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
