Coronary angioplasty is a procedure performed to open coronary arteries of the heart, arteries, which are blocked or narrowed. The intervention improves the circulation of blood to the heart muscle or heart muscle.
With the passage of time, a fatty substance called plaque can build up in the arteries and cause them to harden and narrow. This condition is called atherosclerosis. Atherosclerosis can affect any artery in the body. When it affects the coronary arteries, cause coronary heart disease or coronary artery disease.
Angioplasty can restore blood flow to the heart if the coronary arteries are narrowed or blocked due to coronary heart disease.
Angioplasty is a common medical intervention. It can be performed to accomplish the following:
– Improve symptoms of CHD, as angina and shortness of breath. (Angina is pain or discomfort in the chest).
– Reduce the damage to the heart muscle in heart attack. A heart attack occurs if the flow of a coronary artery is completely blocked. The lock should generally to a blood clot that forms on the surface of the plate. During angioplasty, a balloon within the coronary artery is then inflated to clear the blockage.
– Reduce the risk of death in some patients.
As embodied? This catheter is introduced, and cardiac catheterization, to reach the affected area. In this place a small balloon is inflated to dilate the artery from within.
In most cases places a STENT:
Stents are metal devices of various designs which are introduced into the coronary arteries and their wall propping act. Thus sudden closing or occlusion of the artery is prevented after.
How is a stent implanted?
Through angioplasty performed without general anesthesia. Angioplasty involves inserting a balloon into the femoral artery through a puncture in the groin and guided him to the heart by X-ray. Inflating the balloon, dilates the narrowed area and the blood flows normally. After making balloon inflation, coloca if a coronary stent. In most cases, the patient is discharged from the 24 and 48 hours after the procedure.
