Often associated with a thrill
Preceded by ejection click
Split S2 (widended), soft P2

Question 17

Name the cause of this murmur:

Becomes louder on inspiration (unlike MR)
Prominent v wave in jugular vein
Pulsatile liver

Answer 17

Tricuspid Regurgitation

Question 18

Mitral Valve Prolapse is associated with what connective tissue disorder

Answer 18

Marfan Syndrome

Question 19

What is the pathology of mitral valve prolapse?

Answer 19

Valve leaflets, particularly posterior are enlarged

Normal dense collagen and elastin matrix of valvular fibrosa is fragmented and replaced with loose myxomatous connective tissue

Question 20

What are the three features of “MVP syndrome”?

Answer 20

Characteristic mid-sysolic click
Palpations, fatigue, dyspnea, postural orthostasis, and anxiety
Chest pain

Question 21

Name the cause of this murmur:
Mid-systolic click, late systole
Murmur corresponds to regurgitant flow through the incompetent valve
Late systolic murmur heard best at cardiac apex (if MR present)
Click and murmur can move later in systole with maneuvers which increase LV preload (squatting)

Answer 21

Mitral Valve Prolapse

Question 22

Name the cause of this murmur:
Midsystolic murmur - Head best while supine
Usually decreases or disappears when sitting or upright
Short systolic ejection
Location: 2nd to 4th ICS between left sternal border and apex
Radiation: little
Shape: diamond
Intensity: Grade I-II, possibly III
Medium pitch
Quality: variable, often musical (“vibratory” or “musical”)

Answer 22

Innocent Murmur

Question 23

What is the most common innocent murmur of childhood?

Answer 23

Still’s murmur

Question 24

Name the cause of this murmur:
Present age 2 to adolescence
Heard along left lower and midsternal border
Musical or vibratory
Short early systolic ejection murmur
Grade I-III
Diminished with sitting/standing/Valsalva

Answer 24

Still’s murmur

Question 25

Name the cause of this murmur: Another very common murmur of childhood Usually heard after age 3 Turbulence in subclavian and jugular veins Heard in upper right and left sternal borders and in the neck Continuous musical hum More like a bruit than a murmur Grade I-II Disappears if child in supine or when jugular vein is compressed

Answer 25

Venous Hum

Question 26

Causes of aortic regurgitation

Answer 26

Question 27

Name the cause of this murmur: Soft, high-pitched diastolic decrescendo murmur heard best along 3rd LICS, LSB Early diastole Location: aortic area Radiation: no Blowing quality Patient siting, leaning forward after exhaling Other murmurs May have systolic ejection murmur at aortic area due to high flow state Low-frequency mid-diastolic rumbling at apex – Austin Flint murmur Reflects turbulence across MV during diastole Bounding pulses Hyperdynamic LV impulse PMI displaced caudally and laterally S3 – when ventricular failure occurs S4 – ventricular hypertrophy Wide pulse pressure
