Effect of Intravascular Ultrasound Findings on Long-Term Repeat Revascularization in Patients Undergoing Drug-Eluting Stent Implantation for Severe Unprotected Left Main Bifurcation Narrowing

We studied the effect of the preprocedural intravascular ultrasound findings on stent expansion and the pre- and postprocedural findings on the long-term clinical outcomes in patients undergoing drug-eluting stent implantation for unprotected left main bifurcation disease

Scholarcy highlights

  • We studied the effect of the preprocedural intravascular ultrasound findings on stent expansion and the pre- and postprocedural findings on the long-term clinical outcomes in patients undergoing drug-eluting stent implantation for unprotected left main bifurcation disease
  • Using a left anterior descending pullback, we evaluated the ostial LAD artery, the polygon of confluence, and the distal LM artery
  • In 168 LM bifurcations, the preprocedural minimum lumen area and post-stenting minimum stent area within the LM artery were located within the POC in 41% and 70%, respectively
  • Independent predictors for the post-stent minimum stent area within the distal portion of LM artery above the LAD carina were the preprocedural lumen area of the LAD carina and preprocedural MLA within the POC
  • As assessed by the LAD pullback, the preprocedural MLA within the POC was a surrogate reflecting the overall severity of LM bifurcation disease, contributed to the post-stent minimum stent area within the distal segment of LM bifurcation, and was a predictor of clinical events during follow-up
