2. Tricuspid regurgitation - Wikipedia

   en.wikipedia.org/wiki/Tricuspid_regurgitation

   Tricuspid regurgitation. Tricuspid regurgitation ( TR ), also called tricuspid insufficiency, is a type of valvular heart disease in which the tricuspid valve of the heart, located between the right atrium and right ventricle, does not close completely when the right ventricle contracts ( systole ). TR allows the blood to flow backwards from ...

3. Valvular heart disease - Wikipedia

   en.wikipedia.org/wiki/Valvular_heart_disease

   Valvular heart disease is any cardiovascular disease process involving one or more of the four valves of the heart (the aortic and mitral valves on the left side of heart and the pulmonic and tricuspid valves on the right side of heart). These conditions occur largely as a consequence of aging, [ 1] but may also be the result of congenital ...

4. Tricuspid valve - Wikipedia

   en.wikipedia.org/wiki/Tricuspid_valve

   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 ...

5. Tricuspid valve stenosis - Wikipedia

   en.wikipedia.org/wiki/Tricuspid_valve_stenosis

   Tricuspid valve stenosis. Tricuspid valve stenosis is a valvular heart disease that narrows the opening of the heart's tricuspid valve. It is a relatively rare condition that causes stenosis (increased restriction of blood flow through the valve). [ 1]

6. Heart valve - Wikipedia

   en.wikipedia.org/wiki/Heart_valve

   A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. Four valves are usually present in a mammalian heart and together they determine the pathway of blood flow through the heart. A heart valve opens or closes according to differential blood pressure on each side. [1] [2] [3]

7. Ebstein's anomaly - Wikipedia

   en.wikipedia.org/wiki/Ebstein's_anomaly

   Specialty. Cardiology. Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [ 1] EA has great anatomical heterogeneity that generates a wide spectrum of clinical features at presentation and is complicated by ...

8. Mitral valve prolapse - Wikipedia

   en.wikipedia.org/wiki/Mitral_valve_prolapse

   Mitral valve prolapse (MVP) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. [4] It is the primary form of myxomatous degeneration of the valve. There are various types of MVP, broadly classified as classic and nonclassic.

9. Bicuspid aortic valve - Wikipedia

   en.wikipedia.org/wiki/Bicuspid_aortic_valve

   Specialty. Cardiology. Bicuspid aortic valve ( BAV) is a form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet (bicuspid) valve instead of the normal three-leaflet (tricuspid) valve. BAV is the most common cause of heart disease present at birth and affects ...
