![]() The compatible Dragonfly™ Imaging Catheters are not intended for use in the left main coronary artery or in a target vessel which has undergone a previous bypass procedure. The compatible Dragonfly™ Imaging Catheters are intended for use in vessels 2.0 to 3.5 mm in diameter. The OPTIS™ Imaging System with a compatible Dragonfly™ Imaging Catheter is intended for the imaging of coronary arteries and is indicated in patients who are candidates for transluminal interventional procedures. ![]() Indications The OPTIS™ Software and AptiVue™ E Series Software are intended to be used only with compatible OPTIS™ Imaging Systems.

The next innovation in PCI is not a stent. 5 Stent expansion is linked to better PCI outcomes. ![]() Using OCT with MLD MAX workflow can improve stent expansion 4 without additional contrast while reducing radiation exposure compared to angiography-guided PCI. PCI guidance with OCT is easier now with the development of the standardized step-by-step workflow (also referred to as algorithm), MLD MAX, which is mnemonic for Morphology, Length, Diameter, Medial Dissection, Apposition and Xpansion. 3 OCT helps to confirm that stent is fully expanded to reduce stent failure. ![]() For post-PCI guidance, OCT offers improved visualization of stent dissection, tissue protrusion and incomplete vessel wall apposition compared to angiography alone, thus helping to minimize stent thrombosis.For pre-PCI guidance, OCT can be used to identify the culprit lesion, assess lesion morphology to select the right lesion preparation strategy, and characterize the stent landing zones to select precise length and diameter of balloons and stents. ![]()
