"Catheter Hole Support": A Novel Technique for Increasing Guide Catheter Support.

Percutaneous coronary interventions (PCI) in the setting of tortuosity, calcification, and some types of coronary takeoffs can be challenging. In such cases, the choice of strategies that promote optimal catheter support is essential for the success of the procedure, by facilitating the delivery of the equipment. We have developed a new support technique: "Catheter Hole Support Technique" is a simple, low-cost, and widely available technique that effectively increases catheter support and system stability.
