The main outcome was target lesion failure (TLF), defined as the composite of clinically driven target lesion revascularization (TLR), target lesion myocardial infarction (MI), and target lesion\u2010related cardiac death. Cox proportional hazards analysis was performed to identify variables associated with recurrent TLF.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the study period, 116 patients (143 lesions) underwent VBT. Median follow\u2010up was 24.7 (14.5\u201335.4) months. The incidence of TLR, target\u2010lesion MI, and TLF was 18.9%, 5.6%,and 20.1% at 1\u2009year, and 29.4%, 10.5%, and 32.9% at 2\u2009years.Initial presentation with acute coronary syndrome (ACS) was independently associated with TLF (hazard ratio = 1.975, 95% CI [1.120, 3.485], <jats:italic>p<\/jats:italic> = .019). Lesions treated with intravascular ultrasound (IVUS) guidance had a lower incidence of TLR (14.3% vs. 39.6%, log\u2010rank <jats:italic>p<\/jats:italic> = .038), and a trend toward lower incidence of TLF (19% vs. 42.6%, log\u2010rank <jats:italic>p<\/jats:italic> = .086).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>VBT can improve the treatment of recurrent DES\u2010ISR, but TLF occurs in approximately one in three patients at 2\u2009years.
