Evaluation of effective regurgitant orifice area of mitral valvular regurgitation by multislice cardiac computed tomography.
OBJECTIVE
The purpose of our study was to assess the diagnostic accuracy of multislice computed tomography (MSCT) for the identification and quantification of mitral valve regurgitation in comparison with transthoracic echocardiography (TTE).


METHODS
Twenty-six patients (15 females, 11 males with a mean age of 44.6±14.1 years) who were in follow-up with the diagnosis of mitral regurgitation and those who were referred for MSCT were enrolled. MSCT results were compared with TTE measurements.


RESULTS
The mean effective mitral regurgitant orifice area at MSCT was 23.1±13.0 mm² and at echocardiography was 24.4±16.0 mm². Bland-Altman analysis showed good agreement between the two imaging methods.


CONCLUSIONS
MSCT provides reliable and good results for the evaluation of mitral regurgitation.
