N2 - BACKGROUND: Administration of a large amount of contrast volume during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) may lead to contrast-induced nephropathy. METHODS: We examined the association of clinical, angiographic and procedural variables with contrast volume administered during 1330 CTO-PCI procedures performed at 12 experienced United States centers. RESULTS: Technical and procedural success was 90% and 88%, respectively, and mean contrast volume was 289 ± 138 mL. Approximately 33% of patients received >320 mL of contrast (high contrast utilization group). On univariable analysis, male gender (P≤.01), smoking (P≤.01), prior coronary artery bypass graft surgery (P≤.04), moderate or severe calcification (P≤.01), moderate or severe tortuosity (P≤.04), proximal cap ambiguity (P≤.01), distal cap at a bifurcation (P<.001), side branch at the proximal cap (P<.001), blunt/no stump (P≤.01), occlusion length (P<.001), higher J-CTO score (P≤.02), use of antegrade dissection and reentry or retrograde approach (P<.001), ad hoc CTO-PCI (P≤.04), dual arterial access (P<.001), and 8 Fr guide catheters (P<.001) were associated with higher contrast volume; conversely, diabetes mellitus (P≤.01) and in-stent restenosis (P≤.01) were associated with lower contrast volume. On multivariable analysis, moderate/severe calcification (P≤.04), distal cap at a bifurcation (P<.001), ad hoc CTO-PCI (P<.001), dual arterial access (P≤.01), 8 Fr guide catheters (P≤.02), and use of antegrade dissection/reentry or the retrograde approach (P<.001) were independently associated with higher contrast use, whereas diabetes (P≤.02), larger target vessel diameter (P≤.03), and presence of interventional collaterals (P<.001) were associated with lower contrast utilization. CONCLUSIONS: Several baseline clinical, angiographic, and procedural characteristics are associated with higher contrast volume administration during CTO-PCI.
