What is tricuspid valve dysplasia?
Tricuspid valve dysplasia is a type of heart valve dysplasia where the right atrioventricular (tricuspid) valve is deformed. The atrioventricular vavle in the heart is responsible for making blood flow from the atria to the ventricles. If the valve is deformed, it can cause blood to flow back into the right atrium or lead to tricuspid regurgitation. A narrowing of the valve can also be present in dogs suffering from this type of heart valve dysplasia. All these problems make the heart of the dog work less efficiently.
