Eur Heart JPublished

  • Single-arm feasibility study
  • central core laboratory

Authors' conclusion

CABG guided by CCTA is feasible and has an acceptable safety profile in a selected population of complex coronary artery disease.

Study context

Population
Patients with three-vessel and/or left main disease (mean anatomical SYNTAX score 43.6)
Participants
114 patients
Comparison
Coronary computed tomography angiography (CCTA)-guided coronary artery bypass grafting (CABG) without knowledge of invasive coronary angiography (ICA)
  • CCTA-guided CABGn = 114
Outcome
Feasibility: % of operations performed without access to ICA

Main finding

As reported in the abstract

Feasibility (operations performed without access to ICA)

Feasibility (unblinding ICA required in one case)

99.1% (95% CI 95.2%-100%)

Anastomosis patency on 30-day follow-up CCTA (primary safety endpoint; 102 patients [91.9%])

92.6%

Secondary outcomes

Agreement in revascularization planning

ICA- vs CCTA-Heart Team concordance 82.9%, kappa
0.58 (95% CI 0.50-0.66)
CCTA-Heart Team vs actual treatment 83.7%, kappa
0.61 (95% CI 0.53-0.68)

Safety
