Hassani C, et al. - Whether routine non–ECG-gated CT images of the chest with contrast agent can predict moderate to severe tricuspid regurgitation (TR) was investigated. Participants were 674 people who had undergone echocardiography within 24 hours of CT. For these individuals, a retrospective review of their non–ECG-gated CT images of the chest was performed. Researchers reviewed CT images and recorded measurements of the tricuspid annular diameter. They found that the prediction of moderate to severe TR with a specificity of 96.5% and sensitivity of 75.7% can be enabled by measurement of the tricuspid valve annulus on routine CT of the chest, using a cut point of ≥ 41 mm. A 95.5% negative predictive value of measurements below the threshold was also reported. Routine contrast-enhanced CT images of the chest can provide measurement of the tricuspid annular diameter and when above threshold, advising further assessment with echocardiography was recommended.
