Conventional cardiopulmonary bypass (CPB) in coronary artery bypass grafting (CABG) offers extensive revascularization. Off-pump techniques suit specific patient groups, but minimizing CPB exposure is key to reducing risk.

Area of Science:

  • Cardiac Surgery
  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Surgery

Background:

  • Cardiopulmonary bypass (CPB) in coronary artery bypass grafting (CABG) is associated with increased postoperative complications in high-risk individuals.
  • Exploring alternative surgical strategies to mitigate risks associated with CPB is crucial for improving patient outcomes.

Purpose of the Study:

  • To retrospectively compare outcomes of conventional CABG with a fast-track recovery method against off-pump beating heart surgery techniques.
  • To evaluate the efficacy of minimally invasive direct coronary artery bypass (MIDCAB) and off-pump multivessel bypass in different patient cohorts.

Main Methods:

  • Retrospective review of 158 consecutive CABG patients.
  • Group A: Conventional CABG with CPB and fast-track recovery (n=104).

  • Group B: Minimally invasive direct coronary artery bypass (MIDCAB) off-pump (n=29).
  • Group C: Off-pump multivessel CABG with median sternotomy (n=25).

    • Main Results:

    • Fast-track CPB group (A) showed minimal complications and rapid recovery with extensive revascularization.
    • Off-pump multivessel group (C) had higher comorbidity, fewer grafts, but similar recovery to Group A.
    • MIDCAB group (B) had no apparent recovery advantage despite being younger and elective.
    • Overall mortality was 1.8%; conversion rates for off-pump to CPB were 10.3% (B) and 16% (C).
    • Postoperative hospital stay: Group A (4.8 days), Group B (3.9 days), Group C (5.2 days).

    Conclusions:

    • Reducing CPB exposure, not necessarily eliminating it, is key to minimizing operative risk.
    • Off-pump multivessel bypass is suitable for high-risk patients needing ≤3 grafts; MIDCAB for single-vessel bypass unsuitable for percutaneous intervention.
    • Patients requiring >3 grafts benefit most from conventional CABG with CPB.
