Summary

Off-pump coronary artery bypass grafting (CABG) allows complete myocardial revascularization without cardiopulmonary bypass (CPB). This technique is safe and effective, even in patients with comorbidities.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Innovation
  • Minimally Invasive Cardiac Procedures

Background:

  • Complete myocardial revascularization is achievable on a beating heart.
  • Excellent visualization, exposure, and stabilization are key for off-pump surgery.
  • Cardiopulmonary bypass (CPB) is not always necessary for successful coronary artery bypass grafting (CABG).

Purpose of the Study:

  • To evaluate the safety and efficacy of off-pump CABG.
  • To demonstrate complete revascularization without CPB.
  • To assess outcomes in a large patient cohort undergoing off-pump procedures.

Main Methods:

  • 300 patients underwent total revascularization via median sternotomy using myocardial stabilization.
  • The CardioThoracic System was employed for stabilization.

  • Off-pump coronary artery bypass grafting (CABG) was performed using sequential coronary occlusion and multiple arterial grafts.

    • Main Results:

    • An average of 3.4 grafts were placed per patient.
    • Conversion to CPB was required in 6% of cases.
    • Low unadjusted mortality (2.3%) and stroke rate (0.7%) were observed, with comorbidities like diabetes (48%) and prior myocardial infarction (28%) not being limiting factors.

    Conclusions:

    • Complete revascularization can be safely accomplished without cardiopulmonary bypass.
    • Off-pump CABG is a viable and safe alternative to traditional bypass surgery.
    • The technique is effective across a range of patient comorbidities.
