Insufficiency of the tricuspid valves is the incomplete closure of the inlet valve between the right atrium and the right ventricle during systole. The blood flows back into the right atrium.
One possible way of developing this disease is overstretching the retaining ring of the tricuspid valves. Another reason can also be excessive pressure in the right heart, which the valves cannot withstand.
The dachshund is particularly affected by the disease. Tricuspid valve regurgitation is often diagnosed purely by chance, as the disease can last for years without clinical symptoms. If symptoms do show up, these are: abnormal liver enlargement, ascites, weight loss, loss of appetite, vomiting and diarrhea.
If the insufficiency is still in its early stages, the prognosis is favorable with treatment and the dog can reach a normal age. If the disease is more advanced and has reached severe chronic tricuspid valve insufficiency, cirrhosis of the liver can occur due to the constant liver congestion.
Since around every tenth dog, and every fourth dog from the age of seven, suffers from a heart defect, it is advisable to go to the vet for an early diagnosis check. With this you can quickly find out whether your dog belongs to the risk group. With contaminated breeds, you should pay attention to a heart-healthy breed!
