    • ‘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.’
  • 2Denoting or relating to a valve formed of three triangular segments, particularly that between the right atrium and ventricle of the heart.

    ‘tricuspid atresia’
    • ‘Contraction of the right and left atria forces blood past the right tricuspid and left bicuspid valves into the right and left ventricles, respectively.’
    • ‘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.’
    • ‘Ventricular contraction pushes up the tricuspid valve and raises pressure in the right atrium to a slight degree.’
    • ‘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.’
    • ‘The mitral valve on the left side has two flaps, and the tricuspid valve on the right has three.’
    • ‘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.’
    • ‘If valvular disease occurs, it is most likely in the mitral, aortic, tricuspid, or pulmonary valve, in that order.’
    • ‘Later the disease damages the mitral, aortic and tricuspid valves.’
    • ‘No involvement of the tricuspid valve was evident.’
    • ‘Moderate to severe tricuspid valve regurgitation was observed.’
    • ‘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.’
    • ‘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.’
    • ‘An incidental finding of lipomatous hypertrophy of the atrial septum and tricuspid annulus was reported.’
    • ‘The addition of mean right atrial pressure to the peak tricuspid jet velocity gives an accurate noninvasive estimate of peak pulmonary pressure.’

    • ‘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.’
    • ‘He had a loud and a soft systolic murmur over the tricuspid area.’
    • ‘A tricuspid regurgitant murmur may be heard, becoming more prominent as the right ventricle dilates.’
    • ‘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.’


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