The Spanish Registry of Chronic Total Occlusion Secondary to an Occlusive In-Stent Restenosis evaluated results and clinical outcomes in patients undergoing percutaneous intervention for chronic total occlusion due to in-stent restenosis.
Design: Retrospective, registry
Results: A successful acute result occurred in 82.4% of patients, but was less likely to occur in patients with a lesion in the circumflex artery, an ostial lesion, a J score > 3 or no femoral access. Presence of tandem lesions predicted procedure success (OR = 0.19; 95% CI, 0.06-0.68). During median follow-up of 20 months, cardiac death occurred in 3% of those with a successful procedure and 8.3% of those with a failed one (P = .09). Independent predictors of mortality were previous CABG (HR = 8; 95% CI, 1.3-50) and multivessel disease (HR = 2.3; 95% CI, 1.2-4.3).
