What is coronary catheterization?
Coronary catheterization is a medical procedure in which a thin, flexible tube is inserted into the arterial system of the patient, usually even if the femoral artery on the upper thigh. The tube or catheter is then brought by arteries to the coronary system of the patient, which consists of arteries and veins responsible for blood flow to the heart and heart. Once they have put the tube into the coronary system, doctors can use it to perform various tests and treatment procedures.
The most common purpose of coronary catheterization is the evaluation of the patient's coronary system for obstacles to the cause of plaque increase along the walls of different blood vessels. In this procedure, the patient lies on a flat table and the doctor brings the catheter to the heart where the dye is injected into the bloodstream. When the dye circulates with blood, the doctor can observe the flow on the X -ray machine to see anywhere where the vessels can narrow due to plaque accumulation. Thji the same procedure can also be used to evaluate other heart -related conditions such as valve function,The size of the heart chambers and the efficiency with which the heart chambers are withdrawing and relaxing.
In addition to the injection of the dye to the coronary system to observe its function, doctors can perform a number of other tests during coronary catheterization. Tests include the ability to monitor blood pressure and flow in certain arteries or heart chambers. They can also be used to measure blood pressure flowing into AZ lungs that cannot be measured separately from the outer body.
The tube used in coronary catheterization can also be used to perform certain procedures. Stents, small metal or plastic tubes can be inserted into blocked or partially blocked blood vessels to restore blood flow. Small balloons can be inserted, inflated in the blood vessel and then released, increases the diameter of blocked or partially blocked blood vessels in the procedure known as angioplasty. Another procedure that can be performed via Katétru, is aterectomy. In this procedure there is a clot or other obstacle and then a small blade or laser is inserted through the catheter to block.
As the technology has advanced, the use and versatility of coronary catheterization increased. Different and improved types of cutting devices such as new types of lasers and rotary shoulder blades have been designed to increase the efficiency and types of procedures that can be performed through a coronary catheter. It has also been progress in the use of devices such as stents covered with a layer of material containing drugs that can prevent or reduce negative reactions in the body, increase the life of the stent and reduce the need for other invasive procedures.
