Coronary Artery Revascularisation : Past, Present and Future.

Area of Science:

• Cardiovascular medicine
• Medical technology
• Interventional cardiology

Background:

• Coronary artery disease (CAD) prevalence necessitates effective revascularization strategies.
• Coronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCI) are primary treatment modalities.
• Innovations in PCI, particularly drug-eluting stents (DES), have improved outcomes but introduced new challenges.

Purpose of the Study:

• To review the limitations of current-generation DES.
• To discuss advancements in coronary stent technology.
• To explore the evolution of CABG techniques and their comparative outcomes with PCI.

Main Methods:

• Literature review of recent technological advancements in CABG and PCI.
• Analysis of safety and efficacy data for DES and evolving CABG procedures.
• Discussion of emerging trends and future directions in coronary revascularization.

Main Results:

• DES have significantly reduced restenosis rates after PCI.
• Late stent thrombosis remains a concern with DES, driving further technological development.
• CABG technology has advanced, including off-pump, minimally invasive, and robotic approaches.
• Adverse outcome differences between CABG and PCI are diminishing.

Conclusions:

• Ongoing innovation in both PCI (stent technology) and CABG is improving patient outcomes.
• The risks associated with DES necessitate continued research and development.
• Future coronary revascularization may involve greater synergy between PCI and CABG approaches.
