Learning Curve for Aortic Root Replacement.

ABSTRACT:

Background

The objective of this study was to assess the number of root procedures performed for a newly graduated surgeon to overcome the learning curve.

Methods

An institutional database was used to obtain details for patients undergoing root surgery during a 10-year period for a newly graduated surgeon. To assess learning curve, strucchange R package (engineering method to objectively identify structural changes in data) was used to analyze operative efficiency. A cumulative sum failure analysis curve was plotted to indicate the magnitude and direction of changes in efficiency for this single surgeon. A composite of adverse outcome was assessed across learning curve phases.

Results

Strucchange identified 3 segments to the learning curve. These occurred at 38 (95% C
