The meaning of HEART VALVE is any of the valves that control blood flow to and from the heart and that include the atrioventricular valves, the aortic valve, and the pulmonary valve —called also cardiac valve.
semilunar valve- a heart valve with cusps shaped like half-moons; prevents blood from flowing back into the heart valve- a structure in a hollow organ (like the heart) with a flap to insure one-way flow of fluid through it 2.heart valve- an implant that replaces a natural cardiac valve...
: a bodily structure (as in a vein or the heart) that closes temporarily to prevent passage of material or that allows movement of a fluid in one direction only 2 a : a mechanical device by which the flow of liquid, gas, or loose material in bulk may be controlled by a movable ...
The purpose of our study was to determine whether CT can accurately evaluate mechanical heart valve size and function.Sixty-two patients with mechanical valves (37 single-disc, 27 bileaflet; 59 aortic, 5 mitral) were evaluated with ECG-gated 64-MDCT and transthoracic echocardiography; a subset of...
Key Structure–Function Correlations in the Cardiac Valves Heart valves are structural specializations of the cardiac tissues that ensure unidirectional blood flow through the heart; they open and close approximately 40 million times a year and three billion times over an average lifetime. Normal valve...

There has been increasing concern in recent years about the quality and cost of heart valvular replacement procedures. The purpose of this study is to examine the profile of patients undergoing valvular operations during the past decade, and to look at trends in outcome and resource utilization ...
They work in tandem with the atrioventricular valves, which are located between the atrium and the ventricle. Closure of the heart valves is associated with the audible heartbeat. The first sound occurs when the atrioventricular valves close, the second when the pulmonary and aortic semilunar ...
Heart valve disease: investigation by cardiovascular magnetic resonance Cardiovascular magnetic resonance (CMR) has become a valuable investigative tool in many areas of cardiac medicine. Its value in heart valve disease is les... Saul,G,Myerson - 《Journal of Cardiovascular Magnetic Resonance》 被引...
