Method of selective and non-selective angiocardiography for the horse
Insights
A new, safe angiocardiography technique for horses was developed. This method provides clear images of the equine heart and circulatory system, aiding in diagnosis.
Area of Science:
- Veterinary Medicine
- Cardiovascular Imaging
- Equine Cardiology
Background:
- Angiocardiography is crucial for diagnosing cardiovascular diseases in horses.
- Existing techniques may have limitations in safety or image quality.
- A need exists for a practical and reliable method for equine cardiac imaging.
Observation:
- A novel angiocardiography technique was developed for horses.
- The procedure involves rapid contrast agent injection into cardiac chambers and major vessels.
- Examinations were performed on standing or anesthetized horses.
Findings:
- Satisfactory angiocardiograms were obtained in 10 normal horses.
- Detailed images of ventricles, pulmonary arteries, aorta, and coronary circulation were achieved.
- The technique was successfully applied to a foal with congenital heart disease.
- Minimal adverse effects were noted, including infrequent ventricular premature contractions.
- No toxicity was observed with repeated contrast injections.
Implications:
- This technique offers a safe and effective method for equine cardiovascular assessment.
- It can aid in the diagnosis of various heart conditions in horses.
- The method provides valuable insights into equine cardiac and vascular anatomy and pathology.
Abstract:
A practical and safe method of angiocardiography for the horse is described. The technique involved the rapid injection of 50 to 150 ml contrast agent via catheters in the right and left heart, pulmonary artery and aorta. The examination was carried out with the horse in the standing position or under general anaesthesia. Angiocardiograms were performed on 10 normal horses and satisfactory pictures of the right and left ventricles, pulmonary arteries, aorta and coronary circulation were obtained. The technique was also used in a foal with severe congenital heart disease. The most practical methods of recording the images in the standing position were cinefilm or video taperecording. In the recumbent position both cinefilm and radiographs were taken. No damage to the heart was inflicted by the catheters and only a few ventricular premature contractions (less than five) were produced by the pressure of injection. No signs of toxicity were recorded using repeated injections of contrast material (ie, less than 600 ml).
