Key result
64-section multidetector CT correlated strongly with MR imaging for measuring regurgitant volume (r = 0.89; 95% CI 0.81-0.94) and regurgitant fraction in isolated mitral regurgitation.
Why the study?
Does 64-section CT accurately assess the severity of isolated mitral regurgitation compared to MRI and echocardiography in patients with isolated mitral regurgitation?
Observational (n=49)
Does 64-section CT accurately assess the severity of isolated mitral regurgitation compared to MRI and echocardiography in patients with isolated mitral regurgitation?
Effect estimate: r = 0.89 (95% CI 0.81, 0.94)
p-value: p=0.56
ECG-gated 64-section CT provides highly accurate quantitative information for determining the severity of isolated mitral regurgitation, comparable to MRI and echocardiography.

Supports CT for regurgitant volume assessment in isolated MR; leaves open prospective validation versus echocardiography.
Guo et al. (2009) conducted an observational in isolated mitral regurgitation (n=49). 64-section multidetector computed tomography (CT) vs. MR imaging and echocardiography was evaluated on Regurgitant volume (RV) and regurgitant fraction (RF) (r = 0.89, 95% CI 0.81, 0.94, p=0.56). 64-section multidetector CT correlated strongly with MR imaging for measuring regurgitant volume (r = 0.89; 95% CI 0.81-0.94) and regurgitant fraction in isolated mitral regurgitation.
