A retrospective study of tetralogy of Fallot in dogs

Objective & Hypothesis:Tetralogy of Fallot is a rare congenital heart defect; however, it is the most common cyanotic heart malformation in humans and animals.

📊

Key Findings & Data:At the Department of Internal Medicine Clinic of Diseases of Horses, Dogs, and Cats at the Wroclaw University of Environmental and Life Sciences, patients with Fallot syndrome constituted 4.44% of all patients with congenital heart diseases.

💡

Conclusion & Impact:Surgery is the only effective method of treatment; however, for animals, we only provide palliative treatment.

🔬Design:Research Article

📍Scope:Comprehensive Sample

⚙️Variables:Key words: Tetralogy of Fallot · cyanosis · congenital heart disease

Abstract

Tetralogy of Fallot is a rare congenital heart defect; however, it is the most common cyanotic heart malformation in humans and animals. It consists of a ventricular septal defect, pulmonic stenosis, displacement of the aortic root, and hypertrophy of the right ventricle. At the Department of Internal Medicine Clinic of Diseases of Horses, Dogs, and Cats at the Wroclaw University of Environmental and Life Sciences, patients with Fallot syndrome constituted 4.44% of all patients with congenital heart diseases. There was no breed predisposition found. The most common clinical signs were exercise intolerance, dyspnea, and cyanosis of the mucous membranes, but it can also be asymptomatic. Echocardiography is considered to be the best method for diagnosing this congenital heart disease. Contrast angiocardiography can be used to confirm the diagnosis or as a complement to diagnosis. Surgery is the only effective method of treatment; however, for animals, we only provide palliative treatment.
