Usefulness of enhanced stent visualization imaging technique in simple and complex PCI cases.

Stent underexpansion and underdeployment are associated with unfavorable outcomes including stent thrombosis, in-stent restenosis, and geographical miss. Visualization of coronary stents is increasingly difficult due to the reduction in stent strut thickness to improve deliverability. The gold standard evaluation method for stent expansion is intravascular ultrasound (IVUS), but its routine use is costly, time-consuming, and not without risk. Enhanced stent visualization is a novel fluoroscopy-based technique that improves visualization of deployed stents in the coronary arteries. We present a case series highlighting the use of this technique in percutaneous coronary intervention.
