Q:A question about tricuspid valve disease..?
Tricuspid valve disease refers to abnormal function of the tricuspid valve. Two types of tricuspid disease include: Tricuspid regurgitation - the valve is leaky or doesn't close tight enough, causing blood to leak backwards across the valve Tricuspid stenosis - the valve leaflets are stiff and do not open widely enough, causing a restriction in the forward flow of blood. Your physician may refer to this as an increased pressure gradient across the valve, found by echocardiogram or cardiac catheterization. How is it treated? Medical Management Your doctor will want to monitor the progress of your valve disease with regular appointments. They may be spaced once a year or more often, if your doctor feels you need to be followed more closely. Your appointment will include a medical exam. Diagnostic studies may be repeated at regular intervals. Your physician may prescribe medications to treat your symptoms. These medications may include drugs to treat heart failure or medications to control irregular heart rhythms. Lanyard and template handle assists with placement of ring Surgical Management Tricuspid Valve Repair When valve disease is severe, it may be necessary to repair or replace the diseased valve. Tricuspid valve repair using an annuloplasty ring is the preferred surgical approach for tricuspid regurgitation and may be performed for primary tricuspid disease or for combined cases with other valve surgery (mitral, aortic). See illustrations to the right. For more information and to view actual surgery, see: Movie: Edwards MC 3Tricuspid Annuloplasty* NOTE: Son, these patients are depressed, so they avoid discussing their condition.So the best way keep them happy as if nothing is wrong with them.OK Hope it helped you out.

Q:how to replace an egr valve on a 2002 mercury sable?
Un plug the vacuum hose on top of the valve, loosen and remove the big tube nut on the bottom of the valve, I have found if you hit it sharply with a hammer 3 or 4 times before you try to loosen it won't break the valve off, once the tube nut is undone remove the 2 bolts holding the EGR valve to the intake manifold. Remove and discard the gasket and install the new valve in the reverse order. If the tube nut still won't come loose try heating it with a torch, if it's really rusted on you might have to replace the EGR tub along with the valve.
Q:Tire valve stuck on my bike?
What causes the valve stem to get like that. is from riding it with an almost flat tire with very little air in it. . Let the all the air out of the tube ,. pull and tug on the tire to rotate it on the rim until the valve stem is standing strait up again. Then refill with air. But often when you ride with low air, it ends up making a hole in the tube.
Q:how do you reconnect the heater valve on a 1997 ford ranger 2.3l 4 cylinder?
You okorder.com for info. They have a great repair section that's free after you sign up. Manuals have lots of photos which should take care of your question.
Q:I am getting a valve job...?
Getting a vlave job done isnt going to hurt your car at all, nor your motor. Make sure you have a reputable machine shop do this (most garages dont have the tools for it). If a 3 angle valve job is done correctly and new valve stem seals, retainers, and spring are all carefully installed to manufacturer spec then there should be no problem at all. Many shops will do a sloppy job grinding the valve face (which is a hard thing to get the knack for) and will install to valves without another thought. When new valves or old valves with resurfaced faces are installed the spring rate of the valve springs needs to be checked to ensure are srpings are the same strength. Also once installed, the height of each installed valve/spring needs to be checked to make sure its in the specified allowance. If valve seats and surfaces are all done correctly along with a profesional installation I wouldn't worry!
Q:Leaking metal Tyre valve stem?
On that year car the tire is tubeless and the valve stem should not be moving as it would if you had a tube type tire. If the valve stem is pushing in it means you drove on the tire while flat and probably ruined the tire as well as the valve stem. The tire must come off the rim to be inspected before blowing it back up and used. If you don't inspect the tire it will probably blow out at highway speeds and kill someone!
Q:Trumpet problems! No noise, just air! Valves sticking!?
Dis is a pretty common problem. The valves are in the wrong valve case or they are turned aound in the case. Take each valve out and check the number...... most have a number stamped near the top, or on the part around the spring. Get them in the right place with the notch in the case matching the little peg on the side of the valve and all should be well. By the way, if you can't get a buzz on the mouthpiece the whole problem is you alone.
Q:Testing my EGR valve?
Most it could go either way depending upon the failure mode (stuck open, stuck closed, leaking, etc). I use a hand operated vacuum pump ($20 at most car parts stores). Connect it and see if you can draw a vacuum and if it holds the vacuum That will tell you if the diaphragm is okay. Also check the valve seat itself to see if it seals properly when closed. EGR valves run about $20-$50 depending upon car. Also, just because the EGR valve isn't working does not mean the valve is bad. You could have a faulty or disconnected vacuum line preventing the valve from operating. That was my problem in stead of replacing the EGR valve and the catalytic converter as recommended by an Emission Repair Station located just outside the state emission test station. The repair station is no longer in business.
Q:96 chevy cavalier heater control valve?
The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......
