Proposed Laser Ventriculocordectomy for Roarer

Hello mokuc,
No I do not have personal experience with laser for laryngoplasty but I have opinions about your post. First I agree with the assessment that laying down a 25 year old horse should be avoided. Second I think a 30% increase in cross dimensional area would significantly increase the amount of air flow through the larynx at a given pressure gradient. How sure is your veterinarian is that this is the cause of the exercise intolerance. It certainly is sensible but chronic lung disorders are so common in the horse, think different forms of asthma, that I would want to do all I could to rule these out before the surgery. In the end you do the surgery and then see if you can get a horse that can tolerate light exercise. Most can if your expectations are not to high.
