what are Spondylarthropathies
basically arthritis of the vertebral column
subtypes include:
enteropathic arthritis (EA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and reactive arthritis (ReA)
what valvular disorder can be caused by Spondylarthropathies and how
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)
what is a severe sign of AR
de mussets - head bobbing (in time with heart beat as patient can feel systolic pulse due to wide pulse pressure)
early diastolic murmur is assocaited with what?
AR - intensity is increased by handgrip manoeuvre
mid-diastolic murmur = severe
what type of pulse is palpated in AR
collapsing pulse- as blood is pushed out at high pressure but leaks back into ventricles
also pulsating nail bed
what are the causes of aortic regurg - aortic root
aortic dissection
biscuspid valve - most common in developed countries
rheumatic fever - most common in developing countries
spondylarthropathies
hypertension
syphilis
marfans and EDS
what is the pharmacological management of AR
lorsartan - targeted at reducing aortic root dilation by lowering systolic bp
what type of medication is contraindicated in AR
beta blockers - they increase time in diastole thus increase regurgitation
What is the definitive management of aortic regurgitation?
aortic valve replacement
what are the criteria for aortic valve replacement
-symptomatic AR
-asymptomatic AR with reduced EF or ventricular dilation
-enlargement of ascending aorta
-infective endocarditis
diagnostic investiagtions for AR
how is AR heard the best
left sternal edge, on expiration and leaning forward
how is AS heard best
expiration, leaning forward,
what are the initial investigations for suspected AS
ecg
cxr
What is the management of symptomatic aortic stenosis?
aortic valve replacement
left ventricular hypertrophy can cause what in AS
apex displacement
Surgical management of symptomatic aortic stenosis
aortic valve replacement
young - surgical as risk is low
elderly - risk is high so transatheter aortic valve implantation
when is pulmonary stenosis loudest
on inspiration
what are the main causes of aortic stenosis (above and below 65)
above = degenerative calcification
below = bicuspid aortic valve
history of rheumatic fever is a risk factor for what valvular disease
aortic stenosis
what are the indications for surgical management of mitral regurg
reduced EF
left ventricular dilation
pulmonary artery systolic BP rise >60mmHg upon exercise testing
what might be seen on CXR of mitral regurg
cardiomegaly
what arrhythmia is associated with MR
AF - due to left atrial enlargement
what associated issues cause the symptoms of MR
left ventricular failure - dyspnoea and fatigue
pulmonary hypertension - Haemoptysis and breathlessness
AF - palpitations
