Pentalogy of fallot in a Crioulo foal

Background: Cardiac anomalies account for 3.5% of congenital defects in horses. Tetralogy of Fallot (TOF) is characterized by ventricular septal defect, pulmonary stenosis, dextroposition the aorta and right ventricular hypertrophy secondary. Pentalogy of Fallot (POF) is a variation and is characterized by a defect in the right atrioventricular valve or persistence of the ductus arteriosus, in addition to the other defects observed in tetralogy. Affected animals usually have stunted growth, exercise intolerance, weakness, lethargy, cyanosis, dyspnea and syncope. The aim of this study was to describe a case of POF, as diagnosed in a Crioulo foal in southern Brazil. Case: Clinical signs were observed at the fifth day of life and were characterized by cyanosis, intense tracheal stertor, tachycardia, marked heart murmur, HR 160 bpm, RR 80 breaths/min, T 39.8C and syncope. These signs worsened with physical activity. Endoscopic evaluation of the upper airways revealed no anatomical conformation changes or tissue dysfunction. A cardiac ultrasound showed a loss of continuity of the interventricular septum, right ventricular wall thickening and a hyperechoic appearance of the area where the right atrioventricular valve (tricuspid) should be. The crises have become more severe and more frequent, the animal began to show signs of ischemia, such as loss of motor coordination and limited [...]

Desvios angulares em potros da raça crioula na região sul do RS do primeiro ao oitavo mês de vida sob manejo extensivo de criação / Angular limb deformities in crioulo foal in southern region of Rio Grande do Sul, Brazil, from the first to the eighth month of life reared under extensive management

A conformação dos membros dos potros, futuros atletas,tornou-se o alvo principal da atenção de veterinários e criadores nos últimos vinte anos, em virtude da contribuição de uma conformação deficiente na maior incidência de lesões músculo-esqueléticas e da consequentemente maior valorização econômica de indivíduos com aprumos corretos. O objetivo deste estudo é identificar as principais alterações angulares de potros da raça Crioula do primeiro ao oitavo mês de vida, destacando as de maior ocorrência. Foram avaliados 77 potros da geração 2007, escolhidos por um processo de amostragem aleatória simples de um total de 164 potros criados nas propriedades analisadas. O estudo foi realizado em duas etapas: a primeira avaliação foi feita com animais entre um e quatro meses de idade e a segunda com os mesmos potros com idade entre cinco e oito meses. Com base nas duas avaliações realizadas, o principal desvio angular observado foi o desvio medial de pinças (estevado), sendo registrado em 47 potros. A identificação de alterações de desvios angulares após o nascimento ou seu surgimento é de fundamental importância, pois permite ao médico veterinário imediata intervenção, através da realização de casqueamento e/ou alterações no manejo ou cirurgia para correção dos desvios angulares.(AU)

The conformation of the limbs of foals, future athletes, has become the focus of attention of physicians and breeders in the last 20 years due to the contribution of a poor conformation to a higher incidence of musculoskeletal disorders and consequently greater economic recovery of individuals with correct angulations. The aim of this study was to identify the main angulation disorders of Crioulo foals from the first to the eighth month of life, highlighting those that are the most frequent. A total of 77 foals of the 2007 generation were evaluated, they were chosen by a process of simple random sampling of a total of 164 foals raised on the properties analyzed. The study was conducted in two stages, the first evaluation was performed with animals within 1 and 4 months of age and the second with the same foals aged 5 and 8 months. Considering the two evaluations, the main angular defect observed was toed-in, which was observed in 47 foals. The identification of defects in angulations after birth or its appearance is extremely important to the veterinary, allowing immediate intervention by performing trimming and/or changes in management or surgery for correction of angular deviation.(AU)
