Coronary artery disease
Diseases of the coronary arteries occur when there is narrowing or blockage of coronary arteries caused by arteriosclerosis. The arteriosclerosis is an accumulation of cholesterol and fat deposits on the inner walls of arteries, causing a restriction in the flow of blood to the heart.
When the narrowing of the arteries is important, the blood supply to the heart muscle is decreased and symptoms such as chest pain (angina) or tiredness with small efforts appear. If one of the arteries becomes completely blocked, part of the heart runs out of oxygen and a heart attack occurs.
It consists of x-ray visualization of the coronary arteries, after injection of a radiological contrast through a probe (catheter) that is inserted from an artery in the leg or arm to the start of the coronary arteries, at the exit of the heart . Pressures are taken from the places where the catheter passes, and the movement of the heart as a whole and the functioning of the valves can also be visualized.
Endovascular Surgery (Placement of Stents in the Extremity Arteries)
It is an option for peripheral vascular disease. Through a system of catheters or small tubes that are inserted into the arteries, either to unclog them, or to unclog and place them, what is called “Stent” or “Intraluminal meshes”, which help keep this artery open .
