Our Cardiac Cath Lab operates 24/7, performing diagnostic procedures to determine the extent of disease in the vascular system. If narrowed blood vessels are diagnosed or if other diagnostic tests are inconclusive, cardiac catheterization might be necessary.
Diagnostic Procedures and Devices
After local anesthesia is injected into the skin to numb the area, a long, thin tube, or catheter, is inserted through an artery or vein in the leg or arm, and then into the heart, allowing the physician access to the heart to perform procedures.
A dye that can be seen by an X-ray is injected into a vein or artery. X-rays are then taken to identify blockage of blood supply to the heart muscle.
Fractional Flow Reserve (FFR)
A specialized catheter containing a Doppler wire is inserted into a coronary artery to measure blood flow in that artery beyond a plaque blockage.
A special cardiac catheter is used to obtain tissue samples directly from the heart muscle.
Intracoronary/Intravascular Ultrasound (IVUS)
A small catheter is inserted into the coronary arteries to obtain ultrasound images of blood vessels.
A transesophageal echocardiogram uses sound wave (ultrasound) technology to examine heart function. By inserting a probe with a transducer down the esophagus rather than placing the transducer on the chest, physicians get a clearer image of the heart because the sound waves do not have to pass through skin, muscle, or bone tissue.
