Abstract

PURPOSE:The purpose of this study is to assess the immediate outcome and long-term results of high pressure bail-out coronary stenting without subsequent anticoagulation. PATIENTS AND METHODS: Between June 1994 and September 1996, 32 consecutive patients (males 24, mean age 55 +/- 9.3 years) underwent bail-out stenting at a mean deployment pressure of 15.5 +/- 2.3 mmHg because of complicated PTCA. A total of 54 stents (Palmaz-Schatz, Micro, Gianturco Roubin and Wiktor) were implanted, from one to four stents into each vessel. After the procedure all patients were treated with ticlopidine 500 mg/day and acetylosalicylic acid 300 mg/day only. RESULTS: Stents were successfully delivered in all patients. In the cath lab procedural success was 96.9%. During the in-hospital phase, there was one (3.1%) acute stent thrombosis followed by urgent bypass surgery (CABG). Four (12.5%) non-Q wave myocardial infarctions occurred. There were no subacute stent thrombosis or hemorrhagic complications. Six month angiographic restudy in 28 patients showed restenosis in 13 (46.4%): 9 patients were treated successfully by rePTCA. At one year 13 (40.6%) major adverse cardiac events occurred: eleven (34.4%) target lesion revascularizations (9 PTCA, 2 CABG), one (3.1%) elective CABG surgery and one (3.1%) late cardiac death. Event-free survival was 93.8% at one month, 65.6% at six months, and 59.4% at one year. CONCLUSIONS: High pressure bail-out coronary stenting with antiplatelet regimen is an effective and safe procedure for treating complicated PTCA. Although the restenosis rate is high, in most cases in-stent restenosis can be treated by rePTCA. In 60% of patients clinical course at one year was uneventful.
