24 healthy patients vs22 patients with functional mitral regurgitation (grade II/III) who had undergone ECG-gated computed tomography angiography were retrospectively evaluated. Mean age was 47±11 vs 63±7 years (p<0.05), male gender 75 % vs 68 % (ns), BMI 26±2.8 kg/m² versus 26±3.5 kg/m² (ns), left ventricular ejection fraction 72±6 % vs 31±9 % p<0.05). The mean mitral saddle-shaped annular area averaged 12±2 cm² in the control group, 14.6±0.52 cm² in patients with functional mitral regurgitation, the D-shaped annular area 10.3±1.6 cm² vs. 12.7±0.5 cm², respectively, being significantly different between two groups and both approaches. This study showed that there are significant differences in the mitral annular morphology between the two groups, as well as several changes between sizing approaches of the mitral annulus throughout the cardiac cycle. Our study showed that with good optimization of procedure protocol and postprocessing process, computed tomography is a feasible method for precise preprocedural evaluation of mitral valve dimensions. |
