What is the aortic valvuloplastics?
aortic valvuloplastics, also known as balloon valvuloplastics or aortic balloon valvuloplastics, is a minimally invasive procedure that involves introducing a balloon catheter into a narrowed heart valve to expand. The catheter, which is a thin tube with an inflatable balloon at its tip, is used instead of surgery, which is much more invasive. Aortic valvuloplasty is used in cases of stenosis, which is a narrowing of heart valves.
This procedure based on a balloon catheter is named after a specific part of the heart it intends to heal, aortic valve. This is one of the two semilunar valves that leave the heart; The second SL valve is the lung valve. Aortic valvuloplasty candidates usually suffer from aortic valve stenosis, a type of heart disease that concerns the narrowing of the aortic valve, as well as by hardening due to calcium accumulation. Such a torment limits the amount of blood flow and thus adversely affecting the function of the heart, what depends on the bloodfrom one chamber to another. This can lead to congestive heart failure if it is not immediately solved.
Aortic valvuloplastics has this problem to correct. The tip of the catheter containing the balloon is inserted into the blood vessel by a small cut in the weakness. The stenotic flap with video monitor and X -ray leads to open. Once there is, the balloon is inflated to expand it by opening his leaflets. Although aortic valvuloplasty can also be used for other heart valves, it works best for the aortic valve.
People undergoing aortic valvuloplastic must not eat about six hours before the procedure. Candidates for this operation should also be aware of the main complications that could occur. These include embolism, which is a clot with a clot; Hematoma or blood collection outside a blod vessel; infection; irregular heart rhythm; and heart attack.
Medical community enthusiasticShe welcomed the aortic valvuloplastics at the end of the 80's. Over time, however, doctors have doubted that the procedure can be used as a long -term solution for stenosis over temporary reliefs of symptoms and improved heart function. At the beginning of 2000, scientists began experimenting with the replacement of percutaneous aortic valve, which includes the introduction of synthetic heart valves rather than simply opening the original, defective. This procedure is now officially known as the implantation of the aortic flap Transcatheter (Tavi) and is charged as a significant improvement compared to aortic valvuloplastics. Tavi is used in Europe, but is still in the States of Clinical Evaluation in the State Testing phase.
