Background:Percutaneous interventions of coronary bifurcations have always been a difficult challenge, with a lower success and higher complication rate than most other lesion types.
Methods: Fifty patients with symptomatic stable or unstable angina and with bifurcation lesions were treated with Multilink Frontier™ bifurcation-dedicated stent. In-hospital, thirty-day and nine-month follow-up data were
obtained. Repeat coronary angiography was performed only in the case of recurrence of symptomatic ischaemia.
Results: The device was successfully implanted in 46 patients. During 30-day follow-up there were no cases of
death, stent thrombosis or Q-wave myocardial infarction (MI). In-hospital non-Q-wave MI was diagnosed in two patients. During long-term follow-up no patient died, there was one case of Q-wave MI, and five patients (10%) underwent repeat target-lesion revascularization because of restenosis.
Conclusions: Multilink FrontierTM, a stent specifically designed for treating bifurcation lesions can be used with a high procedural success rate, and a satisfactory clinical long-term outcome.
