- Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
- The tissue is most like ours. Yes, they are still used. They have a low rate of rejection.
- Q: I am 16, and i have a leaky heart valve. What makes it worse so i can try to prevent from it getting worse? please help.
- It would be very helpful to know which valve is involved. At your age a bicuspid aortic valve would be the most common congenital heart lesion. Regurgitation tends to increase over time no matter what is done. There is nothing that you will be able to do to prevent this from getting worse if that is the nature of the valvular abnormality. If you provide me with additional information I may be able to offer a more thorough and thoughtful response. I wish you the very best of health and in all things may God bless. JR
- Q: The water won't drain around my outside shutoff valve. The faucet at the valve is not dripping any water. Could it be underground problem?
- i don,t understand your Question.
- Q: I have mitral valve prolapse, I want to continue lifting weights.. Can i lift weights?here's my latest echo result.1. Normal left ventricular size with non-thickened walls with adequate wall motion and systolic function (EF = 70%)2. Normal left atrium without intracardiac thrombus3. Normal right atrium, right ventricle, main pulmonary artery and aortic root dimensions.4. The anterior mitral valve leaflet prolapses into the left atrium during ventricular systole.5. Structurally normal aortic valve, tricuspid valve and pulmonic valve.6. No pericardial effusion noted.COLOR FLOW DOPPLER STUDY:No abnormal color flow display across the valves, interatrial and interventricular septae.Normal pulmonary artery pressure by acceleration time.
- Good question, excellent details! The best advice I can give you, due to the complications associated with mitral valve prolapse, I would recommend you perform a stress test. Real easy procedure, heart rate is increased, generally by mechanical motion (ig running), cardiac cycle is monitored on screen. Basically here is the problem, your flaps on your mitral valve are being pushed back into the region of your heart that feeds the contracting area (left atrium), contracting region being the left ventricle. When this occurs, it greatly increases the possibility of back-flow of blood to the pulmonary veins and back to the lungs, which is REALLY bad. Without going into further detail, my best recommendation would be a stress test. Hope that helped. Good luck.
- Q: We've got a one-handled faucet for the tub/shower and it has that pressure-balancing mechanism. We have it set, I think, so that we can take the hottest showers possible, because our water heater lacks enthusiasm. However, when I want to draw a bath for the baby, I need it to be lukewarm - and I have to turn it almost OFF to get the water to be even tepid. I can't get cold water out unless it's only trickling. As far as I can tell, our cold water pressure isn't different from the hot (bathroom faucets are 2 handles and H C seem to be about the same pressure). Is there a way to adjust the valve in the shower so I can get both the hottest possible, and the coldest possible water at full pressure?
- All major manufactures of valves have excellent customer service departments. Most of them also have great websites with lots of technical info. Note: You may try changing your shower head to one that is a higher flow or remove any flow restrictor that may be in the one you have now. This may allow you to have the valve set to a colder setting for the tub spout and should increase the hot when showering. Personally, I don't like these style valves. Too many problems like yours.
- Q: Leak in Heart Valve ?i was told by my doctor to to do a ultra sound on my heart a few weeks ago, wehn i finished the ultra sound the lady that did the scan asked if i had any type of heart disease in my family, and i responded that i dont, she said that i have a leak in my heart valve, but that was all, i dont have an appointment with my doctor til two weeks from now, i THINK i feel shortness of breath, but i feel like this may all be because im scared ...... main thing is has anyone had this or know anything about this is it dangerous, deadly ? should i be scared ?
- It depends on what valve is leaking, how much is leaking, and for how long has it been leaking. Wait for the physician to evaluate the echocardiogram. Technicians are often wrong or limited in their evaluation, as they are not trained in in-depth evaluation of echocardiographic studies like a cardiologist. Make an appointment with your doctor to discuss the results. You said you think you have shortness of breath, make sure you mention that when you make your appointment. Only your doctor will be able to determine if it is related to your heart, or due to anxiety, or from something else.
- Q: why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?
- Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.
- Q: according to my study only indurial gate valves have both rising and non rising stem through handwheel and it seems that it doesnot apply to golbe valve and globe valves are only non rising stem. i wanted to know if this is right
- The valve in the upper left quadrant of the picture on this web page is a rising stem globe valve. This type of globe valve is common in cast steel and forged steel valves like those used in the oil and gas industry. They can be as small as 3/4 up to about 8 sizes.
- Q: I need an angle valve for my sink buts its a bit of an odd size. I have copper tubing at 1/2 i need a valve preferably compression that can feed to a water supply that is 1/2 Pipe thread.Included images of the supply hose valve to sink. To help show what i'm looking for.
- If you're looking for a valve that attaches to a 1/2 iron pipe coming out of the wall, and then will feed to 1/2 copper tubing, then you're looking for- an angle stop, 1/2 female iron pipe to 1/2 compression. Just about any good hardware store will have it in stock or be able to order it, just be sure that they know what you need. I've often found that using visual aids,like a piece of pipe in one hand, and a piece of tubing in the other, with an empty space, waiting for a valve, between them, can be an invaluable aid to communication. Don't even try to cut and adapt a braided hose. The stainless braid contains a (relatively thin) rubber hose. Without the braid to reinforce it, it will burst. If you need to adapt plumbing, there is always a way to get water from point A to point B. The challenge is finding the most elegant route.
- Q: I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.
- What your looking for is a check valve. Home Depot Be careful, very careful!
