My main positive findings are: 1. XXX 2. YYY My relevant negative findings are: 1. XXX (Risk factors) 2. YYY (Signs of decompensation) 3. ZZZ (POSSIBLE associated features) Overall, this points towards a diagnosis of mitral regurgitation with no signs of decompensation

Cardiovascular examination: Case 1 – Mitral regurgitation

What is a pan-systolic murmur?

  • Lasts entire duration between S1 & S2
  • Does not change in intensity
slide-10

Cardiovascular examination: Case 1 – Mitral regurgitation

What is a pan-systolic murmur?

  • Lasts entire duration between S1 & S2
  • Does not change in intensity
slide-11
SLIDE 11

11

Cardiovascular examination: Case 1 – Mitral regurgitation

Why is mitral regurgitation associated with an irregularly irregular pulse?

  • Mitral regurgitation = MV valve doesn't close

properly

(1)

slide-12
SLIDE 12

12

Cardiovascular examination: Case 1 – Mitral regurgitation

Why is mitral regurgitation associated with an irregularly irregular pulse?

  • Mitral regurgitation = MV valve doesn’t close

properly

  • So when the LV starts to contract, blood is

regurgitated from the LV back into the LA

(1)

slide-13
SLIDE 13

13

Cardiovascular examination: Case 1 – Mitral regurgitation

Why is mitral regurgitation associated with an irregularly irregular pulse?

  • Mitral regurgitation = MV valve doesn’t close

properly

  • So when the LV starts to contract, some blood is

regurgitated from the LV back into the LA

  • Over time, LA becomes dilated

Cardiovascular examination: Case 1 – Mitral regurgitation

Why is mitral regurgitation associated with an irregularly irregular pulse?

  • Mitral regurgitation = MV valve doesn’t close

properly

  • So when the LV starts to contract, some blood is

regurgitated from the LV back into the LA

  • Over time, LA becomes dilated à LA starts to

remodel à affects the electrical conduction

  • This leads to atrial fibrillation (irregularly irregular

pulse) Summary: In chronic MR, the L atrium remodels à this affects electrical conduction through the heart

SLIDE 15

Cardiovascular examination: Case 1 – Mitral regurgitation

Please present your findings?

I performed a cardiovascular examination on this patient who has signs suggestive of MITRAL REGURIGTATION My main positive findings are:

  • I palpated an irregularly, irregular pulse, suggestive of atrial fibrillation
  • On auscultation, I could hear normal 1st & 2nd heart sounds with a systolic murmur between S1

& S2

  • The systolic murmur was:
  • Character: pansystolic
  • Region: loudest over the mitral region
  • Augmentation: end-expiration with the patient lying on their left side
  • Radiation: axilla
slide-16
SLIDE 16

16

Cardiovascular examination: Case 1 – Mitral regurgitation

Please present your findings?

My relevant negative findings are:

  • No signs of vascular risk factors e.g. tar staining, tendon xanthomata
  • No peripheral stigmata of infective endocarditis
  • No scars to suggest coronary artery bypass graft or valve replacement
  • No signs of decompensation e.g. pulmonary or peripheral oedema

This points towards a diagnosis of grade 3 mitral regurgitation complicated by atrial fibrillation

slide-17
SLIDE 17

Cardiovascular examination: Case 1 – Mitral regurgitation

What are your differentials?

1. Mitral regurgitation

  • 2. Aortic stenosis

Cardiovascular examination: Case 2 – Congestive cardiac failure

Please present your findings?

I performed a cardiovascular examination on this patient who has signs suggestive of CHRONIC HEART FAILURE My main positive findings are:

  • Tar staining
  • Finger prick marks suggesting blood glucose monitoring
  • Peripheral oedema up to knees
  • I also noticed a vertical 6cm scar on the neck along the distribution of the carotid artery

suggestive of a carotid endarterectomy scar

  • On auscultation of the lung bases: bibasal crackles
slide-26
SLIDE 26

26

Cardiovascular examination: Case 2 – Congestive cardiac failure

Please present your findings?

My relevant negative findings are:

  • No scars to suggest coronary artery bypass graft or valve replacement
  • Normal heart sounds, with no added sounds or murmurs
  • No peripheral stigmata of infective endocarditis

This points towards congestive cardiac failure

  • The presence of both pulmonary and peripheral oedema suggests an element of

decompensation

What are the possible causes of heart failure?

  • Heart failure is defined as inadequate cardiac output for the body’s

requirements

How would manage CCF?

MDT approach: GP, heart failure team (cardiologist, specialist nurses), occupational therpaist Conservative

  • Stop smoking and diabetes control
  • Healthy diet and consider fluid restriction
  • Regular exercise

Medical

  • 1st line: Beta blocker and ACEi
  • Add furosemide if evidence of fluid overload, as is the case here
  • 2nd line: add in aldosterone antagonist
  • 3rd line: consider cardiac resynchronisation therapy or implantable cardiac defibrillator

Surgery

  • Heart transplant
  • Left ventricular assist device
  • Given to patients unlikely to survive until heart donor becomes available

Respiratory examination: Case 1 – Bronchiectasis

Please present your findings?

I performed a respiratory examination on this gentleman who has signs of BRONCHIECTASIS My main positive findings are:

  • Audible productive cough
  • Long acting anti-muscarinic inhaler at the bedside
  • Digital clubbing

Respiratory examination: Case 1 – Bronchiectasis

Please present your findings?

My relevant negative findings are:

  • Reassuringly, not requiring oxygen currently
  • No CO2 retention flap
  • No signs of decompensation (e.g. cor pulmonale – raised JVP and peripheral oedema)

This points towards a diagnosis of bronchiectasis

  • The patient displayed no evident signs of an underlying cause e.g. rheumatoid arthritis
  • The commonest causes of bronchiectasis are idiopathic and post-infection, which I

suspect may well be the case in this patient
