Flashcards
Aortic Stenosis Murmur
Aortic Stenosis Murmur
Systolic heart murmur, crescendo-decrescendo, heard best at right upper sternal border, radiating to carotids, associated with age-related calcification or bicuspid aortic valve.
Mitral Regurgitation Murmur
Mitral Regurgitation Murmur
Holosystolic, high-pitched blowing murmur heard best at apex, radiating towards axilla. Associated with ischemic heart disease, mitral valve prolapse, LV dilation, or rheumatic fever
Mitral Valve Prolapse Murmur
Mitral Valve Prolapse Murmur
A late crescendo murmur heard at apex, loudest just before S2, often preceded by midsystolic click; usually benign but can predispose to infective endocarditis.

Study Notes
Systolic Heart Murmurs
-
Aortic Stenosis:
- Description: Crescendo-decrescendo murmur during systole
- Location: Right upper sternal border, radiates to carotids
- Causes (Elderly): Age-related calcification
- Causes (Young): Calcification of bicuspid aortic valve
- Associated Pulse: Pulsus parvus et tardus (weak pulse with delayed peak)
- Symptoms: Syncope, angina, dyspnea on exertion
-
Mitral Regurgitation:
- Description: Holosystolic, high-pitched "blowing" murmur
- Location: Loudest at apex, radiates towards axilla
- Causes: Ischemic heart disease, mitral valve prolapse, left ventricular dilation, rheumatic fever, infective endocarditis
-
Tricuspid Regurgitation:
- Description: Holosystolic murmur, louder during inspiration
- Location: Loudest at tricuspid area
- Causes: Right ventricular dilation, infective endocarditis
-
Mitral Valve Prolapse:
- Description: Late crescendo murmur, midsystolic click after carotid pulse
- Location: Loudest at apex, loudest just before S2
- Characteristics: Usually benign, can predispose to infective endocarditis
- Causes: Rheumatic fever, chordae rupture, myxomatous degeneration
-
Ventricular Septal Defect (VSD):
- Description: Holosystolic, harsh murmur
- Location: Loudest at tricuspid area
- Characteristic: Congenital
- Note: Larger VSDs produce lower-intensity murmurs than smaller ones.
Diastolic and Continuous Murmurs
-
Aortic Regurgitation:
- Description: Early diastolic, decrescendo, high-pitched "blowing" murmur
- Location: Best heard at the apex (aortic root dilation), left sternal border (valvular disease)
- Causes: Bicuspid aortic valve, endocarditis, aortic root dilation, rheumatic fever
- Associated Pulses: Wide pulse pressure, pistol shot femoral pulse, pulsing nail bed
- Characteristic: Hyperdynamic pulse, head bobbing, can progress to left heart failure
-
Mitral Stenosis:
- Description: Follows opening snap, mid-to-late murmur, "2nd dub" rumbling or dragging
- Characteristics: Decreasing interval between S2 and opening snap correlates to increased severity.
- Causes: Sequelae of rheumatic fever
- Complications: Left atrial dilation, pulmonary congestion, atrial fibrillation, Ortner syndrome, hemoptysis, right heart failure
- Pressure difference: Left atrial pressure greater than left ventricular pressure during diastole
- Opening snap: Abrupt halt in leaflet motion after rapid opening due to leaflet tip fusion in diastole.
-
Patent Ductus Arteriosus (PDA):
- Description: Continuous, machine-like murmur
- Location: Best heard in left infraclavicular area, loudest at S2
- Causes: Congenital rubella, prematurity
-
Pulmonary Regurgitation:
- Description: Diastolic murmur, after S2 and before S1
-
Pulmonary Stenosis:
- Description: Systolic murmur
