Princeton Medical Center's fully digital cardiac catheterization laboratory is dedicated to providing prompt and accurate diagnosis of heart problems such as muscle or structural defects and clogged blood vessels. The use of digital imaging ensures the capture of high quality images while dramatically reducing the amount of radiation exposure. The catheter is a long, flexible tube that is gently guided through your blood vessels toward your heart. Once in place, x-rays and other tests are performed to help your physician evaluate how well your heart is working. Cardiac catheterizations at Princeton Medical Center are performed by board certified cardiologists, who are assisted by skilled technical and nursing personnel.
