On Monday night Jimmy Kimmel held back tears as he told the story of his new son William's birth. Although the birth in late April went smoothly for both the mother and child, hours after delivery a nurse noted the slightly purple coloring of Kimmel's son, whom they call Billy. After running a few medical tests, doctors and nurses determined that the newborn had a severe heart defect -- Kimmel identified the syndrome as "Tetralogy of Fallot with pulmonary atresia" when he spoke about it Monday. Kimmel's son is now in good health, but the incident led him to make a personal pitch for continued funding to the National Institute of Health (NIH) and health insurance coverage for people with pre-existing conditions, a clause that was established as part of the Affordable Care Act.
