A coronary angiogram is a surgical procedure done to assess the coronary arteries for blockages. This is carried out if one’s stress test indicates a significant arterial blockage. During the angiogram, a tiny thin tube is inserted in an artery or vein in the groin and threaded through the vessels to look for blockages near the heart. A type of dye that's visible by X-ray machine is injected into the blood vessels of the heart. This allows for a detailed look at the inside of the coronary blood vessels. If a blockage is found during cardiac catheterization, the doctor removes plaques from the arteries and places a small mesh wire called a stent that keeps the cleared artery open. Should it be necessary for you to get an coronary angiogram or cardiac stent placement, our highly respected interventional cardiologist can follow through with you at New York Methodist Hospital in Park Slope, Brooklyn or Wyckoff Heights Medical Center in Bushwick, Brooklyn.
