Abstract: 

A general overview of tricuspid valve dysplasia in dogs is presented in this review. This congenitaldisease has been described in numerous large dog breeds but especially the Labradorretriever is predisposed. The condition is relatively uncommon, with a prevalence of approximatelyseven percent of all congenital heart diseases in dogs. The asymptomatic phase may lastfor several years and depends on the severity of the valve malformation. In the clinical phase,exercise intolerance, fatigue, anorexia, cardiac cachexia, dyspnea and signs of right-sided congestiveheart failure can be present. Echocardiography including Doppler imaging is warranted toconfirm the diagnosis. Curative treatment involves surgical valve replacement but is technicallychallenging and still in its experimental phase in dogs. As such, treatment in dogs involves theadministration of supportive medication once the dogs develop symptoms of congestive heartfailure and consists of diuretics, ace-inhibitors and positive inotropic drugs.
