The purpose of this study is to evaluate important anatomic data in the mitral valve reconstruction, specially mitral ring characteristics related to position and distance of fibrous trigone. We seek correlation of this aspect with sex, age, ethnic group and "mitral-aortic position". Ninety-four human normal hearts were analysed. Two measures were realized in mitral ring, the measure A the higher distance between the fibrous trigone and B the smaller distance: the sum of the two measures represent total perimeter of the ring. We established the relation A/B that changed 1.88 to 3.96 (2.69 + 0.38). The analysis of this relation don't present statistical difference when correlated individually with sex (p=0.6857), age (p=0.1157). However, in the association of the variables ethnic group and "mitral-aortic position" (p=0.0285), we observed that in hearts from non white persons was tendency to decrease of the relation A/B in anterior and much anterior position. In conclusion, the relation A/B is not fixed, presented variation in dependence of association by ethnic group and "mitral-aortic position".
