Cardiac catheter, United States, 1950-1970
This catheter is designed to be inserted into the aorta and chambers of the heart by passing it through a vein or artery either in the arm or groin. This procedure can be carried out during an investigation into a possible heart problem or as part of the subsequent treatment. Once situated in the heart it can, for example, be used to measure the pressure of the heart chambers or remove blood samples. The catheter can also be used to inject dye into the arteries and heart when taking an X-ray in order to give the physician a more detailed picture of the heart. This can help in diagnosing heart conditions.
