title: [Anatomic study of the aortic ring position in relation to the mitral ring].
abstract: OBJECTIVE
  Evaluate the relations between aortic and mitral rings.
  
  
  METHODS
  One hundred hearts were studied, in 84% men, 61% white and 85% were between 11 and 40 years old. The commissure between non coronary/left coronary sinus in the aortic ring and the middle point between anterior (AT) and posterior trigone (PT) in the mitral ring were used as references. When these points were coincident the position was middle; when the aortic point (AP) was closer the PT the position was posterior and when the AP was closer the AT the position was anterior or much anterior.
  
  
  RESULTS
  Forty seven (47%) showed middle position, twenty seven (27%) much anterior, twenty two (22%) anterior and only four (4%) posterior. These aren't related to sex and age. The hearts of black people showed more posterior position than the others.
  
  
  CONCLUSIONS
  Variations in aortic/mitral rings relations may be observed in normal hearts.
