The tricuspid valves are placed, like gate-keepers, at the entrance into the ventricles from the venae cavae and pulmonary veins, lest the blood when most forcibly impelled should flow back.
Emboli from the veins of the body are carried through the right side of the heart, if not so large as to be stopped at the tricuspid or pulmonary opening.
Pulsation of the jugular veins is ordinarily explained by tricuspid regurgitation, a portion of the blood being sent back to the vena cava with an impulse reaching to the jugulars.
These novel statements are confirmed by the observations of Parrot, Balfour, and William Russell,[71] which go to prove that tricuspid regurgitation occurs frequently in the more advanced stages of debility.
The growing opinion, however, respecting so-called anaemic murmurs is, that they depend chiefly upon regurgitation through the tricuspid orifice, although Dr.
It remains to speak briefly of temporary incompetence of the mitral and tricuspid valves and their dynamic murmurs, and of haemic murmurs.
The former consist of pericarditis, endocarditis, and myocarditis; the latter embrace deposition of fibrin on the valves, temporary incompetence of the mitral or tricuspid valves, and the formation of thrombi in the cavities of the heart.
Having three cusps, or points; tricuspidate; as, a tricuspid molar.
Defn: Of or pertaining to the tricuspid valves; as, tricuspid obstruction.
The tricuspid valve (three segments) closes the opening between the right auricle and right ventricle.
There was a circular lacerated opening in the tricuspid valve, and the ball must have been in the right auricle during the fourteen days in which the man lived.
The tricuspid valves had lost their smoothness and transparency; the semilunar valves of the pulmonary artery were cartilaginous at their bases.
The tricuspid valves and the semilunar valves of the pulmonary artery had lost their healthy transparency, but were not otherwise diseased.
The tricuspid valves, and the valves of the pulmonary artery, had lost somewhat of their transparency, and were a little thickened, though not materially.
The dark blood from the veins collects in the right auricle, and, going through the tricuspid valve, empties into the right ventricle.
The first sound is caused mainly by the tricuspid and mitral valves, and the second is the result of sudden closure of the semilunar valves.
Attached to these fibrous rings are the movable partitions or valves, between the auricles and the ventricles, the one on the right side of the heart being called the tricuspid valve, and the one on the left side the mitral valve.
The tricuspid and mitral valves were thickened, and exhibiting minute granulations on their surface.
They are herbivorous fishes, with flat, tricuspid teeth, and except for their pectoral fins are very similar to the Kyphosidæ.
The hard-head (Chriodorus atherinoides) has no beak at all and its tricuspid incisor teeth are fitted to feed on plants.
When viewed from the right side of the heart, the bundle can not be seen, because it is covered by the mesial leaflet of the tricuspid valve, whose line of attachment passes obliquely over the membranous septum.
If a lesion at the base of the mesial segment of the tricuspid valve damages His' bundle, so that Tawara's node is cut off from the ventricle, then the ventricle may originate its own impulses to contraction.
It is due to the dilatation of its walls, to the displacement of the auriculoventricular septum toward the apex occurring at the time of ventricular systole, and to the pull of the papillary muscles on the tricuspid valve leaflets.
Hirschfelder has described another wave which he calls the "h" wave, which is due to the floating up of the tricuspid valve by the blood in the ventricle before the complete filling of the ventricle following the auricular systole.
Tricuspid stenosis, pulmonary stenosis and pulmonary insufficiency are rare, and are probably nearly always congenital.
A special treatment of the heart, if any is needed, would probably not be indicated unless there was associated tricuspid insufficiency, when digitalis might be used.
Moreover, the contraction of the right heart may cause a wave in the veins of the extremities, and he believes that incompetency of the tricuspid valve may be the cause of varicosities in the veins of the extremities.
Not infrequently soft systolic murmurs are heard at the pulmonary and tricuspid valves during acute endocarditis.
The heart is found enlarged, the apex beat diffuse and there may be a systolic blow at the mitral or tricuspid valve.
The tricuspid valves (17) prevent the reflow of the blood from the right ventricle to the right auricle.
The tricuspidin the same way allows, normally, three fingers to pass; or if a more accurate test of the degree of insufficiency is desired, the valvular orifices should be measured.
The mitral and tricuspid valves are formed by the shortening of the auricular canal which becomes telescoped into the ventricle, and the cusps are the remnants of this telescoping process.
In fact, this compartment receives all the venous or impure blood from all parts of the body, and sends it through what is known as the tricuspid valve into the right ventricle or lower compartment.
Tricuspid stenosis is an obstruction of the tricuspid opening, usually congenital, though it may be acquired.
This condition is an imperfect closure of the tricuspid valves, due to dilation of the right ventricle or to disease of the valves.
The valve on the left side, called the mitral, from its fancied resemblance to a bishop's mitre, consists of two folds which close together as do those of the tricuspid valve.
Gradually enlarge the opening until the chordæ tendineæ and the flaps of the tricuspid valve are seen.
The tricuspid valve at once closes, and blocks the way backward.
The context shows that the phrase "from without inward" indicates the true insertion of the "membranes" of the tricuspid valve, according to both Galen and the facts.
Thus does the great English discoverer bring the pulmonary transit and the circulation of the blood to the rescue of the Aristotelian heart, despite Galen and the tricuspid valve!
That the heart throughout life is not only the source of the perfected blood, but gives out blood to the vena cava for distribution, had been rendered a hard saying, especially by the recognition of the tricuspid valve.
It is exactly similar in structure and arrangement to the tricuspid valve, except that it is stronger and is composed of two parts instead of three.
The tricuspid valve and the chordæ tendineæ shown in the ventricle.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "tricuspid" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: deltoid; triangular; trident; tripartite
