English to Italian Medical Medical: Cardiology coronagrophy

One of these
doctors was Charles Dotter, a radiologist at
the University
of Oregon. At a conference in Prague in 1963,
Dotter predicted that the angiographic catheter could be
“more than a tool for diagnostic observation. Used with imagination,
it can become an important surgical instrument.”
Dotter—“
Crazy Charlie,” to some—was
an odd bird: a mountain
climber, ornithologist, and amphetamine addict. He fash-
ioned guide wires for his procedures out of guitar string, and
at conferences he blowtorched catheters out of Teflon tubing
at his hotel.
Once, in the middle
of delivering a lecture on cardiac
catheterization, he rolled up his shirtsleeve to reveal to the
audience that he had placed a catheter in his own heart that
morning. Then, as he continued to lecture, he connected himself
to an oscilloscope to record the pressures from his cardiac
chambers.
