Get Directions

Bradford Regional Medical Center (BRMC) offers a broad array of diagnostic capabilities for cardiac patients, including stress testing, nuclear imaging, Diagnostic Coronary angiography, and echocardiography. BRMC also offers pediatric cardiac services.

BRMC  offers patients a cardiac catheterization program under the direction of  board-certified cardiologist Christopher T. Mallavarapu, MD, FACC, FSCAI. This program allows patients to receive diagnostic cardiac catheterization procedures right at BRMC instead of having to travel outside the area.

Cardiac Stress Lab

A stress test is used to provide information about how well the heart works during physical activity. Because exercise makes the heart pump faster and harder, a stress test can reveal problems within the heart that might not be noticeable otherwise.

At the Bradford Regional Medical Center’s Stress Lab, we provide many types of cardiac stress testing. Your doctor may recommend an exercise stress test if he/she suspects you have an irregular heart rhythm (arrhythmia) or coronary artery disease. If you already have been diagnosed with a heart condition an exercise stress test may also be used to guide your treatment.

Diagnostic Coronary Angiography

What is Angiography?

Angiography is a common diagnostic test used to measure the flow and pressure of blood in the chambers of the heart and determines if the arteries that supply blood and oxygen to the heart muscle are blocked or narrowed.  Through angiography, also known as diagnostic cardiac catheterization, doctors can diagnose blood vessel damage around the heart.  The test is performed in the cardiac catheterization lab and takes about 45 minutes.

How is Angiography Performed?

A long, thin, flexible tube called a catheter is threaded into a blood vessel in the arm, groin (upper thigh), or neck and threaded to the heart. During angiography, dye is injected through the veins and/or into the heart's chambers. (animation – click here)

This procedure causes areas where blood flows to temporarily darken and create a contrast with surrounding tissue to ensure that images can be created with X-rays (called an angiogram). The movement of the dye through the heart and coronary arteries is recorded as an angiogram and viewed on a television monitor,  

What to Expect

Many patients experience a warm sensation throughout their body when the dye is injected. Sometimes the patient is asked to cough vigorously.

If any chest discomfort is experienced during the test, the medical team should be alerted. The procedure may take one to two hours, but preparation and recovery will take an additional two to four hours.

Is Angiography Safe?

Angiography is a safe test and the dye used will cause no harm. Patients should drink plenty of water following the procedure to help rid the body of the dye.

In rare cases, some people may have an allergic reaction to the dye. Tell the doctor before the test of any allergies to iodine, shellfish or strawberries.

Procedure Options

Angiography procedures can be performed through the wrist (radial approach) or the more traditional groin (femoral approach) method. Radial angiography allows patients increased mobility after the procedure with a lower risk of bleeding and other complications. Patients can be discharged about two hours after a diagnostic procedure and can ambulate within minutes after a radial angiogram.
