1 Influence of experience and the surgical learning curve on long-term patient outcomes in cardiac surgery  Bryan M. Burt, MD, Andrew W. ElBardissi, MD, MPH, Robert S. Huckman, PhD, Lawrence H. Cohn, MD, Marisa W. Cevasco, MD, James D. Rawn, MD, Sary F. Aranki, MD, John G.

2 Figure 1 A, Risk-adjusted cardiopulmonary bypass (CPB) time (in minutes) with respect to years of surgical experience for each procedure. All experience curves have P < .001. B, Best-fit CPB models are shown with R2 values adjusted for patient risk and surgeon-level fixed effects (blue), and additionally adjusted for surgeon experience (red). MVR, Mitral valve replacement; AVR, aortic valve replacement; MV, mitral valve; CABG, coronary artery bypass grafting.
