Coronary artery bypass grafting (CABG) has long been the standard for advanced coronary artery disease. While effective, it is a major operation involving a sternotomy, heart–lung machine use, potential blood transfusion, and weeks of recovery. Many patients today can be treated with less invasive alternatives tailored to their anatomy and risk profile.
Modern drug-eluting stents (DES) can deliver excellent outcomes, especially for focal or limited disease. PCI avoids opening the chest and typically enables rapid recovery.
DCBs deliver anti-restenotic medication into the vessel wall without leaving a permanent implant. Suitable use cases include small vessels, bifurcations, in-stent restenosis, and patients who may need shorter durations of dual antiplatelet therapy.
Selected patients benefit from a combined approach (e.g., minimally invasive LIMA-to-LAD plus PCI elsewhere), balancing durability with reduced surgical trauma.
Summary: Not every patient with coronary disease requires bypass surgery. Careful imaging (angiography plus IVUS/OCT) and individualised planning can identify safer, less invasive options.
Is bypass the only option for blocked arteries?
No. Depending on lesion location, complexity, and overall risk, PCI, DCB, or hybrid strategies may be appropriate.
What is the recovery time for bypass compared with PCI?
Bypass commonly requires weeks to months of recovery. PCI is usually next-day discharge with faster return to normal activity.
Are bypass alternatives suitable for everyone?
Not always. Detailed assessment with intravascular imaging (IVUS/OCT) helps determine the safest and most effective approach. Sometimes bypass is the best approach.
