Pulmonary stenosis in a dog submitted to valvuloplasty

Abstract

The Congenital heart diseases are characterized by morphological defects in the embryonic development and the most frequent in dogs are: pulmonary and aortic valve stenosis, ventricular septal defect and persistente ductus arteriosus.  They may occur asymptomatically or even evolve to congestive heart failure. The definitive diagnosis is made through the visualization of the alterations in the echocardiogram. In the present report, a French Bulldog, three month old, asymptomatic was presented to a private Veterinary practice in Rio de Janeiro, Brazil. Cardiac auscultation evidenced a systolic heart murmur in tricuspid focus and diastolic murmur in pulmonary focus. To better evaluate the dog  chest radiography, electrocardiogram and echocardiogram were perfomed and  allowed the diagnosis of pulmonary stenosis. The clinical treatment with beta-blocker was installed and the surgical procedure was performed with the ballon valvuloplasty. The aim of this study was to report a case of pulmonary artery stenosis in a puppy, treated clinically and surgically, emphasizing the importance of the physical and complementary cardiological exams.
