Does Dual-Source CT Imaging accurately diagnose obstructive CAD in TAVR candidates to avoid routine preprocedural coronary angiography?
TAVR planning CT has high sensitivity and negative predictive value for excluding obstructive CAD, potentially obviating the need for routine preprocedural coronary angiography in patients without CT evidence of obstruction.
TAVR planning CT has high sensitivity and NPV in excluding obstructive CAD. An additional preprocedural CC angiographic examination may not be required in TAVR candidates with a CT examination that does not show obstructive CAD.
Harris et al. (Thu,) studied this question.
