With this procedure, we examine how well your heart is working. A thin, hollow tube called a catheter is inserted into a large blood vessel that leads to your heart.
During the procedure, the pressure and blood flow in your heart can be measured.
Coronary angiography is done during cardiac catheterization. A contrast dye visible in X-rays is injected through the catheter. X-Ray images show the dye as it flows through the heart arteries. This shows where arteries are blocked.
Why do patient have cardiac catheterization?
A cardiac cath provides information on how well your heart works, identifies problems and allows for procedures to open blocked arteries.
During cardiac cath your doctor may:
- Take X-rays using contrast dye injected through the catheter to look for narrowed or blocked coronary arteries, known as coronary angiography or coronary arteriography.
- Perform a percutaneous coronary intervention (PCI) such as coronary angioplasty with stenting to open up narrowed or blocked segments of a coronary artery.
- Check the pressure in the four chambers of your heart.
- Take samples of blood to measure the oxygen content in the four chambers of your heart.
- Evaluate the ability of the pumping chambers to contract.
- Look for defects in the valves or chambers of your heart.
- Remove a small piece of heart tissue to examine under a microscope (biopsy).
