Insights

Hybrid coronary revascularization (HCR) outcomes are similar regardless of whether coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) is performed first. This study found no significant differences in clinical outcomes between the two approaches.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology

Background:

  • Hybrid coronary revascularization (HCR) combines coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI).
  • Optimal sequencing of CABG and PCI within HCR remains debated.
  • This study compares clinical outcomes based on the initial procedure in HCR.

Purpose of the Study:

  • To compare clinical outcomes of CABG-first versus PCI-first approaches in HCR.
  • To evaluate the safety and efficacy of different HCR procedural sequences.

Main Methods:

  • Retrospective analysis of 80 patients undergoing HCR (May 2010-Dec 2015).
  • Groups: CABG-first (12 patients) and PCI-first (68 patients).
  • Outcomes assessed: perioperative factors, major adverse cardiac and cerebrovascular events (MACCEs), and repeat revascularization.

Main Results:

  • No significant difference in postoperative bleeding between groups.
  • Similar incidence of MACCEs: 8.3% (CABG-first) vs. 7.4% (PCI-first).
  • Repeat revascularization rates were 25% (CABG-first) vs. 13.2% (PCI-first), not statistically significant.

Conclusions:

  • No significant differences in postoperative or medium-term outcomes between CABG-first and PCI-first HCR.
  • Either CABG or PCI can be safely chosen as the primary procedure in staged HCR.
