Reverse curve catheters facilitate catheterization of vessels angled oppositely from the point of access. Most commonly, they are used to access caudally angulated vessels from a femoral approach. An array of these catheters exists, and their utilization greatly expands the options for intervention from any single access. Once formed, the catheters are gently advanced forward until their tip engages the vessel of interest, typically confirmed with an injection of contrast under live fluoroscopy. Engagement of the vessel is then performed by advancing a guidewire into the vessel of interest and retracting the catheter to seat the tip more distally within the vessel, providing a stable access. This chapter reviews four techniques for forming large reverse curve catheters.
