Heart murmurs
What are the (4) types of Systolic murmurs?
- Mitral/Tricuspid Regurgitation (MR/TR) - Aortic Stenosis (AS) - Ventricular Septal Defect (VSD) - Mitral Valve Prolapse (MVP)
What are the (2) types of Diastolic murmurs?
- Aortic Regurgitation (AR) - Mitral Stenosis (MS)
What type of murmur is continuos?
Patent Ductus Arteriosus (PDA)
Holosystolic, high-pitched “blowing murmur”
Mitral/Tricuspid Regurgitation (MR/TR)
Crescendo-Decrescendo systolic ejection murmur following Ejection Click (EC)
Aortic Stenosis (AS)
Holsystolic, Harsh-sounding murmur
VSD
Late systolic crescendo murmur with Midsystolic Click (MC)
MVP
Imediate high-pitched “blowing” diastolic Decrescendo murmur
Aortic Regurgitation (AR)
Follows opening snap (OS). Delayed reumbling late diastolic murmur
Mitral Stenosis
Continuous machine-like murmur
PDA
Where/how is Mitral regurgitation best heard?
Loudest at Apex, radiates toward axilla Enhanced by maneuvers that: - INcrease TPR (ie., squatting, hand grip) - INcrease Left Atrium return (expiration)
What are some causes of MR?
Ischemic heart disease Mitral valve prolapse Left Ventricle Dilation Infective endocarditis
Where/how is Tricuspid regurgitation best heard?
Loudest at Apex, radiates toward Rt, sternal border Enhanced by maneuvers that: - INcrease Right Atrium return (Inspiration)
What are some causes of TR?
RV Dilation Rheumatic fever Infective endocarditis
What causes the ejection click in Aortic Stenosis?
Abrupt halting of valve leaflets
Where does AS murmur radiate to?
Carotids/Heart base
What is “pulsus parvus et tardus”?
in Aortic Stenosis – Pulses are weak witha delayed peak
AS can lead to:
Syncope Angina Dyspnea on exertion “SAD”
What can cause AS?
Age-related Calcific AS Bicuspid Aortic valve
Where/how is VSD best heard?
Loudest at Tricuspid area Enhanced by: - Hand grip maneuver d/t INcreased Afterload
What is the most frequent valvular lesion?
Mitral Valve Prolapse (MVP)
Where/how is MVP best heard?
Over Apex during S2 Enhanced by: - DEcreased venous return (Valsalva) *usually benign
What can MVP predispose patient to?
Infective endocarditis
What are causes of MVP?
Myxomatous degeneration Rheumatic fever Chordae rupture
