Total anomalous pulmonary venous connection in a foal.
Abstract: An 8-day-old Arabian-Morgan cross colt underwent cardiac evaluation. The foal was tachycardic, tachypneic, exercise intolerant and had a loud right-sided heart murmur and cyanotic mucous membranes. Total anomalous pulmonary venous connection was diagnosed with echocardiography and confirmed at postmortem examination. Total anomalous pulmonary venous connection is a very rare congenital cardiac abnormality that has not been reported before in the horse.

This research article investigates the case of an 8-day-old Arabian-Morgan cross foal diagnosed with total anomalous pulmonary venous connection via echocardiography, a rare congenital heart abnormality not previously reported in horses.
Introduction
- The research article examines a unique case of an Arabian-Morgan cross foal that displayed alarming symptoms, such as rapid heart rate (tachycardia), rapid breathing (tachypnea), intolerance to exercise, pronounced right-sided heart murmur and blue-tinted mucous membranes, indicative of cyanosis or low oxygen saturation.
Diagnosis
- Echocardiography, a diagnostic method that uses ultrasound waves to produce images of the heart, was employed to diagnose the foal. This tool revealed that the foal was suffering from total anomalous pulmonary venous connection.
Total Anomalous Pulmonary Venous Connection
- Total anomalous pulmonary venous connection is a severe and rare heart defect that is typically congenital (present from birth). This condition is characterized by the incorrect connection of the four pulmonary veins. Instead of directly connecting to the left atrium of the heart as they should, these veins connect abnormally, either directly or indirectly, to the right atrium or systemic veins.
- This abnormal connection leads to oxygen-rich blood from the lungs being misdirected to the right side of the heart, leading to symptoms of cyanosis, tachycardia, tachypnea, and exercise intolerance as were observed in this foal.
Confirmation of Diagnosis
- The foal’s diagnosis was confirmed through a postmortem examination, which is an autopsy or a detailed examination of the body after death used to establish the exact cause of the death.
Significance
- The research article is significant as it reports the first known instance of total anomalous pulmonary venous connection in a horse. This discovery enhances the understanding of congenital heart defects in horses and highlights the importance of echocardiography in diagnosing these conditions.
