Insights
Redo coronary artery bypass grafting (CABG) offers good outcomes but has higher immediate mortality than percutaneous coronary intervention (PCI). Long-term survival is similar, but further research is needed for redo CABG
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
Background:
- Percutaneous coronary intervention (PCI) has advanced significantly.
- Redo coronary artery bypass grafting (CABG) is a complex procedure for patients with prior CABG.
Purpose of the Study:
- To review the evidence for redo CABG in the context of current PCI practices.
- To evaluate the role and relevance of redo CABG in contemporary cardiovascular revascularization.
Main Methods:
- A comprehensive electronic literature search was conducted.
- Relevant studies on PCI and redo CABG were identified and summarized narratively.
Main Results:
- PCI advancements have decreased the rate of redo CABG.
- Redo CABG shows satisfactory perioperative outcomes but higher immediate postoperative mortality compared to PCI.
- Redo CABG patients have fewer revascularization-associated comorbidities but similar long-term survival to PCI.
Conclusions:
- Redo CABG has higher operative mortality than PCI, though long-term survival is comparable.
- Further research is required to define the precise role of redo CABG amidst advanced PCI techniques.
Objective:
To review the evidence behind the role and relevance of redo coronary artery bypass grafting (CABG) in the current practice of percutaneous coronary intervention (PCI).
Methods:
A comprehensive electronic literature search was performed to identify articles that discuss the practice of PCI and redo CABG in patients that require coronary revascularization. All relevant studies are summarized in narrative manner to reflect current indications and preference.
Results:
The advancement in utilization of PCI has reduced the rate of redo CABG in patients with previous CABG that requires revascularization of an already treated coronary disease or a new onset of coronary artery stenosis. Redo CABG is associated with satisfactory perioperative outcomes but higher mortality at immediate postoperative period when compared to PCI.
Conclusion:
Redo CABG patients are less likely to develop comorbidities associated with revascularisation, but the operative mortality is higher and long-term survival rates are similar in comparison to PCI. There is a need for further research into the role of redo CABG in the current advanced practice of PCI.
