Plain-English summary

Five Arabian or half-Arabian foals were found to have serious heart problems that were suspected before they were examined. A variety of tests, including heart scans and X-rays, helped veterinarians identify the specific heart issues in these foals. Four of the foals were confirmed to have different heart defects after they passed away, including conditions like a serious heart vessel issue and a combination of other heart problems. One foal survived and was thought to have a hole between the heart chambers and another heart vessel issue. Overall, the treatment and diagnosis process was thorough, but unfortunately, most of the foals did not survive their heart conditions.

Abstract

Five Arabian or half-Arabian foals with suspected multiple cardiac anomalies were examined. Various combinations of clinical examination, electrocardiography, angiocardiography, cardiac catheterization, blood gas analysis, radiography, and echocardiography resulted in clinical data that allowed accurate antemortem diagnoses to be made. In 4 cases, the clinical diagnosis was substantiated by postmortem findings. The confirmed diagnoses were: pseudotruncus arteriosus, a combination of patent ductus arteriosus, pulmonic stenosis, and tricuspid stenosis, pentalogy of Fallot, and tricuspid atresia. The surviving horse was believed to have an interventricular septal defect and patent ductus arteriosus, or a persistent truncus arteriosus.
