Q:I was told Wed. that I need to have my aortic valve replaced. I was wondering if anyone could share their experience with this surgery good or bad. I am meeting with the surgeon on the 26th, and am very nervous. Any tips and or suggestions appreciated. I'm a 39 year old female.Thanks in advance
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:Why is the atrioventricular valve in the right ventricle called the tricupsid valve and the atrioventricular valve on the left ventricle called the bicupsid valve?
Bicuspid has to flaps and the tricuspid has 3 flaps
Q:I assembled my new gas grill, but I'm not sure if the burner pipes (aka venturi) are properly connected to the valves. My assembly matches the picture in the instruction manual, but I'm not sure if the seal is tight enough. How do I know? Do I attach the propane and test? I'm concerned about the safety of doing so. Thanks!
You should call the customer service number on the paperwork that should have came with the grill.
Q:I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.
well, is the car in good shape otherwise, like the tranny, suspension and the body?, if it is, then its probably wort a valve job, its cheaper then another motor.
Q:im 28yrs old with two babies.in my heart two valves are very tight and leaking too,im going for a transplanting them in august.If there is anybody who got this problem solved please share.Thanks in advance.
Usually with an artificial valve, you'll need to be on a blood thinner for the rest of your life. If they use a natural valve, you usually won't need the blood thinner - perhaps you will for a little while, but not permanently. You can request a natural valve, but the surgeon doesn't know what size/shape of valve you need until he actually opens you up and sees what he's working with. He has an idea, based on the x-rays and MRIs you've had done, but he won't know for sure until he actually see it. So the surgeons are going to request that the Organ Procurement Department to thaw out two or three valves, depending on what they see in the tests. You can't just keep thawing out valaves, testing them, and then refreezing them if they aren't what you are looking for, so if they turn out to not be a good fit, he's going to turn to an artificial valve. So you could request a natural valve, but because of the shape of the gap that he needs to fill, you may have to have an artificial valve. Blood thinners scare people, and your friends will tell you horror stories about how their uncle's cousin's Nephew cut his arm and bled to death because he was on a blood thinner! That could happen, but it is very rare. What does happen is that you will have to go to your doctor once a month and have a blood test, and if your blood is too thin, you need to ease off on the blood thinning medication. Or if it is too thick, you need to take more. If you're blood is too thin, you'll bruise more easily - which might be embarrassing if the bruise can be seen. Blood thinners aren't as dangerous as they make them out to be, but they can be inconvenient!
Q:I got a '99 bmw 740il that is leaking and burning oil. It shoots smoke out the exhaust when i first start it from burning oil. And the car misfires when idling, i did a tune up and the spark plugs were soaked in oil causing the tune up not to help anything for long cause it was missfiring the next day. Does this sound like the valve stem seals? I bought new valve cover gaskets and grommets and im gonna replace those this weekend, im hoping that will help. Comments please
The symptom of bad valve stem seals is blue smoke after sitting overnight. But once that smoke is gone, a bad valve stem seal won't have any effect on engine running or idling. And it certainly won't cause a misfire. Worn valve guides can do all those things. You have far more serious problems than just valve stem seals. Get a wet/dry compression test and a cylinder leakdown test to isolate the problem to either valves or rings.
Q:I don't know the principle of operation of the butterfly valve. Can I control the percentage of opening by an analog output from the PLC?
A butterfly valve does not have an overall linear characteristic and is a poor modulation controller through its full range of operation. It will need a stout shaft and a tough actuator. It will be most linear in about the 30% to 60% open range. To make a full linear controller, you will need to have the actuator-controller- valve , single source supplier know what control feature you wish to accomplish in the fluid system and what the controlling signal will be. Any cotrol valve is a variable resistance added in the whole dynamic system which itself will have an inherent second order friction loss flow characteristic.
Q:I have a 97 ranger 4.0L that takes 10w-30 and I'm going to be changing the oil soon. It has some valve clatter I'm just wondering if I can use a thicker oil such as 15w-30 or maybe a 10w40?
10W40 works fine. That's all I've ever run in my Explorer - and presently it has just under 200,000 miles.
Q:Would it be cheaper to get a toyota Valve body U140/240 repaired or would it be easier to swap it out... by the way the transmission valve body would cost $780
LOL okorder DETROIT MICHIGAN! $780, my SORE LEFT FOOT!
Q:i went to the heart doc today to get the results from an echocardiogram and he told me i had two leakages in one of the valves of my heart. i dont know why, but i didnt even bother to ask him exactly what that meant because he told me it was nothing to worry about. can anyone tell me more about this?
Hum...it depends how bad your leakage is. If it causes too much blood to flow in the wrong direction it could cause an enlarged heart. What lead up to you having an echocardiogram? My son has has epstines malformation of the tricuspid valve and it caused leakage. It depends on the level of the leakage. It can be a big issue but obviously your leakages are small and nothing to be concerned with? I would def. call him and get some clarification....
