Valvular Disease Flashcards
When does Rheumatic Fever usually occur?
Age 5-15 years
2-4 weeks after Group A Strep infection
What happens on a cellular level to cause rheumatic fever and valvular damage?
Antibody of Group A strep cell wall reacts with valvular tissue
MAJOR criteria for diagnosis of Rheumatic Fever
Carditis - high HR, murmur, pericardial rub, CCF, cardiomegaly
Arthritis - multiple large joints
Subcutaneous Nodules - extensor joint surfaces and spine
Erythema marginatum - rash on trunk, thighs, arms
Chorea - LATE sign
MINOR criteria for Rheumatic Fever
Fever
Raised inflammatry markers
Arthralgia
Long PR interval
Previous diagnosis of Rheumatic Fever
Management of Rheumatic Fever
Bed rest whilst CRP high
Penicillin
Analgesia
Haloperidol/diazepam if chorea
How long does an acute episode of rheumatic fever usually last?
3 months
What can trigger an acute episode of rheumatic fever?

Name at least 3 causes of Mitral Regurgitation (MR)

Signs of MR on examination
AF
displaced apex beat
pansystolic murmur at apex radiating to axilla

What could you see on the ECG and CXR in MR
ECG - AF, LVH
CXR - large LA/LV, pulmonary oedema
Treatment of MR
Treat the AF
Diuretics improve symptoms
Valve replacement if severe
Causes of Mitral Stenosis
Rheumatic fever
congential
malignant carcinoid
prosthetic valve
What is the normal size of the mitral valve opening, and what size is it in symptomatic Mitral stenosis?
Normal - 4-6cm
Stenosed and symptomatic <2cm
Symptoms of mitral stenosis
SOB due to pulmonary hypertension
Haemoptysis
Chronic bronchitis type picture
Palpitations/ chest pain
In mitral stenosis the LA may be dilated and cause symptoms by compressing surrounding structures. GIve examples
Hoarseness - recurrent laryngeal nerve compression
Dysphagia - compressing oeseophagus
Bronchial obstruction - compressing left lower lobe
Signs of Mitral Stenosis
Malar flush
AF
tapping apex beat
Palpable S1
RV Heave
Opening SNAP S1
Rumbling mid diastolic murmur
What could you see on ECG and CXR in mitral stenosis
ECG - AF, RVH, Right axis deviation
CXR - Large LA, pulmonary oedema
Management of mitral stenosis
Treat AF
Diuretics for symptom control
Balloon valvuloplasty
Valvulotomy
Valve replacement
Causes of aortic stenosis
Calcification of valve
bicuspid valve (congenital)
Rheumatic fever
Symptoms of Aortic stenosis
chest pan
syncope
SOBOE
Signs of Aortic stenosis on examination
Sow-rising pulse
narrow pulse pressure
LV heave
Aortic thrill
Ejection systolic murmur radiating to carotids
What can be seen on the ECG and CXR of a patient with Aortic Stenosis?
ECG
- LVH
- Left axis deviation
- Poor R wave progression
- LBBB
- Complete AV Block
CXR
- Large left ventricle
- calcified aortic valve may be visible
- post stenotic aortic dilatation
What investigation is diagnostic of aortic stenosis (and most other vavular disease)?
ECHO
Management of aortic stenosis
Surgery (prognosis without is poor)
Transcatheter Aortic Valve Replacement (TAVI) if unfit for surgery
List some ACUTE and CHRONIC causes of aortic regurgitation
ACUTE
- Infective endocarditis
- ascending aortic dissection
- chest trauma
CHRONIC
- congenital
- connective tissue disorder
- rheumatic fever
- vasculitis
- Systemic Disease (RA, SLR, Seronegative arthritis)
- HTN
- osteogenesis Imperfecta
Symptoms of Aortic regurg
SOBOE
orthopnoea
PND
Palpitations
Angina
Syncope
CCF
Signs of aortic regurg on examination
Collapsing pulse
wide pulse pressure
displaced, hyperdynamic apex beat
high pitched, early diatsolic murmur (best heard sat forward in expiration)
Corrigans sign (AR)
Carotid pulsation
Head nodding with heart beat
de Musset’s sign
Quincke’s sign
capillary pulsations in nail beds
Name given to severe AR murmur
Austin Flint
Describe the findings on ECG and CXR in a patient with aortic regurg
ECG - LVH
CXR - cardiomegaly, dilated ascending aorta, pulmonary oedema
Management of Aortic Regurg
reduce systolic hypertension
ACEi
ECHO every 6-12 months to monitor
When would a patient with Aortic regurg need surgery?
- enlarged ascending aorta
- increasing symptoms
- enlarging LV or reduced LV function on ECHO
- infective endocarditis not responding to medical Tx
