"Adrian Kantrowitz (October 4, 1918 – November 14, 2008) was an American cardiac surgeon whose team performed the world´s second heart transplant attempt (after Christiaan Barnard) at Maimonides Medical Center in Brooklyn, New York on December 6, 1967. The infant lived for only six hours. At a press conference afterwards, Kantrowitz emphasized that he considered the operation to have been a failure.
Kantrowitz also invented the intra-aortic balloon pump (IABP), a left ventricular assist device (L-VAD), and an early version of the implantable pacemaker." - (en.wikipedia.org 03.12.2019)
