RESUMEN
Background: Congestive heart failure (CHF) is a pathological state characterized by the incapability of the heart to properly perform its essential function of delivering blood to meet the metabolic demands of the body. Case Description: The present case report concerns a 3-month-old male domestic kitten, displaying symptoms including an enlarged abdomen, emaciation, dehydration, dyspnea, rhinorrhea, and infestation with scabies. This animal, weighing 0.7 kg displays a tabby bicolor pattern. The findings gleaned from the clinical evaluation revealed the presence of a murmur upon auscultation of the cardiac region. Upon conducting an ultrasound examination, it was determined that the abdominal cavity contained a fluid accumulation known as ascites. Conclusion: The findings from the radiographic evaluation indicate that feline Hiro exhibits ascites alongside cardiomegaly, in conjunction with discernible vascular modifications characterized by both enlargements of the pulmonary arteries and veins.
