The backup force of a guiding catheter is important for successful percutaneous coronary intervention (PCI), however, no theory has been proposed thus far regarding the factors involved in its generation.
METHODS AND RESULTS: The backup force of guiding catheters was measured in an arterial tree model. In vitro modeling showed that larger-sized guiding catheters had greater backup force (8 Fr > 7 Fr > 6 Fr). Comparing the backup force between transfemoral (TFI) and transradial interventions (TRI), it was found to be 60% greater in TFI with a Judkins L (JL) catheter, and 8% greater in TFI with a backup (EBU/XB) type catheter.
