Cardiac surgeons performing Norwood operations (a difficult pediatric surgery) show a clear learning curve: mortality rates at high-volume centers (400+ cases/year) are about one-quarter the rates at low-volume centers (under 150 cases/year), demonstrating the critical importance of volume for surgical mastery.
