Usually, angioplasty is performed in a cardiac catheterization laboratory, this laboratory is called "cat lab". Electrodes will be placed on your chest and you will be connected to a heart monitor to monitor your heart during angioplasty. General anesthesia is not required, but you will be injected with an intravenous sedative. groin
Your thigh (or sometimes arm), where the catheter will be inserted, is trimmed and disinfected, and then numbed with medication. After this part of the body is numbed, you will no longer feel any pain during angioplasty, but at the same time you will be awake and alert.
The doctor finds the right artery and inserts a catheter (a thin tube) through the skin. He sends the catheter through the artery to the aorta and from there to the heart, which can be seen on the monitor. When the catheter is placed in the entrance of the coronary artery, a contrast agent is injected so that the doctor can take pictures of the arteries and detect any narrowing in the blood path of the coronary artery. After checking the size and extent of the obstruction, the doctor may insert a balloon-shaped device into the body and direct it to the location of the obstruction and then inflate the balloon against the walls of the artery. The inflated balloon is kept in the constricted area for two minutes and then deflated. If necessary, the doctor repeats this several times. If the results are satisfactory, the balloon is deflated and the catheter is removed from the body.
