What is aortic sclerosis?
History features for Aortic Stenosis?
- Chest pain/Angina, Dyspnoea, Syncope
- decreased exercise tolerance due to inability of heart to adeqautely increase SV to meet metabolic demands
- rheumatic fever
- risk factors similar to those of IHD (htn, ^cholesterol)
Exam features for Aortic Stenosis
Pulse: plateau or anacrotic pulse or pulse may be late peaking and of small volume
Palpation: displaced hyperdynamic apex beat, thrill over aortic area
Auscultation
- narrowly split or reveresed S2 becasue of delayed LV ejection
- Mid-systoli ejection murmur maximal over aortic area + extending to carotids
- murmur loudest with patient sitting up in full expiration
Ix for aortic stenosis
ECG: LVH + strain
CXR: normal until LV begins to fail, may see calcified aortic annulus or prominent ascending aorta from post-stenotic aortic dialtion
Echo: trileaflet vs. bileaflet aortic valve, thickening and calcification of aortic valve, decreased mobility of aortic valve leaflets, LV hypertrophy and LV systolic or diastolic dysfunction, measurement of AVA + transvalvular pressure gradients
Cardiac Cath: may be necessary when severity cannot be determined by echo
How is the severity of aortic stenosis assessed
- symptoms do not correlate well with stenosis severity, patients with severe disease can be asymptomatic
- symptoms and average time to death post onset:
> exertional angina = 5 yrs
> exertional syncope = 3 yrs
> exertional dyspnoea = 2 years - signs indicating severe AS:
> thrill in aortic area
> LV failure (very late sign)
> paradoxical splitting of S2
> late peaking murmur
> presence of S4 - Echo
AVA cm2:
> 1.5= mild
1.0-1.5= Mod
<1.0 = severe
iAVA
<0.6 = severe
Mean gradient(mmHg)
<25 =mild
25-40 =mod
>40= Severe
Jet Velocity (m/s);
mild= <3
mod= 3-4
Sev= >4
Exercise stress testing
- not suitable for symptomatic patients, may be used to evaluate asymptomatic patients, hypotension or failure to increase BP with exercise = poor prognostic finding
Stages of Aortic Stenosis
A: at risk of AS
B: Progressive AS
C1: Asymptomatic Severe AS
C2: Asymptomatic Severe AS with LV dysfunction
D1: Symptomatic Severe high gradient AS
D2: Symptomatic Severe low-flow/low-gradient AS with reduced LVEF
D3: Symptomatic severe low-gradietn AS with normal LVEF or paradoxical low-flow severe AS
What is the avg rate of haemodynamic progression in pts diagnosed with AS
Treatment of Aortic stenosis
- No medical treatment will improve or halt progression
-> avoidance of strenuous activity in severe AS
-> sodium restriction if heart failure present
-> gentle diuresis for volume overload as preload dependent
-> control hypertension but avoid vasodilators
->maintain sinus rhythm - Symptomatic patients require surgery because there is a 50% mortality rate at 2 years with medical therapy alone
-> Aortic Valve replacement is a class 1 indication for patients with:
1. symptomatic severe AS
2. asymptomatic severe AS with LVEF <50%
3. asymptomatic severe AS undergoing CABG or surgery on the aorta or other heart valves
-> TAVR has been shown to reduce mortality by 20% in patients with severe AS + coexisting conditions that exclude them as candidates for SAVR (surgical)
-> percutaneous aortic balloon valvuloplasty serves best as palliative therapy in severe symptomatic patients who are not surgical candidates + as a bridge to surgery in haemodynamicaly unstable adult patients

Examination findings for LVF vs RVF?
Criteria for LVH on ECG
Voltage Criteria
Limb Leads
- R wave in lead I + S wave in lead III > 25 mm
- R wave in aVL > 11 mm
- R wave in aVF > 20 mm
- S wave in aVR > 14 mm
Precordial Leads
- R wave in V4, V5 or V6 > 26 mm
- R wave in V5 or V6 plus S wave in V1 > 35 mm (Sokolov-Lyon criteria)
- Largest R wave plus largest S wave in precordial leads > 45 mm
Non Voltage Criteria
- Increased R wave peak time > 50 ms in leads V5 or V6
- ST segment depression and T wave inversion in the left-sided leads: AKA the left ventricular ‘strain’ pattern
