[Correspondence] Stents versus bypass surgery for left main stem stenosis

The recent Article by Timo Mäkikallio and colleagues (Dec 3, p 2743)1 reported the eagerly awaited 5-year results of the NOBLE trial, comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) for the treatment of unprotected left main stem stenosis. The authors concluded that CABG might be preferred to PCI, because of the lower risk of non-procedural myocardial infarction and repeat revascularisation, despite a higher rate of reoperation within 30 days and similar mortality between the two groups.
