Dual-Source CT Imaging to Plan Transcatheter Aortic Valve Replacement: Accuracy for Diagnosis of Obstructive Coronary Artery Disease

Structured PICO

Does Dual-Source CT Imaging accurately diagnose obstructive CAD in TAVR candidates to avoid routine preprocedural coronary angiography?

Population

TAVR candidates

Intervention

Dual-Source CT Imaging for TAVR planning

Comparator

Conventional coronary (CC) angiographic examination

Outcome

Accuracy (sensitivity and negative predictive value) for diagnosis of obstructive coronary artery diseasesurrogate

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.

Abstract

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.
