title: [Assessment of the degree of severity of mitral regurgitation by the systolic inversion of the pulmonary venous flow. Transesophageal echocardiography study].
abstract: It is controversial the value of an echocardiographic mitral regurgitation evaluation based on planimetric patterns color codification area. We made this study using as alternative methods of quantification, the parameter of pulmonary venous flow, concretly maximum velocity and area of pulmonary systolic inversion venous flow. Considered the values of this related parameters to 3 crescent degrees on mitral regurgitation severity and obtained the following results: Lightness mitral insufficiency with maximum inversion area, 10 +/- 21 mm2 and maximum inversion velocity, 3.2 +/- 6 cm/seg. Moderate mitral insufficiency with maximum inversion area, 171 +/- 140 mm2 and maximum moderate velocity, 21 +/- 13 cm/seg. Several mitral insufficiency with maximum inversion area, 648 +/- 615 and maximum inversion velocity, 50 +/- 20 cm/seg. We conclude that systolic parameters of pulmonary venous flow evaluated by transesophagic echocardiography constitute considerable sensibility rules in the evaluation of severity degree in echocardiographic mitral regurgitation.
