Catheter placement during a cardiac catheterization

Catheter insertion points at neck, wrist, and groin, showing catheter placed in right side of heart or in left side.

Cardiac catheterization is done using a thin, soft tube called a catheter. A doctor inserts the catheter into a blood vessel, often in the wrist, groin, or neck, using a special needle. The doctor then slowly guides the catheter through blood vessels toward the heart. The catheter may be moved into the left side or right side of the heart. The catheter tip is moved into various positions in the heart's chambers and vessels (coronary arteries).
