Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...
The catheter/stent system is introduced into the body by penetrating a peripheral artery (an artery located in the arm or leg) and passed through the arterial system to deliver the DES into the blocked coronary artery. The stent is then expanded to dilate (open) blocked or narrowed coronary arteries (narrowed by plaque buildup), caused by a ...
The most common treatments are medications and surgery to repair the damaged blood vessels in your brain. Valvular heart disease Heart valve problems may be treated with medications or surgery.
Restenosis rates of drug-eluting stents appear to be significantly lower than bare-metal stents, and research is underway to determine if drug-coated balloons also improve restenosis outcomes. Restenosis is the recurrence of stenosis , a narrowing of a blood vessel , leading to restricted blood flow.
A stent graft or covered stent is type of vascular stent with a fabric coating that creates a contained tube but is expandable like a bare metal stent. Covered stents are used in endovascular surgical procedures such as endovascular aneurysm repair. Stent grafts are also used to treat stenoses in vascular grafts and fistulas used for hemodialysis.
A bioresorbable stent is a tube-like device that is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. It is made from a material that can release a drug to prevent scar tissue growth. It can also restore normal vessel function and avoid long-term complications of metal stents. [1] [2]
Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA), is a minimally invasive endovascular procedure used to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis.
In cases where a significant artery is totally blocked, it may be possible to remove the plaque and use the same hole in the artery to perform an anastomosis. This technique is called endarterectomy and is usually performed at the right coronary system. [26] Re-operations of CABG (another CABG operation after a previous one) pose difficulties.
