A newborn diagnosed with a severe congenital heart defect has been given a new lease on life following a high-risk surgical procedure at Fuwai Yunnan Cardiovascular Hospital in Kunming, Yunnan Province. The infant, weighing a mere 2.9 kilograms at birth, was found to have transposition of the great arteries (TGA), a rare condition where the heart’s two main arteries are reversed, severely impairing blood circulation and oxygen supply. Shortly after birth, the baby exhibited critically low blood oxygen levels, exacerbated by the near-closure of the foramen ovale, a vital passage for blood flow in newborns. A multidisciplinary medical team, led by Wang Xiaoqi, the hospital’s vice-president, and Dong Shuo, director of pediatric surgery, performed an arterial switch operation to correct the defect. Four days post-surgery, the infant was successfully weaned off the ventilator and showed signs of steady recovery. The baby has since been moved from intensive care to a general ward and is expected to be discharged soon. ‘This was an exceptionally high-risk procedure for a one-day-old baby weighing less than three kilograms,’ Wang remarked. ‘However, the team’s precision and collaboration ensured a successful outcome.’
