The first human cardiac catheterization …

Werner-ForssmannThe first human cardiac catheterization was done by Werner Forssmann who, after failing to get permission from his department chief, anesthetized his arm, inserted a catheter into his vein and threaded it into his heart. He then walked down to the X-ray department and took a picture to prove it. “He ignored his department chief and persuaded a nurse in charge of the sterile supplies to assist him. She agreed, but only on the promise that he would do it on her rather than on himself. However, Forssmann tricked her by restraining her to the operating table and pretending to locally anaesthetise and cut her arm whilst actually doing it on himself.
