Off-Pump Coronary Artery Bypass (OPCAB)

Off-pump CABG was popularised in the 1990s and 2000s as a way to avoid the inflammatory and neurological consequences of cardiopulmonary bypass. The technique requires advanced stabilisation equipment, intracoronary shunts to maintain distal coronary flow during grafting, and considerable surgeon experience. Large randomised trials (ROOBY, CORONARY) have shown comparable mortality and major adverse cardiac event rates compared to on-pump CABG when performed by experienced operators, with some short-term advantages (stroke, transfusion) and the trade-off of slightly lower graft patency in some series.

Off-pump CABG pricing is typically equivalent to on-pump at the same centre — the operating room time and length of stay are similar, and the avoided cardiopulmonary bypass equipment is offset by specialised stabiliser cost. Total quoted prices cover surgeon's fee, anaesthetic fee, ICU and ward stay (typically 1-2 nights ICU + 3-5 nights step-down), all in-hospital medications, and immediate follow-up. Cardiac rehabilitation may be a separate cost.

Days 0-2: ICU recovery. Extubation typically within hours of OPCAB (faster than on-pump CABG in most series). Aggressive pulmonary toilet to prevent atelectasis. Pain control with regional and systemic analgesia.

Day 3-5: transfer to step-down ward. Mobilisation and chest physiotherapy. Daily review of cardiac rhythm; atrial fibrillation occurs in 20-30% of post-CABG patients and may be managed with rate or rhythm control.

Day 5-7: discharge to local accommodation. Continued mobilisation, regular wound checks, anticoagulant prophylaxis as indicated.

Week 2-3: outpatient cardiology and surgery review. Wound assessment, ECG, and bloods. Continued cardiac rehabilitation referral.

Week 4-6: gradual increase in activity. Walking to 30-45 minutes daily. Return to driving usually permitted at 6 weeks. Sternal precautions (no lifting >2-3kg, no pulling/pushing) continue.

Week 8-12: full sternal healing. Return to most normal activity. Cardiac rehabilitation continues. Lifelong cardiology follow-up begins for management of secondary prevention (aspirin, statin, blood pressure, lipid targets).

Off-pump CABG is offered at a smaller subset of cardiac centres because of the surgical expertise required. Patients considering OPCAB specifically should verify that the destination centre performs the technique routinely (typically >50 OPCAB cases per surgeon per year) and that the proposed surgeon is recognised in OPCAB outcomes data.

Long-haul flying after CABG (on-pump or off-pump) is typically not advised for 3-6 weeks per IATA medical guidance, longer for complex or complicated cases. International patients should plan for an extended in-country recovery and have a clear handover plan to home-country cardiology services for ongoing surveillance.
