1
Q

Crescendo-decrescendo systolic ejection murmur.

A

Aortic Stenosis

2
Q

LV&raquo_space; aortic pressure during systole. Loudest at heart base; radiates to carotids.

A

Aortic Stenosis

3
Q

“Pulsus parvus et tardus”—pulses are weak with a delayed peak

A

Aortic Stenosis

4
Q

Can lead to Syncope, Angina, and Dyspnea on exertion (SAD)

A

Aortic Stenosis

5
Q

Often due to age-related calcification or early-onset calcification of bicuspid aortic valve.

A

Aortic Stenosis

6
Q

Holosystolic, high-pitched “blowing murmur.”

A

mitral or tricuspid regurg

7
Q

loudest at apex and radiates toward axilla.

A

Mitral Regurg

8
Q

often due to ischemic heart disease (post-MI), MVP, LV dilatation

A

Mitral Regurg

9
Q

loudest at tricuspid area and radiates to right sternal border.

A

Tricuspid Regurg

10
Q

commonly caused by RV dilatation.

A

Tricuspid Regurg

11
Q

Rheumatic fever and infective endocarditis can cause (two murmurs) what are they?

A

Mitral or Tricuspid Regurg

12
Q

Late systolic crescendo murmur with midsystolic click (MC; due to sudden tensing of chordae tendineae

A

Mitral valve prolapse (MVP)

13
Q

Most frequent valvular lesion

A

Mitral valve prolapse (MVP)

14
Q

Best heard over apex. Loudest just before S2. Usually benign

A

Mitral valve prolapse (MVP)

15
Q

Can predispose to infective endocarditis

A

Mitral valve prolapse (MVP)

16
Q

Can be caused by myxomatous degeneration (1° or 2° to connective tissue disease such as Marfan or Ehlers-Danlos syndrome), rheumatic fever, chordae rupture

A

Mitral valve prolapse (MVP)

17
Q

Holosystolic, harsh-sounding murmur. Loudest at tricuspid area.

A

VSD

18
Q

High-pitched “blowing” early diastolic decrescendo murmur.

A

Aortic Regurgitation

19
Q

Long diastolic murmur and signs of hyperdynamic pulse when severe and chronic causing head bobbing

A

Aortic Regurgitation

20
Q

Often due to aortic root

dilation, bicuspid aortic valve, endocarditis, rheumatic fever.

A

Aortic Regurgitation

21
Q

Progresses to left HF.

A

Aortic Regurgitation

22
Q

Follows opening snap (OS; due to abrupt halt in leaflet motion in diastole, after
rapid opening due to fusion at leaflet tips).

A

Mitral Stenosis

23
Q

Delayed rumbling late diastolic murmur ( decreased interval between S2 and OS correlates with increased severity).

A

Mitral Stenosis

24
Q

LA&raquo_space; LV pressure during diastole.

A

Mitral Stenosis

25
Q

Often occurs 2° to rheumatic fever

A

Mitral Stenosis

26
Q

Continuous machine-like murmur loudest at S2

A

PDA

27
Q

Often due to congenital rubella or prematurity. Best heard at left infraclavicular area.

A

PDA

28
Q

BEDSIDE MANEUVER:

Inspiration (increased venous return to right atrium)

A

increased intensity of right heart sounds

29
Q

BEDSIDE MANEUVER:

Hand grip (increased afterload)

A

increased intensity of MR, AR, VSD murmurs

decreased in hypertrophic cardiomyopathy murmurs

MVP: later onset of click/murmur

30
Q

BEDSIDE MANEUVER:

Valsalva (phase II), standing up (decreased preload)

A

decreased intensity of most murmurs (including AS)
BUT increased intensity of hypertrophic cardiomyopathy murmur

MVP: earlier onset of click/murmur

31
Q

BEDSIDE MANEUVER:

Rapid squatting (increase venous return, increase preload)

A

decreased intensity of hypertrophic cardiomyopathy murmur and increased intensity of AS murmur

MVP: later onset of click/murmur

32
Q

Wide fixed splitting of the second heart sound. Can lead to chronic pulmonary hypertension

A

ASD: chronic pulm HTN will lead to L–> R shunting and Eisenmenger syndrome
