Abstract:

The Caspian miniature horse is one of the rarest small horse breeds in Iran. It is an Iranian breed with a small conformation compared to other breeds. In this study, the coronary arteries of six Caspian miniature horses older than two years were studied.

The origin, distribution and possible anastomoses of their branches were noticed. Three excised hearts were convoluted and injected with rodopas resin to obtain arterial casts. The other three hearts were injected with gelatin choromopaque and were subsequently radiographed.

The injected hearts and casts were carefully dissected and photographed. This study showed that the pattern of distribution of coronary arteries is almost similar to that of ordinary horses. No anastomoses were observed between branches of the left and right coronary arteries.

Key words: anatomy, horse, Caspian miniature horse, coronary artery.
