Peak subepicardial twist was strongly related to infarct size ( number of segments with transmural scar : r ( 2 ) = 0.526 , P < .001 ; total scar score : r ( 2 ) = 0.515 , P < .001 ) compared with peak subendocardial twist ( number of segments with transmural scar : r ( 2 ) = 0.379 , P < .001 ; total scar score : r ( 2 ) = 0.331 , P < .001 ) .
