A technique for catheterisation of the coronary sinus in adult ponies (Equus caballus).
Long-term catheterisation of the coronary sinus using a specially designed catheter was accomplished in 6 ponies via a right lateral thoracotomy. The catheter comprised a 10 to 12 cm long stiff segment (Teflon) joined to a 100 cm length of pliable medical grade (vinyl) tubing. Catheters were kept functional up to 10 weeks postoperatively. Location of the catheter tip was verified by determining the oxygen tension of anaerobically withdrawn blood samples. Normal values of oxygen tension of the coronary sinus blood in ponies were similar to those reported for the dog, whereas oxygen content was significantly lower.
