Key result
Contrast-enhanced long-axis cine CT visualizes the mitral valve with ~86% agreement to echocardiography.
Why the study?
Does contrast enhanced cine computed tomography (Cine/CT) using a new long axis view accurately image the mitral valve compared to echocardiography?
Observational (n=14)
Does contrast enhanced cine computed tomography (Cine/CT) using a new long axis view accurately image the mitral valve compared to echocardiography?
Contrast enhanced cine computed tomography using a new long axis view is a feasible modality for imaging the mitral valve and assessing left atrial function, showing good agreement with echocardiography.
May support Cine/CT as adjunct for mitral valve assessment when echo limited; leaves open diagnostic role pending larger validation.
Comparison was made between contrast enhanced cine computed tomography (Cine/CT) and echocardiography in the imaging of the mitral valve in 14 patients. The mitral valve was seen in all 14 patients by Cine/CT using a new long axis view. There was agreement with echocardiography in 12 patients. Abnormalities in mitral valve movement were detected by Cine/CT. Left atrial size and contraction was measured by Cine/CT with a difference in left atrial ejection fraction observed between 13 patients with no evidence of mitral disease and 3 patients with mitral disease.

Rees et al. (1986) conducted an observational in Mitral valve imaging (n=14). Contrast enhanced cine computed tomography (Cine/CT) using a new long axis view vs. Echocardiography was evaluated on Agreement in imaging of the mitral valve between Cine/CT and echocardiography. Contrast enhanced cine computed tomography using a new long axis view successfully visualized the mitral valve in all 14 patients, demonstrating agreement with echocardiography in 12 patients.
