Innocent murmur?
benign children 2-4 ICS between LSB and apex grade 1-2 decrease or absent with sitting
Physiologic Murmurs?
similar to innocent
increased flow
Physiologic Murmur causes?

pregnancy
fever
hyperthyroidism
Aortic stenosis path?
Degenerative calcification or congenital or rheumatic ( aortic leaflets
Valve stiffens, opening narrows
Right 2nd ICS
S2 may decrease
Thrill
Aortic stenosis radiates to?
carotid
Aortic stenosis character and shape?
Harsh, crescendo-decrescendo
Aortic Stenosis heard best when?
patient is sitting and leaning forward - bring aorta valve closer to the chest
Aortic Stenosis valsalva ?
↑with squatting, ↓ with standing
Pulmonic Stenosis patho?
Congenital, usually found in children
Early – pulmonic ejection sound
Severe – S2 splits, often widely - cause it is affecting the right side of the heart (inspiration affect right side of the heart)
May lead to RV failure
If loud, may have a thrill
Pulmonic Stenosis radiates to?
toward left shoulder or neck
Pulmonic stenosis character and shape?
Harsh quality
Crescendo-decrescendo
Pulmonic stenosis location?
2nd and 3rd left interspaces
HOCM path?
Massive ventricular hypertrophy
Sustained apical impulse
HOCM location?
3rd and 4th left interspaces
May have S3 and S4 at apex
HOCM radiates?
down LSB to apex
HOCM character?
Harsh
HOCM valsalva ?
Decreased with squatting
Increased with standing and Valsalva strain
Squatting _________ venous return to the heart, _________ PVR and vol in LV _________.
increases
increases
increases
Standing _________ venous return to the heart, _________ PVR and vol in LV _________.
decreases
decreases
decreases
Midsystolic Click?
Mitral Valve Prolapse
AKA Barlow’s syndrome
Mitral Valve Prolapse patho?
Leaflet redundancy and elongation of chordae tendinae
Part of valve balloons into left atrium, allows backflow of blood
Common, M=F
May be associated with a MR murmur
Mitral Valve Prolapse pitch and shape?
high pitch
crescendo
Mitral Valve Prolapse valsalva?
Squatting widens (delays) the click
Pansystolic Murmurs ( Holosystolic)?
Mitral Regurgitation
Tricuspid Regurgitation
Ventricular Septal Defect
Mitral Regurgitation patho?
Mitral valve does not fully close in systole
Back flow of blood from LV to LA
Creates volume overload on LV with subsequent dilation
Mitral Regurgitation may develop __ at apex?
S3
Mitral Regurgitation radiates to?
to left axilla
Mitral Regurgitation is ___ louder with inspiration.
NOT
Mitral Regurgitation pitch and character?
medium pitch
harsh
Tricuspid Regurgitation patho?
Backward flow from RV to RA
Most commonly due to RV failure and dilatation
Tricuspid Regurgitation location?
Heard along lower LSB
Tricuspid Regurgitation radiates to ?
RSB and xiphoid area
Tricuspid Regurgitation character?
Blowing
Tricuspid Regurgitation _________ with inspiration.
Increases
Ventricular Septal Defect patho?
Congenital defect in intraventricular septum
Flows from LV (high pressure) to RV (low pressure)
Ventricular Septal Defect location?
Left 3rd, 4th, 5th interspaces
VSD pitch, character ?
Loud, thrill, harsh, high pitch
Larger defects may be quieter
Diastolic Murmurs example?
Aortic Regurgitation (early diastolic) Mitral Stenosis (mid diastolic)
Aortic Regurgitation patho?
Aortic valve doesn’t close completely
Backward flow from aorta to LV
LV overload
May be associated with aortic flow murmur or Austin Flint murmur (mitral diastolic)
Aortic Regurgitation location?
2nd to 4th L interspaces
Aortic Regurgitation radiates to?
apex
Aortic Regurgitation pitch, character, and shape?
high to low pitch
blowing
decrescendo
Aortic Regurgitation heard best when?
patient sitting leaning forward breathe held exhaled
Mitral Stenosis patho?
Mitral valve thickens, stiffens or distorts from rheumatic fever
Does not fully open
May hear opening snap after S2
Accentuated S1
Mitral Stenosis pitch and location?
Low pitch rumble, at apex
Mitral Stenosis radiation?
none
Mitral Stenosis shape?
decrescendo
Mitral Stenosis best heard when ?
LLD
Continuous Murmurs?
Venous Hum
Pericardial Friction Rub
Patent Ductus Arteriosus
Both systolic and diastolic components - all throughout the cardiac cycle and the valve no not involved
Venous Hum patho?
Turbulence of flow in the jugular veins
Benign, more common in children
Can obliterate with pressure on jugular vein or by turning the head
Venous Hum description?
Continuous, louder in diastole
Venous Hum location?
Above medial 1/3 of clavicles, esp on R

yes listen with bell
Pericardial Friction Rub patho?
Inflammation of the pericardial sac
Pericardial Friction Rub character and pitch?

May ↑ with sitting, lean forward, hold breath in exhale
Pericardial Friction Rub location?
best heard at 3rd ICS, LSB
Patent Ductus Arteriosus patho?
