N2 - BACKGROUND: Intravascular ultrasound (IVUS) can assist percutaneous coronary intervention (PCI) of chronic total occlusions (CTO). METHODS: We analyzed 8,983 CTO PCIs performed in 8,771 patients between 2012 and 2022 at 39 centers. RESULTS: Overall, IVUS was used in 44.5% of the cases, for crossing in 11.5% and for stent optimization in 33.1%. IVUS for stent optimization was used more often for complex lesions with higher prevalence of calcification (51.2% vs 34.3%; P <.001); was associated with lower air kerma radiation dose (1.78 [1.00, 3.09] vs 2.30 (1.35, 3.91) min, P<.001) and contrast volume (190 [138, 258] vs 220 [160, 300] ml, P <.001). Among cases with successful guidewire crossing, those that used IVUS for stent optimization had higher technical (99.3% vs 96.3%; P <.001) and procedural (96.1% vs 94.6%, P =.002) success rates and similar major adverse complication event rates (2.04% vs 1.62%; P =.176). The use of IVUS for stent optimization significantly increased over time. CONCLUSION: In a contemporary, multicenter registry, IVUS was used in 44.5% and its use for stent optimization significantly increased over time. Cases where IVUS was used for stent optimization had higher technical and procedural success and similar risk of complications compared with cases where IVUS was not used for stent optimization.
