- Q: what does mild sclerosis of aortic valve means? Why does it happens and what is its curethanks
- Sclerosis means hardening. Aortic sclerosis, a degenerative aortic valve disease with thickening of aortic valve structures by fibrosis and calcification initially without causing significant obstruction, is the most common cause of AS in elderly patients. Over years, aortic sclerosis progresses to stenosis in as many as 15% of patients. Aortic sclerosis resembles atherosclerosis, with deposition of lipoproteins, active inflammation, and calcification of the valves; risk factors are similar. Aortic stenosis is the narrowing or obstruction of the heart's aortic valve, which prevents it from opening properly and blocks the flow of blood from the left lower chamber of the heart to the aorta. The aorta is the main artery leaving the heart. Aortic insufficiency is a heart valve disease in which the aortic valve weakens or balloons, preventing the valve from closing tightly. This leads to backward flow of blood from the aorta (the largest blood vessel) into the left ventricle (the left lower chamber of the heart). Causes of increased afterload that can cause LVH include aortic stenosis, aortic insufficiency, and hypertension. Primary disease of the muscle of the heart that cause LVH are known as hypertrophic cardiomyopathies, which can lead into heart failure.
- Q: Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
- Firstly both conditions are not necessarily serious. Prolapse is the phenomenon of one or both mitral leafets bending slightly into the left atrium when the heart contracts. Normally when the leaflets close they dont clise straight but form a slight tent shape facing towards the LV. With prolapse the leaflet bends beyond the imaginary straight line of the valve annulus. Regurgitation is simply back flow through a valve when closed - all valves function as one way check valves to ensure one way flow through the heart. Its completely normal to have a small amouny of regurgitation at all valves except the aortic valve. Mitral regurgitation typically worsens with prolapse because the valve isnt closing properly. Usually prolapse and mitral regurgitation are not all that serious and only require periodic monitoring. Consult your DR if you suddenly develoop symptoms like chest pain or breathlessness. These can indicate the valve is degenerating further and may require medical treatment.
- Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
- its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .
- Q: We have a 2005 GMC Sierra 1/2 ton truck that has a check engine light on. The dealer checked the code and he told us we need a new Evap Vent Valve and clamp. The cost is over 500.00 with labor being most of the cost. Is this diffcult to change out? Im a very mechanical person. Also he said it would be ok to drive for now but could cause problems down the road. ????like what?My wife is getting ready to take a trip in it, should it be ok for awhile? Dont have 500+ to spend on it now.
- How Does Evap System Work
- Q: Can sum1 tell me how i can tell if my valves are in the right place?I notice there are holes in the valves, please explain how those holes are suppose to face to for each of the 3 valves?
- Put the correct valve in the valve case. (There is usually a notch that guides the placement, but it is not always accurate enough.) Blow gently into the trumpet, (you don't need to play, just blow as you do to clear the spit valves). If you feel a resistance, rotate the valve until the resistance is gone. When there is no resistance with the valve up, depress the valve and blow again. There should be no resistance there either. Repeat with each valve.
- Q: I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!
- first of all, lemme be frank to say that your question is not clear to me. however, i wud like to give my answer below with my understanding of your question. generally, the term pneumatic valve means that the actuating force to operate the valve itself is pneumatic(driven by air pressure) and not the service fluid (i.e. the fluid which passes through the valve). with the above understanding, industrial standard pneumatic pressure could be 3 - 15 psi (or) 0.2 to 1 kg/cm2. on the other hand, if your question means that you want to know about the electrical driven valves, then the industrial standard is 115VAC Solenoid valves (or) 24VDC Solenoid Valves. There could be other ratings as well.
- Q: When i was 14 I was diagnosed with a moderate aortic bicusspid valve. I am now 19 at my first cardiologist appointment I was still at moderate. Three months later when i went back in I was rediagnosed with a severe aortic valve. I have every symptom, and I'm getting ready to have it repalced. My question is what am I to expect after surgery. Will i be able to work if not is there anything I can do to have some sort of an income comming in?
- confident you could have continually had this, that's some thing you have been born with. a classic aortic valve is tricuspid, it is it has 3 last flaps, yet a bicuspid valve purely has 2 flaps. sometimes those bicuspid valves provide no issues, yet in some human beings they could bring about coronary heart murmur later in existence ( oftentimes on your 30s or 40s ) simply by fact they permit a sprint blood to leak returned the incorrect way while they are closed. If this gets intense sufficient, you would be able to choose surgical treatment to greater healthful a synthetic valve. that's enormously ordinary those days and not some thing to rigidity approximately.
- Q: give some application of varible throttle valve?
- A throttle valve allows continuous control of the rate at which some fluid moves from a region of relatively high pressure into a region of relatively low pressure. An example would be in an automobile engine, where the throttle controls the rate at which air (at or above atmospheric pressure) enters the engine's intake manifold (near vacuum when the throttle is closed.) The throttle in an automobile engine is mechanically linked to the gas pedal (in case you didn't know).
- Q: My Dr placed me in the care of a cardiologist who ran some test and an echo scan reports i have a leaking valve but she failed to tell me which one and i failed to even think to ask. What are the results of leaking heart valves? I asked my mother and she says each one has a different result. What are they? Any help would be great. thanks.
- How the Heart Valves Work At the start of each heartbeat, blood returning from the body and the lungs fills the atria (the heart's two upper chambers). The mitral and tricuspid valves are located at the bottom of these chambers. As the blood builds up in the atria, these valves open to allow blood to flow into the ventricles (the heart's two lower chambers). After a brief delay, as the ventricles begin to contract, the mitral and tricuspid valves shut tightly. This stops blood from flowing backward into the atria. As the ventricles contract, they pump blood through the pulmonary and aortic valves. The pulmonary valve opens to allow blood to flow from the right ventricle into the pulmonary artery. This artery carries blood to the lungs to get oxygen. At the same time, the aortic valve opens to allow blood to flow from the left ventricle into the aorta. The aorta carries oxygen-rich blood to the body. As the contraction ends, the pulmonary and aortic valves shut tightly. This stops blood from flowing backward into the ventricles. www.nhlbi.nih /health/dci/Dise...
- Q: Could I get some possible remedies for Mitral Valve Prolapse pain? I currently am off beta blockers, and I need to cope with the mild, moderate to severe chest pain I experience. Female, average weight for my height, nonsmoker, maybe one alcoholic drink a week, exercise at least 3.5 hours a week. What do others with mitral valve prolapse do that helps?
- Beta blockers are effective in reducing the chest pain related to the mitral valve prolapse syndrome and there are some other lifestyle modification that you can do to help improve your symptoms. It is important though that you be evaluated by your doctor (which I am sure you have) to determine if this chest pain is truly related to the mitral valve prolapse and not some other cause of chest pain. Other causes of chest pain include musculoskeletal, anxiety, heartburn, etc. The treatment for these other causes of chest pain would be different than that for MVP and this is why it is important to determine the exact cause. The lifestyle modification that has been found to be effective for MVP symptoms like chest pain includes aerobic exercise training, the avoidance of stimulants (caffeine), alcohol and undue fatigue, and a reduction in stress. Regular aerobic exercise in people with symptomatic MVP was associated with decreased anxiety, increase general well-being, and a decrease in the frequency of chest pain, fatigue, and dizziness. Magnesium supplementation to individuals who are deficient in Magnesium and have symptomatic MVP was also associated with improvement in symptoms. Magnesium levels can be tested on simple blood tests to determine if you are deficient.
