Complex anatomic situations including tortuosity, calcification, or diffuse atherosclerosis frequently require escalating degrees of backup support. The components of the “backup” support intrinsic to an angioplasty system includes the guide catheter, guidewire(s), and balloon(s) in the target artery. The components can be changed individually or in combination as demanded by the difficulties that are encountered. Hybrid strategies using more complex wire and/or balloon‐based techniques are sometimes required to overcome more challenging anatomies.
