Cardiac Catheterization
The catheter aims to treat vascular diseases, especially the coronary arteries that feed and supply the heart muscle with blood. In order for it to function properly, the catheterization is necessary for the person when a blockage occurs in a blood vessel resulting from atherosclerosis. As a result of the accumulation of fat in the wall of blood vessels, and thus cause a blockage in the arteries of the body, and the goal of the process of cardiac catheterization reduce the pain caused by angina, in case of a major blockage, this affects and causes damage to the heart muscle, sometimes performed catheterization In the heart if there is a defect of the congenital heart, the heart Fix this defect.
Preparation of cardiac catheterization
Before performing the catheterization procedure, the patient performs several tests, such as coagulation, blood chemistry, liver and kidney functions, echocardiography, to detect a heart problem. The procedure is performed under local anesthesia. The patient must refrain from eating before the operation About eight hours.
The process of cardiac catheterization
First, the place of entry into the blood vessels, usually from the caudal artery, or femoral artery, is then determined by the insertion of a thin, long tube (catheter) into a blood vessel. The tube is passed until it reaches The coronary arteries are made by means of a small camera. A dye is injected into the vessels to identify the correct path of the tube. The locations of the blood flow are shown incorrectly on the chassis. Treatment options during the catheterization process include: expansion of the blood vessels, By a small balloon being blown into the blood vessels, or by introducing a retina (Stent) This is a small metal spiral, which helps blood vessels stay open, and at the end of the catheter to the heart, is directed by the catheter tube, and then sew incision, and put the bandage on it.
Risks of heart catheterization
- Infection in the surgical incision.
- Bleeding.
- The risk of anesthesia.
- Sensitivity of dye.
