Assessment of left atrial function using tissue motion annular displacement in healthy dogs.

Objectives: Recently, tissue motion annular displacement by speckle tracking has been shown to be a reliable method for evaluating deformation of the left atrium in healthy dogs. The aim of this study was to investigate whether tissue motion annular displacement is a feasible alternative method for studying left atrial function.

Materials And Methods: One hundred healthy dogs were included.

Assessment of left and right ventricular systolic function in dogs with multicentric lymphoma.

Objective: Myocardial dysfunction in cardio-oncology is generally thought to be related to the cardiotoxicity of chemotherapy treatment. However, it is known that some tumors have direct effects on myocardial function. These effects have already been studied in man, but there are no publications of these of the effects in dogs.

Assessment of longitudinal systolic function using tissue motion annular displacement in dogs with degenerative mitral valve disease.

Introduction: Although degenerative mitral valve disease (DMVD) is essentially a disorder of the valve, the progression of the disease leads to structural myocardial changes that may compromise left ventricular systolic function. Tissue motion annular displacement (TMAD) is a surrogate for longitudinal fiber function based on speckle tracking assessment of the movement of the mitral annulus toward the apex during systole. The aim of this study was to evaluate longitudinal systolic function with TMAD in dogs with DMVD.

Congenital Heart Disease in Dogs: A Retrospective Study of 95 Cases.

The aim of the study was to estimate the prevalence of congenital heart diseases in dogs attending 2 veterinary hospitals in Brazil and to identify possible associations between these conditions and epidemiological characteristics. A retrospective study was carried out in the cardiology sections of 2 veterinary hospitals during a period of 70 months from January 2012 and October 2017. Of a total of 6710 dogs that attended the cardiology sections of the hospitals, 109 congenital heart diseases were identified in 95 patients, representing a prevalence of 1.
