Cardiac Catheterization Referrals

What is cardiac catheterization?

Cardiac catheterization is a minimally-invasive procedure that can be used to diagnosis an array of heart-related issues and determine the cause of some types of chest pain. Catheterization also can be used to perform an interventional procedure called angioplasty, which uses special techniques to compress or break apart sticky plaque that may be blocking or narrowing arteries. Angioplasty may be performed to avoid the need for more invasive procedures like cardiac bypass surgery.

How is cardiac catheterization performed?

Cardiac catheterization uses a catheter – a very slim, flexible tube – to deliver dye to the area where a blockage is suspected or directly to the area near the heart to evaluate blood flow and heart function. The catheter is inserted through a small puncture incision made in the groin, armpit, or neck. After inserting the catheter, imaging technology is used to monitor the catheter as it is gently advanced to the treatment site. Once in place, a special dye can be injected to highlight the arteries around the heart and to monitor circulation in these vessels. The dye can also show areas of blockage or narrowing that may be causing chest pain. When angioplasty is being performed, the catheter can be used to deliver special instruments to compress sticky plaques, followed by a supportive meshwork called a stent, which helps hold the artery open. After the procedure is complete, a special pressure bandage will be applied to the area. Patients will need to lie still for a few hours to enable a clot to form at the incision site. Activities including driving will be restricted during the initial healing period.

Can I go home the same day I have my procedure?

Most patients who have a cardiac catheterization can be discharged the same day as the procedure. Patients spend a few hours in recovery to enable the puncture site to begin the healing process. If an angioplasty is performed, an overnight hospital stay may be required.
