Q:What does it mean when you have 2 heart valves?
Your mom probably has a Bicuspid aortic valve, that she was born with.. it means that the valve between her heart and the aorta has two valve leaflets instead of the usual three valve leaflets (not four) in normal people. Bicuspid aortic valve is caused by fusion of two of the three leaflets. It's a fairly common congenital condition, and is associated with a risk of aortic aneurysm (a weakening of the wall of the blood vessel which then causes ballooning of the vessel wall)...usually of the ascending aorta. All the best for her safe recovery.
Q:In a car, whats a valve/cylinder?
There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
Q:Mitral valve prolapse have impression on lifetime?
Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
Q:Coping with Mitral Valve Prolapse?
I also have mvp..diagnosed 15 years ago. I've been taking magnesium for over a year now and notice a big difference in the amount and duration of my mvp episodes. Also drinking plenty of water helps a lot. Good Luck
Q:Can any one tell me how can i make a one way valve at home?
R V parts stores have an item which allows a garden hose to be connected to the RV but the tank water inside the RV is not allowed to come out of the RV and enter the water hose (supply) so only fresh water comes in, nothing goes out.
Q:I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
The tyre should be fine, the problem is with the inner bike tube. It is useful to know what type of valve your bike tube uses. Schrader valves have a middle pin surrounded by an outer ring. Presta valves have a movable nut that allows you to inflate or deflate the tube. It sounds like your bike tube has a presta valve you have damaged the movable nut by loosening it a bit too much and/or being a bit too rough with it when using the bike pump. Unfortunately, it can't be fixed. If that is the case, you will need to buy a new bike tube (and keep a spare one handy as well) edit - That's weird, Schrader valves don't usually do that. It must have been an old tube or a faulty one. You'll be needing a new bike tube. edit - Well, I didn't know you could fix them, but still it'll be less hassle if you just brought another tube.
Q:1998 Crown Victoria Valve Chatter?
it is not valve chatter, it is called Pinging, it is a fairly common problem, what it is caused by is hot spots in the engine, or by overly advanced spark timing, i would check your base timing, perhaps even back it off a degree or two, i would also run a bottle of marvel mystery oil, or gm top engine cleaner through a vacuum line to burn out the crud that has built up, the sum total of these repairs: about 15 bucks, the savings: your engine! as for your t-bird, it was the pinging that broke the valve spring, not the tank of hi octane. hope this helps
Q:whats a leaking aortic valve?
The valves of your heart valve are not closing properly. Very common thing. May or may not require surgery. May or may not be related to you having a fast heart beat. Ask your dr to tell you what the racing heart was about. They would have a record if it was significant. Or your doctor may want you to wear a monitor for 1-2 days to help to catch this so it can be identified.
Q:what is a imt valve the ecm has detected that the imt valve is stuck open?
Remove it and clean it.
Q:Dump Valve!?!?!?!?!?
if i remember rite you can adjust the control settings for your dump valve so that it will dump at a lower pressure and a lower pressure dump should also give you the sound that you are looking for.
