Three-dimensional angiography pre- and post- Left Main treatment

Author: Patrick W. Serruys, MD, PhD, Thoraxcenter, Erasmus Medical Center R&D Department, Cardialysis, Rotterdam, the Netherlands

 

OVERVIEW

  • Part I. Modification of Left Main bifurcation angle by systolic-diastolic motion and by treatment. Preliminary exploratory research prior to official submission to the Steering Committee of the SYNTAX trial.
  • Part II. Long-term follow-up of the Thoraxcenter Left Main population 2000-2005. Impact of the distal bifurcation angle on outcome

CONCLUSION

  • There is a large variation in  the Left Main bifurcation angulation parameters
  • Systolic-diastolic motion affects the bifurcation angulation
  • PCI treatment affects the distal bifurcation angle
  • Endsystolic values of distal BA affect the outcome (MACE) significantly. This is the case both for the entire population as well as for subgroups( DES, distal LM treatment).
  • Enddiastolic values exhibit a strong trend.
  • Further, in-depth analysis, is necessary
