Valvular Heart disease Flashcards
What is mitral regurgitation?
Mitral valve. Regurgitation= valve doesn’t close fully due to increased stretch of papillary muscles.
Effect= BACKFLOW to pulmonary circulation
What is the main cause of Mitral regurgitation?
LV dilatation.
Some causes of LV dilatation?
- Remodelling post acute MI
- Dilated cardiomyopathy- ischaemic or non.
- Rheumatic fever
- Endocarditis
- Chordae tendineae
- Calcification
Signs + symptoms for M regurgitation?
- Symptoms
- Breathlessness
- Fatigue
- Pulmonary Oedema - Signs
- Displaced apex (axilla)
- Pan systolic murmur
Treatment for M regurgitation?
- Medication- Diuretics + ACE
- Surgical
Repair- prolapse
Replacement- degenerative - Percutaneous- infancy clip (fixes hole in heart).
What is mitral stenosis?
Tight mitral valve, which doesnt fully open.
Causes of mitral stenosis?
- Reumatic fever
- Endocarditis
Signs + Symptoms for mitral stenosis?
- Signs
- Malar flush
- Tapping apex beat
- Mid diastolic rumble. localised to apex. - Symptoms
- Breathlessness
- Fatigue
- Pulmonary oedema
- palpitations
What common heart disease can mitral stenosis be associated with?
Atrial fibrillation
Treatment for Mitral stenosis?
- Medication- diuretics, Treat AF
- Surgery- Valve replacement
- Percutaneous- balloon valvuloplasty (widening valve using balloon)
What is aortic stenosis?
Tight aortic valve, doesn’t fully open.
Main causes for aortic stenosis?
- Congenital- Bicuspid instead of tricuspid
- Age related Calcification
- Rheumatic fever
What are the signs and symptoms of it?
- Signs
- Low volume pulse
- Forceful displaced apex
- Ejection systolic murmur, radiates to carotids. - Symptoms
S-syncope
A-angina
D-dyspnoea
Treatment for aortic stenosis?
- Medical- diuretics + angina treatment
- Surgical- Valve replacement
- Percutaneous- balloon valvuloplasty
What is aortic regurgitation?
Aortic valve doesnt properly close. Backflow of blood into LV
