What's the difference between multivalve and valve?
Multivalve
Definition:
(n.) Any mollusk which has a shell composed of more than two pieces.
(a.) Alt. of Multivalvular
Example Sentences:

(6) The operative mortality rate was 8.3% in 661 patients having isolated aortic valve disease and 7.5% in 239 patients having isolated mitral valve disease, but 12.5% in 64 patients with multivalve disease undergoing single valve replacement.
(7) Subsequent research revealed that exclusion of air from the multivalve claw (hydraulic milking) produced the expected flooding of the liners and a milking action that was gentler to the teats and gave advantages in terms of milking performance, reduced lipolysis and milk sensing.
Valve
Definition:
(n.) A door; especially, one of a pair of folding doors, or one of the leaves of such a door.
(n.) A lid, plug, or cover, applied to an aperture so that by its movement, as by swinging, lifting and falling, sliding, turning, or the like, it will open or close the aperture to permit or prevent passage, as of a fluid.
(n.) One or more membranous partitions, flaps, or folds, which permit the passage of the contents of a vessel or cavity in one direction, but stop or retard the flow in the opposite direction; as, the ileocolic, mitral, and semilunar valves.
(n.) One of the pieces into which a capsule naturally separates when it bursts.
(n.) One of the two similar portions of the shell of a diatom.
(n.) A small portion of certain anthers, which opens like a trapdoor to allow the pollen to escape, as in the barberry.
(n.) One of the pieces or divisions of bivalve or multivalve shells.
Example Sentences:
(1) This paper discusses the typical echocardiographic patterns of a variety of important conditions concerning the mitral valve, the left ventricle, the interatrial and interventricular septum as well as the influence of respiration on the performance of echocardiograms.
(2) External phonocardiography performed at the time of cardiac catheterization revealed that this loud midsystolic click disappeared whenever a catheter was positioned across the mitral valve.
(3) All patients with localized subaortic hypertrophy had left ventricular hypertrophy (left ventricular mass or posterior wall thickness greater than 2 SD from normal) with a normal size cavity due to aortic valve disease (2 patients were also hypertensive).
(4) Valve-related complications were noted in four patients.
(5) Digestion is initiated in the gastric region by secretion of acid and pepsin; however, diversity of digestive enzymes is highest in the post-gastric alimentary canal with the greatest proteolytic activity in the spiral valve.
(6) The aortic area (Torlin) for diseased stenotic aortic valves was calculated in 10 patients using two different methods; data obtained in preoperative cardiac catheterization and by intraoperative flowmetric and aortic and left ventricular pressure-recording measurements, and their mutual correlation was tested.
(7) He underwent a mitral and aortic valve replacement, followed by a complicated postoperative course.
(8) In addition, spontaneous platelet aggregation is increased when vegetations are present on cardiac valves.
(9) This report represents the first comprehensive description of instantaneous and continous phasic blood velocity at the mitral valve during atrial arrhythmias in man.
(10) This study demonstrated that significant global and regional ventricular dysfunction develops immediately after removal of the papillary muscles, whereas myocardial contractility is preserved in patients undergoing mitral valve repair.
(11) The autopsy findings in 41 patients with University of Cape Town aortic valve prostheses were studied.
(12) This developed concept of "valve only" energy loss has the potential of standardising the findings of different research groups by removing the arbitrary selection of measurement points from reported results.
(13) The organisms were predominantly associated with host deposits of erythrocytes, phagocytes, platelets, and fibrinous-appearing material, which collectively appeared on the valve surface in response to trauma.
(14) Autopsy revealed a primary intimal sarcoma with osteogenic elements arising in the posterior leaflet of the pulmonary valve and obstructing the main pulmonary artery and its right branch.
(15) With a series of 117 aortic valve replacements, the authors have examined the results in relation to the method of protecting the myocardium while the aorta is clamped off.
(16) Left ventricular rupture is a serious complication of mitral valve replacement.
(17) Any type of valve element can serve as the expiratory valve.
(18) Echocardiographic findings included an abrupt midsystolic, posterior motion (greater than 3 mm beyond the CD line) in five patients, multiple sequence echoes in six, and posterior coaptation of the mitral valve near the left atrial wall in six.
(19) A block of tissue bounded by the ostium of the coronary sinus, the pars membranacea, the septal leaflet of the tricuspid valve and the atrial and ventricular septa is removed.
(20) A case of tricuspid valve endocarditis with spinal epidural abscess caused by Actinobacillus actinomycetemcomitans is reported in a 74-year-old male with an endocardial pacemaker.
