Scholarcy highlights

  • Lesions involving the left main coronary artery are prognostically relevant
  • An minimum lumen area of 6 mm assessed by intravascular ultrasound has been proposed as a cutoff value to determine lesion severity, but there are no large studies evaluating the prospective application and safety of this approach
  • Consecutive patients with intermediate lesions in unprotected LMCA were evaluated with intravascular ultrasound
  • In the 2-year period, only 8 patients in the deferred group required subsequent LMCA revascularization, none with an infarction
  • An MLA of 6 mm or more is a safe value for deferring revascularization of the LMCA, given the application of the clinical and angiographic inclusion criteria used in this study
  • The authors have reported that they have no relationships to disclose
