Key Clinical Takeaways
  • For multi-vessel disease and diabetic patients, CABG offers substantially higher 10-year survival rates than stenting.
  • Off-pump (beating heart) techniques eliminate the heart-lung bypass machine, cutting stroke risk and systemic inflammation.
  • Keyhole / mini-thoracotomy incisions spare the breastbone (sternum), reducing recovery from 3 months to 2–3 weeks.
  • Internal mammary artery grafts deliver 90%+ patency after two decades.
When diagnostic angiograms reveal severe triple-vessel coronary artery disease or left main stem stenosis, patients often face a critical dilemma: multiple drug-eluting stents (PCI) or coronary artery bypass grafting (CABG). Understanding the durability, recurrence rates, and modern off-pump surgical techniques is essential for an informed decision.

Durability: Why Arterial Grafts Outperform Multiple Stents

While percutaneous coronary intervention (PCI) with stents is attractive due to its non-surgical nature, placing 4 or 5 stents in tortuous or calcified vessels carries an ongoing risk of in-stent restenosis and repeat revascularization. Landmark SYNTAX trials have consistently proven that surgical bypass using the left internal mammary artery (LIMA) offers superior long-term freedom from major cardiac events.

Beating Heart Surgery (Off-Pump CABG)

Indian cardiac super-specialists are world pioneers in beating heart bypass surgery. Using advanced tissue stabilizers (Octopus devices), surgeons perform micro-vascular anastomoses while the patient's heart continues beating naturally, drastically decreasing transfusion requirements and cognitive post-pump complications.
