Q:It has been known that although tissue valves have lower rates of thrombotic episodescompared with mechanical valves, they are difficult to procure, and their longevity has not yet been proven. Is this true as of 2007? Thanks for answering.: Tissue valves do last as long as mechanical valves in most cases. Most of those are porcine valves, and some are bovine. The majority of those are used to replace the aortic valve. The mitral is almost always replaced with a mechanical valve.

Q:I recently converted my furnace from l.p. gas to natural gas. It's been maybe two weeks of me troubleshooting and replacing. I have a new gas valve and transformer in the furnace. There is 24v running to the valve and it clicks to open but no gas comes out. I have exhausted all my options with the mechanical/electrical components on the furnace. I have bled the valve to be sure that there was gas making it to the inlet side. Does anyone have an idea as to why the valve stopped opening once I converted it over?: may sound like a stupid answer but there is an arrow on the bottom of the gas valve and i have seen them put in backwards,or it sez inlet on 1 end,,make sure the knob is turned to on,make sure the arrow is pointing towards the burners

Q:And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?: i would not worry about replacing the wsher inside the valve...U can go to about any home improvement store and just buy a new valve for around $10...so if they have a quarter turn valve...those will serve u best in the future plus it is a ball valve which doesnt use a washer but a ball inside turn so it is a better seal...just drain the water heater then unscrew the old one and put pipe sealant on the thread of the new one and just screw it back in and fill ur water heater back up and ur done..

Q:A diabetic patient undergone CABG having aortic valve problem.Cardiologist suggested valve replacement: Today, there are two types of prosthetic valves used for replacement: mechanical or tissue. Mechanical Valves A mechanical valve is carefully designed to mimic the native heart valve. It has a ring, like your own natural heart valve, to support the leaflets. Like your own heart valve, the mechanical valve opens and closes with each heartbeat, permitting proper blood flow through the heart. To prevent any blood clots from developing on the valve, which can cause complications, a mechanical valve replacement requires you to take anticoagulation medicine (blood thinners) daily. The dosage of this medication is different for each person, so you will be closely monitored to make sure you are on the correct dosage for you. Regular blood tests will be performed at the physician's office, an anticoagulation clinic, or at home with a specialized testing kit. Tissue Valves The tissue valve is a native valve taken from an animal. Once the tissue is explanted (removed), it is chemically treated and prepared for human use. Some tissue valves have a frame, or stent, that supports the valve, and some valves are stentless (no framework). A very thin polyester mesh cuff is sewn around the outside of the valve for easier implantation. Eliminating the stent makes it possible for the surgeon to implant a larger valve. Larger valves generally provide more surface area for blood flow; this allows more blood to flow through the valve to accommodate the body's needs. Homografts or Allografts A homograft or allograft is a human valve obtained from a donor. This type of valve is particularly beneficial for pregnant women and children, because it does not require long-term anticoagulation therapy. In addition, it can provide excellent hemodynamic performance, allowing for natural function of the surrounding structures. Because the availability of these valves depends on donors, supply is limited. Take care always

Q:When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!: it is a common cause of murmurs in children, and ordinarily they grow out of it, you can relax.

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.: i exchange into an open coronary heart RN. we frequently operated on people for the 2nd time, often desiring valve replacements. an consumer-friendly hassle after a 2nd time around open coronary heart surgical treatment is bleeding. the 1st 12 hours is extreme. countless those victims pull by using and do only extreme high quality. stable fulfillment with your Dad.

Q:also are those air flow limiting valves safe for the air pump to reduce the flow of air, I have one because the air bubbles are just way too many without one and it scares the fish away: a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.

Q:I got a cold air intake installed on my vehicle and don't have any AEM bypass valve installed, for preventing hydrolock. If I drill a small hole(e.g 1cm) on the intake(short ram section) can that prevent hydrolock or do I still have to get one of those bypass valves?I'm looking for any alternatives, instead of those AEM bypass valves and was wondering if drilling a small hole in the cold air intake could help in preventing hydrolock, just as good as the AEM bypass valve.: Only version 1 of the AEM CAI's could even use the bypass valve. Version 2 will not work with this bypass. This bypass valve is pressure sensitive and set up to open if the air flow was blocked at the filter. It also has a foam filter on it to still give you some filtration of the air. You do not want to drill a hole in the intake. This will allow unfiltered air to enter your intake and reduce the efficiency of the intake system. I'm not sure what kind of car you have this system on, but on my Accord, the filter was moved down inside the front bumper just in front of the drivers tire. It is surrounded by plastic and has minimal chance of any water splashing in to it. The only way I can see water getting to it is if I were to try and drive in to a large Pool of water in which it would have to be higher than the floor of the car. Anyone who would even attempt such a thing would be a fool in the first place for trying to run through such high water. If you have the Version 1 AEM, get the bypass valve. Don't drill holes. If you have the Version 2 which can not use this valve, just don't try to use your car as a boat. You shouldn't have any problems. TGP

Q:Im trying to replace the egr valve on a 97 lincoln continental. I need to find out what size wrench I need, to get the nut off. Do you know?: I am assuming you want to replace the EGR valve because you are getting an insufficient EGR flow trouble code. Before you replace a perfectly good valve with an inferior aftermarket part that will likely fix nothing, a little more diagnosis is in order. If you have access to a scan tool and a vacuum gauge, perform a KOER (key on engine running) test on the engine with the vacuum gauge connected to the hose to the EGR valve. When self-test reaches the EGR test, look for the vacuum guage to move during the self test. If it moves, the vacuum source and EGR solenoid are good. If not, trace the vacuum harness for leaks. Without the scanner and vacuum gauge, find a length of hose and suck on the hose, or connect to other vacuum source to test the valve. You are looking for an RPM drop at idle when you open the valve in this way. I suspect your problem is a passageway clogged with carbon. Remove the valve and throttle body to access the clogged areas and manually decarbonize. This is the most common reason for an insufficient EGR flow on a Lincoln, along with a faulty DPFE sensor or related hoses. My money is on the clogged passages or the bad DPFE sensor.
