Q:how can multi valve prolapse affect me? (13 year old female)?
Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.
Q:reed valves on a 1999 yz 250?
reed valves depend on engine vacuum to operate. the reed valves are closed when the engine is off and as the engine load goes up, it requires more fuel so engine vacuum goes up causing the reed valves to open more, letting in more fuel. So, is the engine running or off?. are the reeds bent? if they are, they might be straightened if u use care. they break ez.
Q:Are valve stem seals the problem?

Q:Mitral valve repair surgery?
Very basically: The procedure is open heart and entails a complex system of sustaining life outside your body. The complications can vary. If you get a mechanical valve placed, your risk of embolus increases. Emboli can cause strokes and/or a fatal episode. However, once one recovers from either surgery (typically a short stint in the ICU but varying by the individual) the quality of life improves to better than pre-op. The need for a replacement may arise down the line. Barring any blood clots or infections, a MVP repair/replacement surgery does not by itself indicate anything about how long a patient survives post-op. A repair surgery tends to yield fewer long-term complications simply because no foreign tissue or synthetic material was introduced into one's system and the whole procedure is significantly lower risk in terms of infection. The risk of failure of a repaired valve is significantly lower than that of a replaced valve. Lots of variables influence the outcome though, and if this is a personal matter, I strongly suggest you speak candidly with your cardiologist. Bottom line: Repair surgery is generally safer and can allow the patient to live life fully.

Q:Aortic valve question?
This is a routine, well established procedure. The incidence of major complications are less than 4%. There are two kinds of artificial Heart Valves. One is mechanical, and the other is tissue valve. The mechanical valve requires the person to be on life long anti-coagulation therapy. This also requires periodic check on the persons pro thrombin time. Based on this, the anti-coaglation dose will be adjusted. The problem with anti-coagulation is that it may lead to bleeding complications. The tissue valve is made from the tissues of a bovine or porcine heart. The tissue is denatured to ensure that the valve is not rejected as a foreign tissue. (This is not a problem with mechanical valves.) Being made of tissue, these valves do not allow clots to form, which means that anti-coagulation after a short initial period is not required. This is a major advantage, especially for women, who may have some earlier bleeding problems. Then why are mechanical valves used at all? Being made from non-living denatured tissue, tissue valves cannot repair themselves. They also tend to get calcified in younger people with more calcium activity. They also have a shorter life than mechanical valves. Surgeons tend to favour mechanical valves for younger people (whose life expectancy is higher), and the tissue valve for the older, as such people may already have some bleeding problems, the valve's durability is not critical and the patient has lower calcium activity. These are general considerations. Only a surgeon armed with the full test results, and a knowledge of the patient history, who can advise the patient on what is the best option in each case. To reiterate, AVR (Aortic Valve Replacement, not my initials) is a routine procedure and recovery tends to be uneventful. Wish you all the best, and as uneventful a recovery as possible.
Q:97 Neon - Canister Purge Valve?
Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.
Q:Sound when I open or close rain bird sprinkler valve?
Provided you are talking about the valve that controls flow from the constant on of water to the sprinklers, that also cuts it off, the turning on is a groaning of the built up pressure (normal) releasing into the sprinkler line. The thump only occurs at the end when you close it because it's slowly cutting off the pressure. Its more pronounced in the sprinkler valves because you are dealing with greater pressure than say when you turn on a sink or hose, in fact you can nearly mimic a more muffled version of the sound by using a hose, and kinking it or using a nozzle head. Having installed 20+ of these working with my Dad on his rental properties, I can guarantee they are not silent. Unless water is spraying all over the place, I'm 98% positive its a perfectly functioning valve.
Q:Is there a difference between the two valves in each side of the heart?
Atrioventricular valves separate the atria and ventricles. Mitral valve has 2 flaps which separates the left atria and the left ventricle, whereas tricuspid valve has 3 flaps which separates the right atria and the right ventricle. I think there's only 1 pulmonary valve, which is located between the right ventricle and the pulmonary artery. Pulmonary valve and aortic valve, which lies between the left ventricle and the aorta, are two semilunar valves.
Q:Control Valve?
A major improvement in the DWEER system has been the development of the LinX (LinearExchanger) valve, which was patented byShumway . This valve replaced eight two-way valves with asingle multi-port spool valve which simplifiedthe system, improved reliability, reducedmaintenance requirements and allowed for fastervalve switching, reducing the size (and thus cost)of the energy recovery vessels. DWEER systemsutilize long vessels which may be installed underthe membrane vessels. Atpresent, the largest available DWEER system has a capacity of 500 m³/h.
