ABSTRACT
In-stent restenosis (ISR) when treated with balloon angioplasty (PTCA) alone, has a angiogrphic recurrence rate of 30%-85%. Ablating the hypertrophic neointimal tissue prior to PTCA is an attractive alternative, yet the late outcomes of such treatment have not been fully determined. This multicenter case control study assessed the angiographic and clinical outcomes of 157 consecutive procedures in 146 patients with ISR at nine institutions treated with either the PTCA alone (n=64)o excrimer laser assisted coronary angioplasty (ELCA, n=93) for ISR. Demographics were similar except more unstable angina at presentation in ELCA-treated patients (74.5% vs 63.5$; P=0.141). Lesions selected for ELCA were longer (16.8 +_ 11.2mm vs. 11.2+_ 8.6 mm;P < 0.001), more complex (ACC/AHA type C35.1% vs. 13.6%;P<0.00001)...
