TRABALHO DE CONCLUSÃO DE CURSO E RELATÓRIO DE ESTÁGIO OBRIGATÓRIO: Tetralogia de Fallot em canino

Abstract

The present text aims to report a case of Tetralogy of Fallot in a one-month-old male mixed-breed dog. The animal was presented at the Cor Pulmonale clinic with complaints of growth deficit compared to other puppies in the same litter, easy fatigue after exercise or periods of stress, a significant heart murmur, and dyspnea. During the consultation with a veterinary cardiology specialist, a grade 6 heart murmur was detected. Based on the history and the examinations performed, the suggestive diagnosis of congenital heart disease was confirmed after an echocardiogram. However, the animal was clinically stable, without the presence of cardiac remodeling that would justify the initiation of medication therapy. The owner was instructed to bring the patient for echocardiographic re-evaluation every 15 days to monitor disease progression and the potential need for medical intervention. At the time the case was followed during the mandatory internship, the animal remained stable without clinical manifestations. Additionally, the possibility of surgical correction was being considered.
