Resumo: The relationship between the diameter of the left atrium (LA) and aorta (Ao) is considered as a prognostic factor in chronic mitral valve disease. As the left atrium is a three-dimensional structure, methods based on measurement of the chamber volume can be more accurate than linear methods.The aim of this study was to assess the feasibility of measuring LA volume with 2D echocardiography using the biplane modified Simpson (SIMP) method in 33 dogs with various classes of myxomatous mitral valve disease (MMVD), as well as to present values of LA function using the atrial diastolic and systolic volume indices (ADVI and ASVI), cardiac index (ACI) and atrial ejection fraction (AEF). We observed agreement among the LA/Ao ratio and the atrial volume indices (ADVI and ASVI) and the ACI, suggesting that the values of the variables increase as the LA/Ao ratio increases due to atrial remodeling that accompanies MMVD progression. The data demonstrated a good assessment of atrial function, allowing a better understanding of LA's role in the pathophysiology of MMVD.

Como o átrio esquerdo é uma estrutura tridimensional, os métodos baseados na mensuração de volume da câmara podem ser mais precisos que os métodos lineares. O objetivo deste estudo foi avaliar a viabilidade da mensuração do volume do AE com a ecocardiografia bidimensional, sendo usado o método Simpson biplanar em 33 cães com diversas classes da degeneração mixomatosa de valva mitral (DMVM), bem como apresentar valores de função do AE utilizando-se os índices de volumes atriais diastólico e sistólico (iVdA e iVsA), o índice cardíaco atrial (iCA) e a fração de ejeção atrial (FEA). Observou-se uma concordância entre a relação AE/Ao e os índices de volume atrial (iVdA e iVsA) e o iCA, o que sugere que os valores das variáveis aumentam à medida que a relação AE/Ao aumenta, devido à remodelação atrial que acompanha a progressão da DMVM. Os dados demonstram uma boa avaliação da função atrial e permitem uma melhor compreensão do papel do AE na fisiopatologia da DMVM.Universidade Federal de Minas Gerais2019-06-21T10:49:22Z2019-06-21T10:49:22Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCOELHO, M.
