BACKGROUND & AIM • The promising role of drug-eluting stents (DES) for percutaneous revascularization of unprotected left main (ULM) has been reported in several settings, including the randomized SYNTAX trial. • However no detailed data are available on subsequent restenosis. • We thus aimed to appraise the incidence and management of restenosis following DES implantation for ULM disease.
METHODS • From the total sample of patients with ULM treated with DES, we identified those presenting with angiographic ULM restenosis. • The primary end-point was the long-term rate of major adverse cardiac events (MACE), ie death, myocardial infarction (MI) or target lesion revascularization (TLR). We also adjudicated stent thrombosis according to the Academic Research Consortium.

STUDY FLOWCHART *5.1% (2.5% dying suddenly) *
CLINICAL OUTCOMES All p>0.05 % Cumulative events after >35 months In-hospital
CONCLUSIONS • Significant ULM DES restenosis is characterized by a stable clinical condition in most patients, even if a subset of them can present with an acute coronary syndrome. • After more than 24 months of clinical follow-up from the diagnosis of restenosis, MACE rates appear quite favorable in both the interventional and surgical therapy groups.
