Plain-English summary
A four-day-old male Arabian foal was diagnosed with a serious heart condition called pulmonary atresia, which means that the blood vessel that should lead to the lungs is blocked. This foal also had a poorly developed right ventricle (the heart chamber that pumps blood to the lungs) and a small tricuspid valve, which is the valve that controls blood flow from the right atrium to the right ventricle. The foal showed signs of cyanotic heart disease, which can cause a bluish tint to the skin due to low oxygen levels, and it appeared that blood was flowing incorrectly through the heart. An ultrasound of the heart showed these issues and signs of heart failure on the right side. This case is particularly notable because such a combination of heart defects is the first of its kind reported in this breed.
Abstract
Pulmonary atresia with intact ventricular septum, rudimentary tricuspid valve, hypoplastic right ventricle, and right-to-left atrial shunting were identified in a four-day-old, male Arabian foal with clinical signs of cyanotic heart disease. Pulmonary blood flow was apparently derived from a ductus arteriosus. Echocardiographic evaluation revealed the majority of cardiac abnormalities and also findings compatible with right-sided congestive heart failure. Congenital cardiac defects have a high incidence in this breed, and this is the first description of this combination of congenital cardiac defects.
