Abstract
The paper presents statistical results of identifying combinations of various congenital heart defects in dogs of different breeds diagnosed with pulmonary artery valve stenosis. The study was retrospective, conducted on the basis of the Department of General, Private and Operative Surgery, as well as in the veterinary clinic of neurology, traumatology and intensive care. The total sample amounted to 100 animals. All animals underwent a complete physical examination. The morphofunctional state of the heart was evaluated. Diagnosis was made by echocardiography using Doppler. Each congenital heart defect was evaluated and studied separately, noting its individual features and hemodynamic changes in the combination of several congenital anomalies of heart development. The study was conducted before performing surgical treatment of pulmonary artery valve stenosis by balloon plasty of the pulmonary artery valve. This study included animals with other cardiac anomalies in addition to obstructive right ventricular outflow tract disease. Among 100 dogs examined, the most frequent combined heart defect was Fallot's tetrad. This pathology was singled out separately, as its mechanism of development differs significantly from a simple combination of several anomalies of heart development. It is believed that this is one heart defect consisting of several components. In addition, atrial septal defect, mitral or tricuspid valve dysplasia, open ductus arteriosus, and aortic valve stenosis were found in combination with pulmonary valve stenosis. Combined heart defects were most common in French Bulldog dogs in this study, as this is the most common breed of dog diagnosed with pulmonary valve stenosis.
