Definition of tricuspid in English:



  • 1Denoting a tooth with three cusps or points.

    • ‘The toothrow of Crotaphytus exhibits wide, robust teeth and consists of mostly tricuspid teeth that show little or no recurvature.’
    • ‘Some F 2 teeth are truly tricuspid, like those of LF, whereas others are truly bicuspid, as in MZ.’
    • ‘Next, we use field data for cichlid species with adult unicuspid, bicuspid, and tricuspid teeth.’
    • ‘Their tricuspid teeth (three sharp points per tooth) are especially adapted to feed on organisms with hard shells such as clams, snails, crabs and shrimp.’
  • 2Denoting or relating to a valve formed of three triangular segments, particularly that between the right atrium and ventricle of the heart.

    ‘tricuspid atresia’
    • ‘No involvement of the tricuspid valve was evident.’
    • ‘Ventricular contraction pushes up the tricuspid valve and raises pressure in the right atrium to a slight degree.’
    • ‘Producing a discrete line of ablation between the tricuspid annulus and the inferior vena cava gives a line of electrical block and is associated with a high success rate in terminating flutter.’
    • ‘A tricuspid regurgitant murmur may be heard, becoming more prominent as the right ventricle dilates.’
    • ‘The endocardial cushions form the lower atrial septum, the upper ventricular septum, the septal leaflet of the tricuspid valve and the anterior leaflet of the mitral valve.’
    • ‘These include conditions such as hypoplastic left heart syndrome and tricuspid atresia, in which the heart has only one functional pumping chamber instead of two.’
    • ‘Echocardiography is an important tool in the diagnosis of acute and massive pulmonary embolism, in which tricuspid valve regurgitation and an increase in right ventricular end-diastolic diameter and systolic pressure may be present.’
    • ‘In this particular case, the tricuspid papillary fibroelastoma was thought to be the cause of this patient's transient ischemic attack, manifesting as right arm and facial paresthesia and weakness.’
    • ‘A large mass was identified in the right atrium that extended through the tricuspid valve into the right ventricle almost to the right ventricular apex.’
    • ‘Moderate to severe tricuspid valve regurgitation was observed.’
    • ‘In the absence of cardiac failure, previous thromboemboli, or heart failure, antithrombotic therapy is not indicated in patients with isolated aortic or tricuspid valve disease.’
    • ‘The patient was admitted to the hospital, and an echocardiogram later demonstrated dilatation of the right ventricle and right atrium, moderate tricuspid regurgitation, together with evidence of moderate pulmonary hypertension.’
    • ‘All 6 of these patients presented with shortness of breath and clinical signs of congestive heart failure, and their autopsies showed right ventricle hypertrophy and tricuspid ring dilatation.’
    • ‘The mitral valve on the left side has two flaps, and the tricuspid valve on the right has three.’
    • ‘Deoxygenated blood from the venous circulation enters the right atrium from the inferior and superior vena cava and flows through the tricuspid valve into the right ventricle during ventricular diastole.’
    • ‘The peak velocity of the tricuspid regurgitant envelope was 4.0 m/s, suggesting a peak pulmonary artery systolic pressure of approximately 75 mm Hg.’
    • ‘He had a loud and a soft systolic murmur over the tricuspid area.’
    • ‘The addition of mean right atrial pressure to the peak tricuspid jet velocity gives an accurate noninvasive estimate of peak pulmonary pressure.’
    • ‘Deoxygenated blood first enters the right atrium of the heart and enters the right ventricle through the tricuspid valve.’
    • ‘If valvular disease occurs, it is most likely in the mitral, aortic, tricuspid, or pulmonary valve, in that order.’
    • ‘In older patients with Parkinson's disease, changes in the tricuspid valve may be most diagnostic, because the aortic and mitral valves may show age-related changes.’
    • ‘An incidental finding of lipomatous hypertrophy of the atrial septum and tricuspid annulus was reported.’
    • ‘The patient was a 70-year-old white woman with a history of rheumatic heart disease who presented in 1985 with mitral valve and tricuspid valve regurgitation.’
    • ‘Later the disease damages the mitral, aortic and tricuspid valves.’
    • ‘Contraction of the right and left atria forces blood past the right tricuspid and left bicuspid valves into the right and left ventricles, respectively.’


Late 17th century: from tri- ‘three’ + Latin cuspis, cuspid- ‘cusp’.
