Last night, Comedian and Television Host Jimmy Kimmel gave a heartfelt, emotional opening monologue detailing his newborn son Billy's emergency surgery to correct defects in his heart. A few hours after his birth, a nurse noticed a murmur in Billy's heart. Kimmel noted that the hospital team started doing some tests to see whether it might just be fluid in the lungs. Doctors then pivoted to his heart, and performed an echocardiogram that found Billy was born with a heart defect called tetralogy of Fallot with pulmonary atresia. Kimmel recounted the events leading up to and after the surgery.
