Heart disease Flashcards
Lub
Dub
S1-closure of mitral/tricuspid valve
S2-closure of aortic/pulmonic valve
Systolic murmurs
AS
MR (I)
TR (I)
Diastolic murmurs
AI
MS
Systolic murmur grades
I/VI: faint II/VI: obvious III/VI: loud IV/VI: thrill (pulsation) V/VI: Very Loud VI/VI: heard “across the room”
Holosystolic
Mid Systolic
Late Systolic
hear throughout from beginning to end
hear centrally
later in S1 closer to S2
MCC mitral stenosis
rheumatic heart disease
Valve is getting tighter and tighter causing reduced blood lfow
clinical presentation of MS
asymptomatic till repair is needed
LV failure then causes Dyspnea on exertion, Orthopnea
If RV becomes effected, you will see Fatigue, pulmonary edema, and ascites
stethoscope findings for MS
Opening snap of valve itself,
early to mid diastolic rumble at the apex
Heard best lying on left lateral decubitus position
how to test for MS?
- echo is gold standard
- CXR shows Kerley B-lines (indicates congestion)
catheter findings for MS?
Normal >2.0
Mild: > 1.5 cm2 (Valve Area)
Moderate: 1.1-1.5 cm2
Severe: < 1.0 cm2
how to treat MS?
- prophylactic antibiotics (prosthetic valves or h/o endocarditis)
- anticoag
mechanical valves require
lifelong anticoag
mitral regurg
Valve opens and doesn’t close completely
seen in >80% of healthy adults
chronic mitral regurg can result in EF of
<50%
stethoscope mitral regurg
soft S1 and a Holosystolic (throughout S1/S2) murmur at the APEX, no snap
