Sixty-Four-Slice Multidetector Computed Tomography for Preoperative Evaluation of Left Ventricular Function and Mass in Patients with Mitral Regurgitation: Comparison with Magnetic Resonance Imaging and Echocardiography

OBJECTIVES: Quantitative values of left ventricular (LV) function and muscle mass in patients with mitral regurgitation are independent predictors of cardiac morbidity and mortality. The aim of this study was to prospectively evaluate whether 64-MDCT can assess the LV function in patients with mitral regurgitation with high accuracy when compared with the MRI and echocardiography results.

  1. This is an excellent study using CT for non-coronary purposes. There continues to be more interest in using CT for purposes outside the coronary artery tree due to its high spatial resolution. As radiation exposure continues to go down, the trend towards increased use of CT will likely continue.

  2. A very well designed study. However, should there be a clinical concern when the intra- and inter-observer variability coefficients for EF are 8.1 and 9.7%? Is the clinical management of a patient the same when his EF is 45% rather than 53.1%?
