VALVULAR DISEASE NOTES
Valvular disease is damage or a defect to one or more of the heart valves
...
Its function is to prevent
the regurgitation of blood from the aorta
back into the left ventricle
...
It is comprised of 3 half moon shaped cusps
and 3 commissures
...
AO STENOSIS:
The obstruction of blood flow across the aortic valve from the left ventricle
...
There is a build up of pressure in the LV so there is compensatory LVH
...
The LV
needs more oxygen to overcome the high afterload but oxygen demands can not be met –
leads to angina symptoms
Risk Factors:
• Hypertension
• Diabetes
• Smoking
• Hypercholesterolemia
Treatment:
Balloon valvuloplasty – Balloon inserted into heart and inflated to try and open the valve
...
Valve replacement – bio-‐prosethetic/ mechanical
TAVI – transcathater aortic valve implant, it is as an alternative to open heart surgery
AO REGURGITATION:
Diastolic flow of blood from aorta to LV due to incompetence of the valve or valvular
apparatus
