Q: hi My Dad is 65 yrs old. he is very fit and healthy. He has had heart problems as long as i remmember! he has been under care for almost 2 years now and he has had to stents put in. Now the doctor has found out that his Mitral valve is leaking. They have told him tat he needs surgery to either have the valve replaced or repaired. i like to know if anyone out there has been through this and can help ease this a little as Ia really worried!! Thank you!: Mitral valve surgery is surgery to either repair or replace the mitral valve in your heart. Minimally invasive mitral valve surgery is done through much smaller incisions (cuts). In open surgery, the surgeon makes a large incision (cut) in your breastbone to reach the heart. Mechanical heart valves do not fail often. However, blood clots develop on them. If a blood clot forms, you may have a stroke. Bleeding can occur, but this is rare. Biological valves tend to fail over time. But they have a lower risk of blood clots.

Q: what is the difference between mitral valve prolapes and mitral regurgitation?: Mitral valve prolapse refers to a condition in which the leaflets of the valve are large and floppy compared to the average. When the ventricle contracts, the valve closes and the flow causes a pop as the floppy leaflet fills with blood, much like the way the wind fills a sail. This extra pop can be heard with a stethoscope (like a click) but it can often be felt by the person affected which makes them more aware of their heartbeat than the rest of us. Mitral Valve regurgitation is a condition in which the mitral valve leaks after it is closed leading to a loss of efficiency of blood pumping and a drop in blood pressure. It is often a small leak and is of little consequence and is often associated with mitral valve prolapse. This leak can sometimes be heard with a stethoscope as a murmur under the left arm. The combination of both situations is known as Barlow's click-murmur syndrome. Old Doc

Q: hi im 13 years old and i am having my tricuspid valve repaired or replaced the doctors do know what they are going to do yet.what is the success rate of the operation ?and whats the survival rate of the operation ?all other info would be appreciatedthanksalex: Any type of valve surgery involves exposing the aorta of the heart, therefore it is a form of open heart surgery. Over time, this has become a relatively basic procedure for heart doctors and it has a success rate of almost 80-95%. There is a chance that you might need another surgery afterwards, but that only happens in about 5-10% of patients that get the surgery. The survival rate for this operation is very high and only 5-10% of patients experience any negative effects during the surgery. This includes infection, stroke, allergic reaction, or bleeding. I will keep you in my prayers Alex. Best of luck to you!

Q: I have a mountain bike that my brothers left me. the tire in the front is a normal s valve, the one in the back is a presta valve. now this was ok because it was fully pumped up, but then it popped on the road, so i got a new tire ad put it on and was all ready to pump it up but when i tried to pump it no air would go in. so i looked at it a while and i figured out the top unscrews, so i unscrewed it and put the pump back on and started pumping, but after a while i figured out that no air was going in the tire and now i'm very confused.: A presta valve can be a little finicky. If you don't push the pump nozzle down far enough, it won't let the air into the tube. Unscrew the valve, line up the pump head with the valve stem, push down firmly while twisting back and forth. Try pumping; if it builds up pressure, just push it down until it releases into the tire. Don't forget to pull up the lever on the pump nozzle.

Q: my valves got dirty long story how do you clean them: Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.

Q: I have a 1993 Jeep Grand Cherokee 5.2L V8 I posted a question on here before and many thanks, What I had was a bent rod well I took off the head and removed all the valve springs and found that where the bent rod was the valve stems are bent too. What else do I need to do? or can I clean the head up make sure no valve holes are bent, replace the rods and valves and be good to go. I want my jeep running again!!! Thanks: I'd say the timing chain either broke or the cam gear is worn off,cam gears used to be made of fiber rather than steel on older engines. When the cam stops turning the valves stop working and when the piston comes up it then hits any valves that are open bending the valve or push rod or both. If this particular engine is run by a belt and the belt breaks you get the same result. To check this you can take the timing cover loose on the front of the engine and check the condition of the chain and gear.

Q: I have a 04 Ford Ranger 4.0L . some people are saying that headers may affect the EGR valves and might put up the check engine light on. is this true or not.: The headers shouldn't effect the valves but you will have to tighten the headers every day and you will be looking at alot of ehaust leaks from them.

Q: Okay, so veins have valves to help counteract the pull of gravity. I'm wondering, do the veins in the head have this same adaptation, seeing as these veins are simply bringing blood down to the heart, and are not pulling against gravity.: Valves counteract the pull of gravity. They also prevent blood clotting. Yes, because if they didn't, the blood could flow too fast and pool in your veins, which causes blood clots, which isn't good. So to monitor the amount of blood going through veins in the head or neck, the valves close, and open. Hope I helped. -Selene

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.: There are four valves in the human heart (Mitral valve, tricuspid valve, aortic valve and pulmonary valve). If the heart valve is leaky, the doctor can hear heart murmurs through the stethoscope. Leaky valve may cause bacterial endocarditis, heart palpitations or even heart attack. Medications will be administered for prolonged period to control the heart disease complications. Echocardiography report will clearly state which heart valve is leaking.
