The authors determined the need for transannular patch enlargement (TAPE) in management of ToF by measuring the ratio between pulmonary annulus size to aortic valve annulus size (GA ratio).  A retrospective analysis of 122 pts who had undergone ToF repair with or without TAPE was performed.  GA ratios were smaller in patients undergoing TAPE.  The GA ratio was a better predictor of TAPE (accuracy 90%) than a traditional method (z-score).
