Is CTO PCI better than bypass for older patients?
For patients in their 70s and 80s, the trade-offs between complex stenting and open-heart surgery look very different. Here's how we think about it.
For a fit 55-year-old with three-vessel disease and diabetes, coronary artery bypass grafting (CABG) is still often the right long-term answer. For a 78-year-old with the same anatomy, the calculus changes dramatically.
The three things that matter most in older patients
- Recovery time. Bypass surgery typically requires 6–12 weeks of recovery, often including rehabilitation. Complex PCI recovery is measured in days.
- Stroke risk. On-pump bypass carries a small but real stroke risk that rises with age. Radial-access PCI carries essentially none.
- Quality vs quantity of life. Many older patients care more about being independent and pain-free next month than about a marginal survival difference measured over 10 years.
When we still recommend bypass
Left main disease with heavy calcification, poor ventricular function combined with diffuse disease, or anatomy that simply isn't suited to durable stenting — these are still bypass conversations, and we'll say so honestly.
The right question
The question is rarely "PCI or bypass?" in isolation. It's "what does this patient want the next five years to look like?" That conversation is the point of a specialist second opinion.
