Cure

Cincinnati Children’s researchers Samuel Kaplan, MD, James Helmsworth, MD, and Leland Clark, PhD, developed the first functional heart-lung machine, opening the door to open-heart surgery. Today there are about 500,000 open-heart surgeries performed annually in the U.S. alone — all predicated on this clinical advancement. Thinking that pushes envelopes means parents and their kids can benefit from treatments that extend lives.
