MI = myocardial infarction; TVR = target vessel revascularization.

  • By Fisher exact test.

  • Angiographically documented.

  • In a patient with calcified ostium of the left main coronary artery (LMCA), a residual ≈50% stenosis despite use of cutting balloon and rotablator justified elective surgical revascularization.
