[Management of patients with left main stem stenosis in Iceland 2010-2020: PCI or CABG].

Introduction: Coronary artery bypass surgery (CABG) has been standard treatment for patients with left main coronary artery disease (LMCAD) but percutaneous coronary intervention (PCI) can be a good alternative.

We also assessed the impact of patient background factors on treatment choice and long-term survival.
