Mild tricuspid regurgitation tends to be common and, in the presence of a structurally normal tricuspid valve apparatus, can be considered a normal variant. [21] Clinically significant TR is more common in females, this is thought to be partly driven by the increased prevalence of atrial fibrillation and heart failure with preserved ejection ...
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
Ebstein's anomaly is an abnormality of the tricuspid valve, and its presence can lead to tricuspid valve regurgitation. [16] [18] A bicuspid aortic valve [16] is an aortic valve with only 2 cusps as opposed to the normal 3. It is present in about 0.5% to 2% of the general population and causes increased calcification due to higher turbulent ...
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.
Heart valve dysplasia (including mitral and tricuspid valve dysplasia) is a congenital heart abnormality in dogs. Dysplasia of the mitral and tricuspid valves - also known as the atrioventricular (AV) valves - can appear as thickened, shortened, or notched valves. Chordae tendineae are also usually abnormal.

Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve. The mitral valve may need to be replaced because: [1] The valve is leaky (mitral valve regurgitation) The valve is narrowed and doesn't open properly (mitral valve stenosis)
Mitral regurgitation, also known as mitral insufficiency or mitral incompetence, is the backward flow of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, resulting in a systolic murmur radiating to the left armpit.
A valve prolapse can result in mitral insufficiency, which is the regurgitation or backflow of blood from the left ventricle to the left atrium due to the incomplete closure of the valve causing a systolic murmur heard at the apex of the heart. This increase in pressure in the left atrium and pulmonary circuit can lead to symptoms like fatigue ...
