- Having three cusps or points: specifically noting the valvular arrangement in the right ventricle of the heart, guarding the auriculoventricular orifice, in distinction from the bicuspid (or mitral) valves in the left ventricle. This valve consists of three segments, or there are three valves, of a triangular or trapezoidal shape, each formed by a fold of the lining membrane of the heart, and strengthened by a layer of fibrous tissue which may also contain contractile fibers. See cut II. under heart.
- n. A tricuspid valve of the heart.

Examples
“The pulsation may be described as tricuspid; that is, it consists of a strong beat, preceded and followed by lesser beats.”
Hygienic Physiology : with Special Reference to the Use of Alcoholic Drinks and Narcotics
“The valve on the right side is called the tricuspid, because it consists of three little folds which fall over the opening and close it, being kept from falling too far by a number of slender threads called chordæ tendinæ.”
“The valve which guards the entrance into the right ventricle is called tricuspid, and consists of three flaps attached by delicate tendinous cords in such a way as to hinder the tending backwards of the flaps into the right auricle, and so allowing the blood to flow back into that chamber.”
“Children with tricuspid atresia always have an atrial septal defect, a hole between the right atrium and left atrium, so that oxygen-poor and oxygen-rich blood (blue and pink blood) mix inside of the heart.”
“Single ventricle defects include hypoplastic left heart syndrome, tricuspid atresia, double inlet left ventricle, some heterotaxy defects and others.”
“An abnormal valve that tends to leak (Doctors call this an “Ebstein-like” tricuspid valve.)”
Congenitally Corrected Transposition of the Great Arteries (CCTGA)
“In a normal heart, two valves separate the upper and lower chambers of the heart: the tricuspid valve separates the right chambers and the mitral valve the left.”
“Some babies with tricuspid atresia are too “pink” or have too much blood-flow to the lungs, and will require an operation called “pulmonary artery banding” to narrow the pulmonary artery and regulate blood flow to the lungs.”
“Not all babies with tricuspid atresia require prostaglandin.”
“Any of the above operations may also have to include replacement of the leaky tricuspid valve with an artificial valve, and insertion of a pacemaker.”
