Tricuspid Valve Anatomy

In normal heart the tricuspid valve is located slightly closer to the apex than the mitral valve. It opens during diastole and closes during systole.

Percutaneous Treatment Of The Tricuspid Valve Disease New

It opens during ventricular diastole allowing blood to flow from the right atrium into the right ventricle.

Tricuspid valve anatomy. The tricuspid valve complex consists of the annulus leaflets right ventricle papillary muscles and chordae tendinae. The tricuspid valve tv is a complex structure. Right atrioventricular valve tricuspid valve these are large veins that transport deoxygenated blood from the body back to the heart.

It is the atrioventricular valve that allows blood to flow from the right atrium to the right ventricle. The red dotted lines show the direction of dilation of various structures in the setting of secondary tricuspid regurgitation. Unlike the aortic and mitral valve it is not possible to visualize all tv leaflets simultaneously in one cross sectional view by standard two dimensional echocardiography 2de either transthoracic or transesophageal due to the position of tv in the far field.

A the anatomy of the tricuspid valve and adjacent structures from a surgical view. The space in between the septal insertion of the tricuspid valve and the septal insertion of the anterior leaflet of mitral valve belongs to the membranous septum that separates the left ventricle from the right atrium. Anatomy of the tricuspid valve.

The tricuspid valve lies within the right trigone. The tricuspid valve has an area of 4 to 6 cm square and is located between the right atrium and the right ventricle of the heart. A greater appreciation of normal and abnormal anatomy is important as new methods of treating the tricuspid regurgitation are developed.

An appreciation of the complex and variable anatomy of the tricuspid valve is essential to unraveling the pathophysiology of tricuspid regurgitation. The tricuspid valve functions as a one way valve that closes during ventricular systole to prevent regurgitation of blood from the right ventricle back into the right atrium. The valve has anterior posterior and septal leaflets cusps the bases of which attached around the av orifice to the fibrous ring fibrous skeleton of the heart.

Anatomy of the tricuspid valve. The tricuspid valve lies between the right atrium and the right ventricle and is placed in a more apical position than the mitral valve. The tricuspid valve consists of three flaps or leaflets however cases are found when the tricuspid valve consists of only two or even four leaflets instead of the traditional three.

The tricuspid valve anatomy shows greater variability than the anatomy of the mitral valve. B the relevant anatomy shown from the front view. Then blood exits the heart via the pulmonary artery.

Blood collects within the right atrium and it must flow through the tricuspid valve in order to enter the right ventricle.
