What is the gold standard for a left main intervention?

• A. CABG
• B. PCI with bare-metal stents
• C. Medical therapy
• D. Valve replacement

Answer: (A)

CABG is the preferred approach for left main disease because it provides durable, complete revascularization of the affected coronary territory. By bypassing the diseased left main and revascularizing the downstream vessels as needed, CABG offers better long-term survival and reduces the need for repeat revascularization, especially in patients with complex multivessel disease or diabetes. While PCI with drug-eluting stents is an option in carefully selected patients with favorable anatomy and in experienced centers, the longstanding standard of care for definitive left main revascularization has been surgical bypass. Medical therapy alone does not address the blocked pathway, and valve replacement does not treat the left main lesion. Bare-metal stents historically performed worse than CABG for left main disease, reinforcing why CABG remains the gold standard.
