Can Stem Cells Be Applied In Heart Valve Transplant Right Now
Presently, no: There is a center in kansas city working on this very thing but it is currently at the animal level of experimentation. This is a great question and someday, if this procedure is perfected to use in humans, it will revolutionize pediatric valve surgery as the valve will grow with the recipient, obviating the need for reoperation. ...Read moreSee 2 more doctor answers
In medicine: a transfer from one body or body part to another of an organ (liver, heart, lung, kidney, pancreas bowel) or tissue (hand, face, hair). The immune system fights foreign invaders (like infections) so it will reject transplants from other people (allotransplants) because they look like infections. So transplants usually require drugs to ...Read more

During heart transplant surgery. How is blood flow kept to the brain since the heart has to be taken out?
Heart lung machine: During heart transplant and in fact many types of heart surgery the patient is connected to cardiopulmonary bypass machine. . The blood is drained out from the large veins (vena cava) into the machine. Oxygen is put into the blood and it is returned into the artery system usually the aorta. So even with the heart stopped, the body and brain continue to receive blood and oxygen. ...Read moreSee 2 more doctor answers

Renal hypertension: Permanent cure???? Nothing can promise permanent resolution of his problems. Studies and experience have shown that in most such patients, surgery ( resection of smaller blood vessel) can accentuate problems. However in some cases such surgeries can cause some relief. Your nephrologist and a good vascular surgeon should be able to give you best advice. ...Read more

My friend has 6 stents a pacemaker defibulator and the back of his heart is dead. How can someone live with their heart half dead?
Slowly: The heart is a muscle, and uses electricity to generate the "squeeze" necessary to get blood to the whole body. Stents keep blood flowing to the muscle, and a pacer/defibrillator keeps the electricity on and timed right. When part of the heart is dead, patients are less active. They also may develop congestive heart failure, with fluid backing up into lungs. Pills can help. ...Read more

Sounds great: I am not aware of any studies that promise availability in 10yr. Once a technique has been demonstrated in animal models, there are many channels that must be navigated to test in humans, and then clinical trials, for years, before final fda approval. I suspect it will come, but 10 yrs seems too short an interval. ...Read moreSee 3 more doctor answers
If not treated, can severe sleep apnea damage heart enough to cause significant drop in left ventricle ejection fracture? In 1 yr from over 50% to 12%
Possibly but...: Severe sleep apnea typically leads to raised pressure in the pulmonary artery which in turn causes increase in pressure in the right ventricle. When talking about ejection fraction, it is usually referred to the left ventricle that is responsible for blood distribution. Right heart failure may lead to left heart (ventricle) failure. Also, sa may contribute to hypertension that may cause ef decline. ...Read moreSee 2 more doctor answers
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
