Cardiovascular system examination OSCE Guide

CARDIOVASCULAR EXAMINATION – OSCE GUIDE





Cardiovascular examination frequently appears in OSCEs.  You’ll be expected to pick up the relevant clinical signs using your examination skills. This cardiovascular examination OSCE guide provides a clear step by step approach to examining the cardiovascular system, with an included video demonstration.

Introduction
Wash hands
Introduce yourself
Confirm patient details – name / DOB
Explain the examination
Gain consent
Position the patient at 45° with their chest exposed
Ask if the patient has any pain anywhere before you begin!
General inspection
Bedside – treatments or adjuncts? – GTN spray / O/ medication / mobility aids
Comfortable at rest? – does the patient look in pain?
Shortness of breath at rest?
Malar flush – plum red discolouration of cheeks – may suggest mitral stenosis
Inspect chest – scars or visible pulsations?
Inspect legs – harvest site scars / peripheral oedema / missing limbs or toes

General inspection

Hands
Hands out with palms facing downwards
Splinter haemorrhages – reddish / brown streaks on the nail bed – bacterial endocarditis
Finger clubbing:
Ask the patient to place the nails of their index fingers back to backIn a healthy individual you should be able to observe a small diamond shaped window (Schamroth’s window)When finger clubbing is present this window is lostFinger clubbing has a number of causes including infective endocarditis and cyanotic congenital heart disease

Hands out with palms facing upwards
Colour – dusky bluish discolouration (cyanosis) suggests hypoxia
Temperature – cool peripheries may suggest poor cardiac output / hypovolaemia
Sweaty/clammy– can be associated with acute coronary syndrome
Janeway lesions – non-tender maculopapular erythematous palm pulp lesions – bacterial endocarditis
Osler’s nodes  tender red nodules on finger pulps / thenar eminence – infective endocarditis
Tar staining – smoker – risk factor for cardiovascular disease
Xanthomata – raised yellow lesions – often noted on tendons of wrist –  caused by hyperlipidaemia
Capillary refill time – normal is <2 seconds – if prolonged may suggest hypovolaemia
Inspect nails

Assess for finger clubbing

Inspect palms

Assess capillary refill time


Pulses
Radial pulse – assess rate and rhythm
Radio-radial delay:
Palpate both radial pulses simultaneouslyThey should occur at the same time in a healthy adultA delay may suggest aortic coarctation 

Collapsing pulse – associated with aortic regurgitation
First ensure the patient has no shoulder painPalpate the radial pulse with your hand wrapped around the wristRaise the arm above the head brisklyFeel for a tapping impulse through the muscle bulk of the arm as blood empties from the arm very quickly in diastole, resulting in the palpable sensationThis is a water hammer pulse and can occur in normal physiological states (fever/pregnancy), or in cardiac lesions (e.g. AR / PDA) or high output states (e.g anaemia / AV fistula / thyrotoxicosis)

Brachial pulse – assess volume and character


Blood pressure:

Measure blood pressure and note any abnormalities – hypertension / hypotension
Narrow pulse pressure is associated with aortic stenosisWide pulse pressure is associated with aortic regurgitationOften you won’t be expected to actually carry this out (due to time restraints) but make sure to mention that you’d ideally like to measure blood pressure in both arms

Carotid pulse:

Assess character and volume – e.g. slow rising character in aortic stenosisIt’s often advised to auscultate the carotid artery for a bruit before palpating, as theoretically palpation may dislodge a plaque which could lead to a stroke

Palpate radial pulse


Radial-radial delay


Palpate brachial pulse


Collapsing pulse


Measure BP


Palpate carotid pulse


Jugular venous pressure (JVP)
1. Ensure the patient is positioned at 45°
2. Ask patient to turn their head away from you
3. Observe the neck for the JVP – located inline with the sternocleidomastoid
4. Measure the JVP – number of cm from sternal angle to the upper border of pulsation
Raised JVP may indicate – fluid overload / right ventricular failure / tricuspid regurgitation

Hepatojugular reflux:

Apply pressure to the liverObserve the JVP for a riseIn healthy individuals this should last no longer than 1-2 cardiac cycles (it should then fall)If the rise in JVP is sustained and equal to or greater than 4cm this is a positive resultA positive hepatojugular reflux sign is suggestive of right sided heart failure / tricuspid regurgitation


Observe for a raised JVP


Assess for hepatojugular reflux

Face
Eyes
Conjunctival pallor – anaemia – ask patient to gently pull down lower eyelid
Corneal arcus – yellowish/grey ring surrounding the iris – hypercholesterolaemia
Xanthelasma – yellow raised lesions around the eyes –  hypercholesterolaemia

Mouth
Central cyanosis – bluish discolouration of lips / underneath tongue
Angular stomatitis – inflammation of the corners of the mouth – iron deficiency 
High arched palate – suggestive of Marfan syndrome – ↑ risk of aortic aneurysm/dissection
Dental hygiene – important if considering sources for infective endocarditis


Inspect eyes


Inspect conjunctiva


Inspect mouth


Inspect for central cyanosis


Close inspection of the chest

Scars:

Thoracotomy – minimally invasive valve surgerySternotomy – CABG / valve surgery Clavicular – pacemaker
Chest wall deformities – pectus excavatum / pectus carinatum
Visible pulsations – forceful apex beat may be visible – hypertension/ventricular hypertrophy


Inspect chest for scars


Inspect chest for deformities

Palpation
Heaves – left sternal edge – ventricular hypertrophy 
Thrills – palpable murmurs felt over aortic valve and apex beat

Apex beat:

5th intercostal space / midclavicular line kayak displacement suggests cardiomegaly Once located, count out the intercostal spaces to make it clear to the examiner you have located it


Palpate apex beat


Feel for thrills


Feel for heaves

Auscultation
Auscultate the 4 valves
Palpate the carotid pulse to determine the 1st heart sound
Auscultate using the diaphragm of the stethoscope
Aortic valve – 2nd intercostal space – right sternal edge
Pulmonary valve  2nd intercostal space – left sternal edge
Tricuspid valve  5th intercostal space – lower left sternal edge
Mitral valve – 5th intercostal space – midclavicular line (apex beat)
Repeat auscultation across the 4 valves with the bell of the stethoscope..


Auscultate aortic valve


Auscultate pulmonary valve

Auscultate tricuspid valve

Auscultate mitral valve


Repeat auscultation with bell


Radiation of the murmur

Carotid arteries (with breath held) – radiation of aortic stenosis murmur
Axilla – radiation of heart murmur into the left axilla – mitral regurgitation
Left sternal edge – aortic regurgitation

Auscultate carotid arteries

Auscultate axilla

Accentuation maneuvers

These maneuvers cause particular murmurs to become louder DURING expiration
Roll onto left side and listen to mitral area with bell during expiration – mitral murmurs (stenosis and regurgitation)
Lean forward and listen over aortic area during expiration – aortic murmurs are louder (stenosis and regurgitation)


Auscultate left sternal edge
Auscultate at heart apex using bell

To complete the examination

Auscultate lung bases – crackles may suggest pulmonary oedema – left ventricular failure
Sacral oedema / pedal oedema – may indicate right ventricular failure 
Auscultate lung bases

Check for sacral oedema

Check for pedal oedema

Thank patient
Wash hands
Summarise findings
Suggest further assessments and investigations:
Full peripheral vascular examination Record a 12-lead ECG – arrhythmias / myocardial ischaemia 
Dipstick urine – proteinuria / haematuria – hypertension
Bedside capillary blood glucose – diabetes
Perform fundoscopy – malignant hypertension – papilloedema
