Factors to be considered in identifying higher risk AS patients during waiting list triage

Clinical	Investigations
NYHA class IV symptoms or rapid recent deterioration	Echo parameters – high peak and mean gradients. Low aortic valve area. Poor LV systolic function. Severe coexistent MR.
Exertional syncope	Significantly elevated NT-pro-BNP.
Previous/recent admission with decompensation (pulmonary oedema/arrhythmia)	Excessive aortic valve calcium score on CT.
Significant burden of comorbidity (coexistent cardiac disease; renal)	Deteriorating renal function.

AS, aortic stenosis; MR, mitral regurgitation.
