid systolic click and late systolic murmur.

Valsalva manuever causes the click to occur earlier and the murmur to be more holosystolic and louder.
Term
TX for MVP
Definition
Most patients only need to observe standard endocarditis prophalaxis
B Blockers help relieve sx of palpitations
Low dose aspirin therapy ( 81mg ) is recommended for patients with redundent leaflets to reduce risk of stroke
Term
TVR PE findings
Definition
Symptoms of R sided heart failure: acites, edema, and occaisionally right upper quadrant pain.
P.E. = JVD, hepatic enlargement and liver pulsations, parasternal lift
Term
tx for TVR
Definition
If cause is LV failure – treatment is directed toward treating LV failure. ( ie; doe, orthopnea, fatigue, edema, dyspnea, etc.)
If cause is pulmonary disease, treatment is guided toward improving lung function.
Treatment is usually medical in nature. Surgical tx usually not required. If surgery is required, valve repair is better then valve replacement.
