The EBC MAIN LM study randomized 467 patients with severe left main coronary artery (LCA) lesions to receive provisional stenting or a two-sent strategy (Resolute or Onix stent). The two-stent strategy was decided by the operator (culotte, DK-minicrush, T/TAP).
The crossover rate from those randomized to provisional stenting was 22%.
After a 3-year follow-up, the composite of death, acute myocardial infarction (AMI), and treated lesion revascularization (TLR) was similar (23% vs. 29%; p = 0.13).
Mortality and AMI rates were similar (10% vs. 13%; p = 0.27, and 12% vs.11%; p = 0.75). TLR rates were lower in patients who received provisional stenting (8% vs. 14%; p = 0.02), and most reinterventions were in the circumflex artery ostium.
