Tricuspid Valve Dysplasia in Dogs
Tricuspid Valve Dysplasia is a medium-severity cardiac condition that can affect dogs of all ages and breeds. Tricuspid valve dysplasia is a congenital malformation of the right-sided tricuspid valve, causing regurgitation and right-sided heart enlargement. It can range from clinically insignificant to severe heart failure. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Birth-2 years. Early signs to watch for include heart murmur, abdominal distension (ascites), exercise intolerance, and jugular vein distension. When treatment is required, costs are estimated at £1,000-£3,500/year depending on severity, location, and the specific intervention needed. Tricuspid Valve Dysplasia has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
Signs & Symptoms
The following symptoms are commonly associated with Tricuspid Valve Dysplasia in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.
- Heart murmur
- Abdominal distension (ascites)
- Exercise intolerance
- Jugular vein distension
- Fainting

Diuretics, ACE inhibitors, and Pimobendan manage signs of congestive failure. Balloon valvuloplasty is not effective for dysplasia. Prognosis depends on severity.
Typical onset: Birth-2 years
Prevention & Screening
While not all cases of Tricuspid Valve Dysplasia can be prevented, the following steps reduce risk or enable earlier intervention:
- Cardiac clearance before breeding
- Avoid breeding affected dogs
Estimated Treatment Cost
Treatment for Tricuspid Valve Dysplasia is estimated at £1,000-£3,500/year, depending on severity, the specific intervention required, and your location.
