Imaging RED FLAGS for suspicion of ATTRwt-CA in severe AS
TTE	RM	CT
RV hypertrophy Elevated filling pressures Restrictive filling pattern Reduction of peak systolic tissue velocity Thickening of the atrioventricular valves and atrial septum Biatrial dilation Mild pericardial effusion Myocardial granular sparkling Reduction of GLS Apical sparing pattern	Increase in myocardial mass Increased ECV Increase in myocardial native T1 mapping Diffuse LGE	Increased ECV Increase in myocardial iodine concentration
