valvular disorders Flashcards

(34 cards)

1
Q

what are Spondylarthropathies

A

basically arthritis of the vertebral column
subtypes include:
enteropathic arthritis (EA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and reactive arthritis (ReA)

Q

what valvular disorder can be caused by Spondylarthropathies and how

A

aortic regurgutation
the cellular inflammation causes proliferative endarteritis (inflammation of inner lining of artery) which thickens the cusps of the aorta = aortic regurgitation (cant close properly)

Q

what is a severe sign of AR

A

de mussets - head bobbing (in time with heart beat as patient can feel systolic pulse due to wide pulse pressure)

Q

early diastolic murmur is assocaited with what?

A

AR - intensity is increased by handgrip manoeuvre
mid-diastolic murmur = severe

Q

what type of pulse is palpated in AR

A

collapsing pulse- as blood is pushed out at high pressure but leaks back into ventricles

also pulsating nail bed

Q

what are the causes of aortic regurg - aortic root

A

aortic dissection
biscuspid valve - most common in developed countries
rheumatic fever - most common in developing countries
spondylarthropathies
hypertension
syphilis
marfans and EDS

Q

what is the pharmacological management of AR

A

lorsartan - targeted at reducing aortic root dilation by lowering systolic bp

8
Q

what type of medication is contraindicated in AR

A

beta blockers - they increase time in diastole thus increase regurgitation

Q

what are the criteria for aortic valve replacement

A

-symptomatic AR
-asymptomatic AR with reduced EF or ventricular dilation
-enlargement of ascending aorta
-infective endocarditis

16
Q

left ventricular hypertrophy can cause what in AS

A

apex displacement

17
Q

Surgical management of symptomatic aortic stenosis

A

aortic valve replacement
young - surgical as risk is low
elderly - risk is high so transatheter aortic valve implantation

18
Q

when is pulmonary stenosis loudest

A

on inspiration

19
Q

what are the main causes of aortic stenosis (above and below 65)

A

above = degenerative calcification
below = bicuspid aortic valve

20
Q

history of rheumatic fever is a risk factor for what valvular disease

A

aortic stenosis

21
Q

what are the indications for surgical management of mitral regurg

A

reduced EF
left ventricular dilation
pulmonary artery systolic BP rise >60mmHg upon exercise testing

22
Q

what might be seen on CXR of mitral regurg

23
Q

what arrhythmia is associated with MR

A

AF - due to left atrial enlargement

24
Q

what associated issues cause the symptoms of MR

A

left ventricular failure - dyspnoea and fatigue
pulmonary hypertension - Haemoptysis and breathlessness
AF - palpitations

25
what is The most common ischaemic cause of acute mitral regurgitation
MI - chordae tendinae or papillary msucles can be damaged by MI
26
what is the management for AF secondary to MS
warfarin - 1st line and BB
27
S1 sound in MS
loud snap
28
what is the most common presentation of Mitral stenosis
exertional dyspnoea
29
Management options for symptomatic mitral stenosis:
diuretic (furosemide = first line) balloon valvotomy / valve replacement
30
main cause of Mitral S
rheumatic fever ( strep antigens)
31
what is the likley cause of an extra sound heard after S2
- S3 gallop, occurs at end of rapid diastolic filling within the ventricle = heart failure and increased ventricular filling pressure
32
mid-systolic click (best heard over the left 5th intercostal space)
mitral valve prolapse - leg raise and squatting improve symptoms
33
holosytolic murmur which increases with inspiration
tricuspid regurgitation - severe cases show signs of right-HF inc. JV distension, hepatosplenomegaly, ascities and peripheral odema
