Key result
Retrospectively ECG-gated dual-source CT demonstrated high diagnostic accuracy for differentiating bicuspid from tricuspid aortic valves, with an overall sensitivity of 94% and specificity of 100%.
Why the study?
Does retrospectively ECG-gated dual-source CT accurately differentiate between bicuspid and tricuspid aortic valves compared to echocardiography and surgery?

Effect estimate: Sensitivity 94%, Specificity 100%
Retrospectively ECG-gated dual-source CT is highly accurate for differentiating between bicuspid and tricuspid aortic valves, with systolic reconstructions required for valves with a raphe.

May support CT for aortic valve differentiation in select cases; leaves open prospective validation before changing practice.
Alkadhi et al. (2010) conducted an observational in Bicuspid and tricuspid aortic valves (n=94). Retrospectively ECG-gated dual-source CT vs. Echocardiography and surgery was evaluated on Differentiation between bicuspid and tricuspid aortic valves (Sensitivity 94%, Specificity 100%). Retrospectively ECG-gated dual-source CT demonstrated high diagnostic accuracy for differentiating bicuspid from tricuspid aortic valves, with an overall sensitivity of 94% and specificity of 100%.
