After doing some research, I found a specialist that deals with pulmonic stenosis - Texas A&M. It's about 8.5 hours from us, but it's closer than TN! I had my vet consult and review the information I got from the group in KC. Basically, they said that there is no way they could give such a finite diagnosis as they did not run the correct tests. I have an appointment with them on Oct 8th. I had also contacted the specialist at UT I saw for my other bulldog - he forwarded the info to a cardiologist there... this is what the cardiologist said...
The workup is not complete, in my opinion. Despite the images being reviewed by a cardiologist, there is no severity of the pulmonic stenosis documented. This leaves open to question whether the right sided congestive heart failure is more due to the pulmonic stenosis or more due to the tricuspic regurgitation they commented on. With pulmonic stenosis, it would be more difficult to rule out pulmonary hypertension, but possible with a little mathematical gymnastics if they got a velocity on the tricuspid regurgitation (not documented).
The comment that bulldogs cannot undergo valvuloplasty for pulmonic stenosis is premature without an agiogram to confirm an aberrant coronary artery. Some bulldogs don't have coronary artery anomalies and can therefore be ballooned like any other dog.
In reality, since the dog is in right sided congestive heart failureit's late in the game. An angiogram might prove an aberrant right coronary artery, making valvuloplasty contrainidcated. but even if you could try valvuloplasty, it might not prolong life for very long at this stage of the game, especially if the tricuspid regurgitation is severe.
Bottom line: Winston should have seen a real cardiologist.
If anyone is close to UT, I highly recommend them. They have helped me so much with consults from a distance. I wish myself and Winston was well enough to make the trip, but unfortunately, we cannot, so Texas A&M will have to do. I'm hopeful though. While there may not be a surgery to "correct" his issues or fix him, I want to make sure he has the best care.
