Impact of routine angiographic follow-up after percutaneous coronary drug-eluting stenting for unprotected left main disease: the Turin Registry

Background Most cardiologists performing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for unprotected left main disease (ULM) mandate mid-term angiographic follow-up, yet there are few data supporting this approach. We aimed to retrospectively compare the outcome of patients with ULM treated with DES according to their follow-up management strategy.
