Common Clinical Scenarios
Common Clinical Scenarios
• Younger people– Functional murmur
vs MVP vs bicuspid AV
• Older people– Aortic sclerosis vs
aortic stenosis

ProbabilitiesProbabilities
• Males more commonly have aortic valve disease– Young – BAV
– Elderly - Degenerative
• Females more commonly have mitral valve disease
• MVP > rheumatic heart disease

JVP SummaryJVP Summary
• Confirm it’s the JVP you are seeing– Compressibility
– Waveform
– Manoeuvers
• Identify the height – start at 30o
• Identify the waveform

JVP InspectionJVP Inspection
• Look for descents not waves
• Descents are easier to see due to greater amplitude and frequency
• Time deepest descent with systole. This is the X’ descent

Apex: • Palpable in 1 of 5 adults age 40• Best felt with fingertips or finger pads
Normal Location:• No more than 10 cm from mid-sternal line in the
supine position • Left decubitus position not reliable for apical locationNormal Size:• No larger than 3 cm (about 2 finger breadths)
