Insights
Achieving complete revascularization in multivessel coronary artery disease is crucial. While coronary artery bypass grafting often achieves this, percutaneous coronary intervention faces challenges, making complete revascularization the preferred goal.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Multivessel coronary artery disease (CAD) treatment decisions are complex.
- Factors influencing treatment include clinical status, comorbidities like diabetes mellitus, and coronary anatomy.
- Coronary artery bypass grafting (CABG) has historically aimed for complete anatomical revascularization.
Purpose of the Study:
- To discuss the challenges and importance of complete revascularization in multivessel CAD.
- To compare the feasibility of complete revascularization between CABG and percutaneous coronary intervention (PCI).
- To emphasize complete revascularization as a therapeutic goal.
Main Methods:
- Review of current clinical practices and emerging data on revascularization strategies.
- Analysis of the comparative effectiveness of CABG versus PCI in achieving complete revascularization.
- Discussion of anatomical and clinical factors impacting revascularization success.
Main Results:
- Complete revascularization is more consistently achieved with CABG compared to PCI.
- Incomplete revascularization is more common with PCI.
- Emerging data suggest significant clinical outcome benefits associated with complete revascularization.
Conclusions:
- Complete anatomical revascularization should be the goal in treating multivessel CAD whenever feasible.
- The heart team must carefully consider revascularization modality capabilities during procedural planning.
- Optimizing revascularization strategies is essential for improved patient outcomes.
Opinion Statement:
The treatment of patients with multivessel coronary artery disease in need of a revascularization procedure is influenced by the clinical situation (stable vs. unstable), comorbid conditions (diabetes mellitus), and anatomical variables (proximal left anterior artery stenosis, left ventricular dysfunction). Given the invasive nature of coronary artery bypass graft (CABG) operations, surgeons have embraced the concept of complete anatomical revascularization in one procedural stage since the inception of CABG surgery. However, achieving complete coronary revascularization has been more challenging with percutaneous coronary intervention (PCI), and as a result, incomplete procedures are far more common than complete ones. Data continue to emerge on the potential benefits of complete revascularization on clinical outcomes and suggest that complete revascularization should be the goal of therapy whenever possible. The heart team should carefully review the degree to which each revascularization modality can achieve this goal during procedural planning.
