Estudo do anel mitral e trígonos fibrosos com diferentes variáveis

Abstract: RESUMO: O objetivo do presente estudo é avaliar dados anatómicos importantes na cirurgia reconstrutora da valva mitral, em particular características do anel mitral (AM) relacionadas a posição e distância dos trígonos fibrosos, Além disso, buscamos correlacionar esse aspecto com as variáveis sexo, idade, grupo étnico e posição do anel aórtico em relação ao AM -"posição mitro-aórtica" . Foram estudados 96 corações humanos previamente fixados, nos quais foram realizadas duas medidas no AM, sendo a medida A a mai… Show more

“…This shows that, despite the great technological evolution and constant studies, an ideal substitute for the natural valve, either mechanical or biological, providing longevity and low thrombogenicity, is yet to be found [1][2][3][4][5] . Because of that, conservative techniques have been progressively used in patients with valvopathies in a number of centers [2][3][4][5][6] . Thus, the interest in the morphology of cardiac valves, which during the 60's and 70's was limited to the pathological features due to the large number of valvar replacements, was extended.…”

“…In children and adolescents, the prosthetic rings must be avoided for they do not allow a normal annular growth 5 , in addition to being a risk factor for distortions of the ventri- 18,28 . Without adding the fact that the annular segment of mitral-aortic continuity is capable of contracting and relaxing during the cardiac cycle in the left ventricular outlet 25,26,28 , because it is the only annular portion that does not dilate, which leads to the conclusion that at the described level no prosthetic structure should exist.…”

The long-term stability of mitral valve repair within the concept of remodeling annuloplasty does not imply the use of a rigid or flexible ring to decrease the antero-posterior ring diameter.…”
