The valve of the inferior vena cava (eustachian valve) serves to direct the blood into the right atrium.The Eustachian Valve (EV) also called «valvulae venae cavae inferioris» has been described for the first time by the Italian anatomist: Bartolomeo Eustachi (born between 1500 and 1513, died 1574 ).



The eustachian valve is the valve at the distal end of the inferior vena cava the passes blood from the lower extremities into the Right Atrium of the heart

Structures atria (interatrial septum, musculi pectinati) • ventricles (interventricular septum, trabeculae carneae, chordae tendinae, papillary muscle) • valves • cusps
Regions base • apex • grooves (coronary/atrioventricular, interatrial, anterior interventricula, posterior interventricular) • surfaces (sternocostal, diaphragmatic) • borders (right, left)
Right heart (vena cavae, coronary sinus) → right atrium (auricle, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of the inferior vena cava, valve of the coronary sinus) → tricuspid valve → right ventricle (conus arteriosus, moderator band/septomarginal trabecula)  → pulmonary valve → (pulmonary artery and pulmonary circulation)
Left heart (pulmonary veins) → left atrium (auricle) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)
