Did you know a minimally invasive procedure can help some dogs born with pulmonic stenosis? ๐๐พ
Pulmonic stenosis is a congenital heart condition where the pulmonic valve is abnormally narrowed.
This narrowing partially obstructs blood flow leaving the heart, meaning the right side of the heart has to work much harder to pump blood. Over time, this can lead to exercise intolerance, weakness, collapsing episodes and, in some cases, heart failure.
A stent valvuloplasty is a minimally invasive procedure that can help relieve this obstruction. During the procedure, a balloon-tipped catheter is passed through a vein in the neck and guided to the narrowed valve. A stent (a small metal mesh tube) is then placed to help keep the narrowed area open. See the photo of a stent in place!
By widening the obstruction, blood can flow more easily from the heart, reducing strain on the right side of the heart and improving heart function and quality of life.
