| ABSTRACT 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... |

| RESUMO A hipertensão arterial pulmonar (HAP) é uma doença complexa, caracterizada por disfunção endotelial, que resulta em remodelamento vascular pulmonar e elevação da pressão arterial pulmonar, com consequente insuficiência cardíaca direita. O speckle tracking bidimensional (2D-STE) é uma das mais recentes ferramentas da ecocardiografia, o qual tem sido empregado para avaliação mais precoce da função ventricular e do efeito da HAP sobre a função dos ventrículos esquerdo e direito. O objetivo deste estudo foi avaliar a deformação (St e StR) miocárdica radial do VE em modelo experimental de suínos com HAP induzida e tratados com angiotensina-(1-7), a fim de verificar as possibilidades desse novo fármaco nas respostas clínica e hemodinâmica, pois apresenta... |

| Mitral flow propagation velocity (Vp) is an index used to evaluate the left ventricular diastolic function. Its influence on human and small animal cardiopathies has been studied; however there are few reports evaluating this variable in domestic felines. In addition, there is a lack of studies in non-sedated healthy cats. Therefore, the purpose of this study was to establish values for Vp and its correlation with other echocardiographic indexes in non-sedated healthy cats in order to provide new perspectives related to diastolic function in this species. Twenty-six clinically healthy cats were submitted to echocardiography to assess the animals' cardiac conditions. Variables such as age, heart rate (HR), body surface area (BSA), initial (E mitral) and... |
