Can cardiac MRI accurately evaluate mitral valve stenoses?

The evaluation of mitral valve stenosis: comparison of transthoracic echocardiography and cardiac magnetic resonance.
BACKGROUND: transthoracic echocardiography (TTE) is commonly utilized to asses patients with mitral valve stenosis. Can MRI perform as well?

METHODS: Thirty-one patients with isolated mitral stenosis were included. All patients were in sinus rhythm. Planimetric mitral valve area and diastolic velocities were measured with TTE and cardiac magnetic resonance (CMR) imaging.

RESULTS: TTE and CMR results were strongly correlated.

CONCLUSION: CMR is as reliable as TTE in selected patients with mitral stenosis.

COMMENT: there were several criteria for exclusion from this study, including atrial fibrillation. These results clearly remain exploratory and not proven.
