FFRCT for Complex Coronary Artery Disease Treatment Planning: New Opportunities.

Coronary computed tomography (CT) is well established for the assessment of symptomatic patients with suspected but not yet confirmed coronary artery disease with high diagnostic accuracy and risk prediction. Until recently, coronary computed tomography angiography (CTA) has played a limited role in the management of complex coronary artery disease (CAD) and in planning revascularisation strategies. With the advent of FFRCT, enabling anatomy and physiology with a single study and the ability to adjudicate lesion specific pressure loss, the potential of combined coronary CT angiography (CCTA) and fractional flow reserve (FFR) computed from non-invasive CT angiography (FFRCT) to inform treatment decision-making and help guide revascularisation has been recognised. In this review, we highlight the evolving role of FFRCT in the management of complex CAD; the opportunities, the data and the unanswered questions.
