1Having three cusps or points, in particular.
- ‘Dilatation of the tricuspid annulus resulting in tricuspid insufficiency occurs as the right ventricle fails.’
- ‘It showed acute right ventricular failure, marked right ventricular dilation, bulging of the interventricular septum from right to left, severe tricuspid regurgitation, and a small pericardial effusion.’
- ‘These researchers reported cardiac carcinoid involvement in the form of endocardial fibrosis leading to tricuspid insufficiency.’
- ‘Patients with evident extravascular fluid retention should be diuresed until the disappearance of excess fluid and the normalization of jugular venous pressure (unless tricuspid regurgitation is present).’
- ‘The study was technically limited due to the patient's size and large plasmacytoma in his chest but did show mild aortic stenosis and mild tricuspid and mitral regurgitation.’
- ‘The method used to measure pulmonary artery pressure required a regurgitant tricuspid jet; therefore, baseline pulmonary artery pressure measurements were available in only 35 subjects with OSA.’
- 1.1Denoting a tooth with three cusps or points.
- ‘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.’
- ‘The toothrow of Crotaphytus exhibits wide, robust teeth and consists of mostly tricuspid teeth that show little or no recurvature.’
- 1.2Denoting or relating to a valve formed of three triangular segments, particularly that between the right atrium and ventricle of the heart.
- ‘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 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 large mass was identified in the right atrium that extended through the tricuspid valve into the right ventricle almost to the right ventricular apex.’
- ‘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.’
- ‘Deoxygenated blood first enters the right atrium of the heart and enters the right ventricle through the tricuspid valve.’
Late 17th century: from tri- three + Latin cuspis, cuspid- cusp.
