As LV fails get less gradient across valve, under-estimating severity
AS management
-
-
Maintain
-
After load
Hypotension will reduce coronary perfusion pressure and exacerbate supply-demand relationship
-
Pathophysiology
-
-
LV remodelling
Eccentric hypertrophy and chamber enlargement
LVEDP remains relatively normal because LVEDV increases slowly
Forward flow occurs by
Peripheral vasodilation reducing SVR
Large SV to generate enough ejection fraction
Aetiology
Congenital
Connective tissue disorders
Chronic inflammation
Rheumatic disease
Chronic hypertension
Annular dilation from ageing
