Hi, I'm Harry and I need some help. I have many heart defects and I'm struggling to live. I've heard that there are many artificial heart aids that will help me to live. I need you to help me decide which is best.
An artificial heart is a device implanted within the body, in addition to the original, defected heart. The surgically installed pump provides circulation and replaces heart ventricles (usually the left ventricle which is the dominant chamber involved in pumping blood around the body). Artificial hearts are beneficial because they provide a permanent solution to hearts which can aid hearts, when heart transplants are unavailable. However, the surgery can lead to serious complications, like blood clots or infection.
Heart valves exist naturally within the heart, and separate the heart chambers and blood vessels, they constantly regulate blood flow. Healthy valves minimise obstruction within the heart and allow blood to flow smoothly. Heart valve disease can affect the flow of blood through the heart,if a valve does not open or close properly it will obstruct the flow of blood or allow blood to leak backwards. Symptoms include: being out of breath, swelling of the ankles and feet, and fatigue. Artificial valves can be implanted, or a pig’s valves could be used, this requires open heart surgery which can cause infection, etc.
Stents are small mesh tubes used to treat narrow or weak arteries, preventing heart disease and therefore heart attacks. Stents are implanted during PCI (angioplasty) which restores blood flow and the stent itself supports the inner wall of the artery.Stents are beneficial because they prevent the coronary artery from narrowing and blood clotting, and prevents the need for coronary bypass surgery. However they can induce allergies and blood can still form within the stent.
Pacemakers are small electrical devices fitted in to the chest/abdomen to regulate heart rate (because of abnormal heart rhythms, miss beats, etc), by artificially replacing the sinus node; sending an electrical impulse to your heart. Pacemakers can eliminate the symptoms of Bradycardia, allowing individuals to have more energy and less shortness of breath, however the pacemaker will not prevent heart attacks and if the pacemaker malfunctions (because of exposure to a magnetic field, gas appliances, etc) fatalities could occur.
