Heart valve dysplasia is an error in the development of any of the heart valves, and a common cause of congenital heart defects in humans as well as animals; tetralogy of Fallot is a congenital heart defect with four abnormalities, one of which is stenosis of the pulmonary valve. Ebstein's anomaly is an abnormality of the tricuspid valve.1
Rheumatic fever was in the past a common cause of valvular heart disease (referred to as "rheumatic heart disease"). Inflammation of the heart valves due to any cause is called endocarditis; this is usually due to bacterial infection but may also be due to cancer (marantic endocarditis), certain autoimmune conditions (Libman-Sacks endocarditis) and hypereosinophilic syndrome (Loeffler endocarditis). Certain medications have been associated with valvular heart disease, most prominently ergotamine derivatives pergolide and cabergoline.2
Heart valve dysplasia
Heart valve dysplasia is a congenital heart defect which in dogs and cats affects the aortic, pulmonary, mitral, and tricuspid heart valves. Pulmonary valve stenosis and aortic valve stenosis are discussed separately. Dysplasia of the mitral and tricuspid valves can cause leakage of blood or stenosis.
Dysplasia of the mitral and tricuspid valves - also known as the atrioventricular (AV) valves - can appear as thickened, shortened, or notched valves. The chordae tendinae can be fused or thickened. The papillary muscles can be enlarged or atrophied. The cause is unknown, but genetics play a large role. Dogs and cats with tricuspid valve dysplasia often also have an open foramen ovale, an atrial septal defect, or inflammation of the right atrial epicardium.1 In dogs, tricuspid valve dysplasia can be similar to Ebstein's anomaly in humans.2
Mitral valve stenosis is one of the most common congenital heart defects in cats. In dogs, it is most commonly found in Great Danes, German Shepherd Dogs, Bull Terriers, Golden Retrievers, Newfoundlands, and Mastiffs. Tricuspid valve dysplasia is most common in the Old English Sheepdog, German Shepherd Dog, Weimaraner, Labrador Retriever, Great Pyrenees,1 and sometimes the Papillon.citation needed It is inherited in the Labrador Retriever.3
The disease and symptoms are similar to progression of acquired valve disease in older dogs. Valve leakage leads to heart enlargement, arrhythmias, and congestive heart failure. Heart valve dysplasia can be tolerated for years or progress to heart failure in the first year of life. Diagnosis is with an echocardiogram. There is a poor prognosis with significant heart enlargement.

Even when we try to eat well, we're disadvantaged. The nutritional content of most food has been compromised over the years, not only by deficient soils and modern production, transportation, storage and processing methods, but also by the enormous amounts of chemical and artificial substances added to promote growth, storage life, taste and appearance.
It's for this reason that more and more medical authorities are advocating the use of vitamin and mineral supplements. However, finding them in the right combination can be both confusing and costly.
The nutrition products I am going to recommend you make use of knowledge gained from the botanical world's 6,000 year history. They incorporated health building nutritional herbs with the best modern technology to help our bodies cleanse and detoxify so that the cells - the tiniest living units - can be as fully nourished as possible.
This allows the cells to grow, repair and to perform their functions with the best possible efficiency so that we feel and look better and are more able to prevent and fight disease. Once the body begins to clear itself of toxins it can more efficiently absorb nutrition.
Further reading through our articles on health issues will give you a body of information that will help you decide what options you have to deal with the underlying causes of your problem through giving your body the nutrition products that will assist you body to heal from the inside out.
