Heart valves grown from womb fluid cells
Common Questions and Answers about Heart valves grown from womb fluid cells
heart
An echocardiogram uses the same machine Doctors use to see a baby developing in the womb and listening to the babys heart beat. You basically lay on your side and the Doctor runs a small hand held probe overy your chest, using gel, and this gives images on the monitor. It allows many things to be checked and is a great tool for investigating heart problems. It will show the dimensions of your heart, including the internal chamber volumes.
That kind of therapy is not readily available yet. New hearts can be grown using cells from our own body, reprogrammed to become whatever the lab tells it. Complete working rabbit/mice hearts have been grown in a lab, but I don't think human ones have yet. However, I believe they will be in the next ten years. This kind of research takes a long time because they have to see how the hearts behave relatively long term.
I recently found out that my (not very close) friend has a heart defect - a missing valve. He lives a normal life, although he's not recommended to do sports or some hard chores. I'm very worried about him, since I don't know anything about heart diseases, so I decided to ask you for any information about this kind of disease and what could be the major problems it can cause. Will he need an obligatory operation after some time? How dangerous it is?
The coronary arteries are not the vessels which actually feed the heart with blood to be pumped through the valves and through the body. Your heart would not receive any more blood into the chambers with the artery being opened up. Your heart may simply be working more efficiently and pumping more blood with each cycle. More likely the valves had problems before but wasn't discovered or the condition was very mild then. Are the valves leaking mild/moderate or severe?
chamber filling), and repolarization (discharging...contractility of chamber) heart cells. In arterial smooth muscle cells, intracellular calcium paradoxically controls both contraction and relaxation.... The mechanisms by which calcium can differentially regulate diverse physiological responses within a single cell remain unresolved.... Calcium-dependent relaxation is mediated by local calcium release from the sarcoplasmic reticulum.

Sometimes, as in my case, five years ago I had ischemiac (lack of blood flow) from occluded vessels and a silent heart attack. The heart cells were stunned and impaired the contractions (EF 13-29%). Stenting a blocked artery provided sufficient blood flow and contractions returned to a normal EF 59%. Also, the left ventricle was enlarged and medication has returned the LV to normal dimensions.
I cannot figure out how they did not know that her heart valves were bad. They could have done open heart surgery, bypass and fixed the valves in one operation. Was she short of breath before this all happened? When heart valves are bad, a person becomes short of breath. Climbing stairs is hard, energy level drops, easily tired. Chest pains are usually caused by plugged arteries. It does happened when the artery tears during a stent placement. Sometimes the artery is weak.
d ask your doctor if you should have a nuclear stress test to look for a blockage in your heart arteries, and/or a heart echo to look at valves, etc. Breathlessness very well could mean you have blockage which causes one to have your symptoms.
After heart attacks, I had to be on carvedilol to allow my heart to try and establish new little arteries and to repair stunned heart cells.
I thought I had a respiratory problem with symptoms of a dry cough, but it turned out I had had a silent heart attack and lung edema, and there was some damage to the heart cells (hypokenisis...impaired heart wall movement). Treatment revitalized the heart cells and the heart is now pumping adequately.
Hope this helps.
Other condtions that will reduce the cardiac output can be heart valves, heart muscle disease from drugs, alchohol, some mediations, etc., the reduced output causes the heart walls thicken pathologically (athletes' heart walls increase non-pathologically).
....so an enlargement can be heart wall thickening or dilation (remodel).
If the heart is remodeled or wall thickened and in an advanced state that can cause a lower than normal cardiac output.
Did the doctors order any other tests such as an echocardiogram to check your heart function? To me, it sounds like you have fluid overload perhaps from a weakened heart. I am not a doctor, so please take what I say with a grain of salt. I am merely speculating from what you have written. You should really ask your doctor about any diagnostic tests and why you are on medications etc...
The pills you were/are on are diuretics, such as Lasix or furosemide.
The problems with this valve are that they do not grow with the child, and they require anticoagulation to prevent them from clotting. Because of the low velocity flow on the right side of the heart and concern for clotting, mechanical valves have not routinely been used in the pulmonary position, though there are some places that are re-examining this concept.
Finally, something that has been on the horizon for a while is the concept of a tissue-engineered valve.
The valve is meant to allow blood to flow only one way -- that is, outward from the heart -- and if a valve is regurgitating, then there is a degree of backward blood flow. In other words, the valve is leaking. Again, mild is mild. Not a lot of blood is flowing the wrong way, but some is -- enough that the doctors can see it on an echocardiogram. Another word that you may hear, that means the same thing as regurgitation, is incompetence.
Quick treatment can revitalize stunned heart cells, but if the heart cells are dead, complete recovery may not happen.
With damaged heart cells, heart chamber walls are impaired and this causes weak contractions. Weak contraction reduces the heart's ability to adequately pump enough oxygenated blood to meet the system's demand.
In other words, it is possible that you carry a gene that will increase your risk of developing heart failure (in fact, if you are retaining significant fluid as you suggest, you may have a mild form of heart failure already). On the other hand, despite a family history of heart failure, this does not mean that you will develop it (even if you carry the gene).
Indirect measurements are taken using pressures in each chamber of the heart. For example, if my tricuspid valve is leaking alot of blood from my right ventricle, into my atria, the additional fluid in the atria will cause the atria to have more fluid pressure inside of it. This pressure can be estimated through my venacava by observing whether or not this giant vein still collapses when I 'sniff' or inhale.
4. These measurements are taken from different angles.
For some insight, sepsis is a bacterial infection in the bloodstream or body tissues, and in order to make a diagnosis of sepsis, at least two of the following must occur: a heart rate above 90 beats per minute, hyperventilation (more than 20 breaths per minute) and white blood cell count below below 4000 cells/mm.
You haven't listed any symptoms so for a perspective frequently, people use the term sepsis to describe 'severe sepsis' and 'septic shock.
An inferior infarct is damaged heart cells. An echo views the beating heart and if there is damaged heart tissues the heart wall will impair heart wall movement...medically termed hypokinesis for some impairment and akinesis for necrotic heart cells.
Some valve insufficiency is oftened considered medically insignificant and does not advance nor present any problems.
Hope this helps. Take care.
