Definition of tricuspid in English:



  • 1Denoting a tooth with three cusps or points.

    • ‘Next, we use field data for cichlid species with adult unicuspid, bicuspid, and tricuspid teeth.’
    • ‘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.’
    • ‘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.

    • ‘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.’
    • ‘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.’
    • ‘Deoxygenated blood first enters the right atrium of the heart and enters the right ventricle through the tricuspid valve.’
    • ‘Later the disease damages the mitral, aortic and tricuspid valves.’
    • ‘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.’
    • ‘No involvement of the tricuspid valve was evident.’
    • ‘Contraction of the right and left atria forces blood past the right tricuspid and left bicuspid valves into the right and left ventricles, respectively.’
    • ‘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.’
    • ‘The mitral valve on the left side has two flaps, and the tricuspid valve on the right has three.’
    • ‘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.’
    • ‘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.’
    • ‘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 addition of mean right atrial pressure to the peak tricuspid jet velocity gives an accurate noninvasive estimate of peak pulmonary pressure.’
    • ‘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.’
    • ‘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.’
    • ‘Moderate to severe tricuspid valve regurgitation was observed.’
    • ‘If valvular disease occurs, it is most likely in the mitral, aortic, tricuspid, or pulmonary valve, in that order.’
    • ‘Ventricular contraction pushes up the tricuspid valve and raises pressure in the right atrium to a slight degree.’
    • ‘He had a loud and a soft systolic murmur over the tricuspid area.’
    • ‘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.’
    • ‘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.’
    • ‘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.’
    • ‘A tricuspid regurgitant murmur may be heard, becoming more prominent as the right ventricle dilates.’
    • ‘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.’


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