Catherization Laboratory Department

Cath Lab

The Cardiac Catheterization Lab, or Cath Lab, is a special room housing tools that are highly effective in processing images of coronary blood vessels. An image of the patient’s blood vessels image will appear on a monitor screen and will be recorded as a digital video recording. Digital recording systems can be rotated and inspected repeatedly, allowing doctors to quickly and clearly obtain images from every angle required.

Cardiac catheterization is an extremely useful diagnostic tool. Examinations can be performed to determine the abnormal position of blood vessels, determine the severity of coronary artery disease, see abnormalities of the heart valve, and measure contraction of the heart muscle. If abnormalities of coronary arteries are detected, medical specialists will be able to treat them by adding balloon and/or stent extensions to the catheter.

How an examination is performed

The doctor administers a local anesthetic at the wrist points of entry then puts a small sterile plastic tube into the artery to the heart and go straight to the exit of the artery. After this, the doctor injects a dye through this tube and takes pictures of the blood vessels and heart using a special X-ray box. When examining the coronary artery and injecting dye, the doctor can continue treatment from the original position without the need for additional incisions or invasive surgery. The doctor can insert a navigation wire, place the navigation line in the blood vessel to get to the position of the constricted blood vessel then expand it with a balloon or stent. Doctors advise patients to undergo cardiac catheterization following computerized x-ray diagnosis, heart graphing, blood tests, ECG, running belt and heart ultrasound. Diagnosis of severe stenosis or ineffective drug treatment can indicate coronary artery disease. Finally, a diagnosis is made with a coronary artery examination in order to plan an effective treatment process.
