Repeat coronary artery bypass grafting (CABG) is performed in 3.28% of patients. Reoperation offers symptomatic improvement in 85% of cases, but carries a 5% operative mortality. Cardiac transplantation is a viable alternative for select patients.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery
  • Interventional Cardiology

Background:

  • Repeat coronary artery bypass grafting (CABG) is a complex procedure for patients with previously revascularized coronary arteries.
  • Understanding the characteristics and outcomes of reoperated patients is crucial for optimizing care.

Purpose of the Study:

  • To analyze the characteristics, risk factors, and outcomes of patients undergoing repeat CABG.
  • To compare reoperation data with the general population undergoing bypass surgery.
  • To evaluate cardiac transplantation as an alternative for specific patient groups.

Main Methods:

  • Retrospective analysis of 138 patients who underwent repeat CABG between June 1976 and June 1989.
  • Comparison of perioperative morbidity and mortality with a general bypass surgery population.

Related Experiment Videos

  • Review of outcomes for 11 patients who underwent cardiac transplantation.

    • Main Results:

    • Reoperated patients had a mean age of 59 years, with a mean interval of 73 months between surgeries.
    • 65% presented with three-vessel disease; mean ejection fraction was 55%.
    • Perioperative infarction occurred in 8.0%, operative mortality was 5%, with 85% achieving symptomatic improvement. Cardiac transplantation had no postoperative deaths.

    Conclusions:

    • Repeat CABG can provide symptomatic improvement but involves significant perioperative risks.
    • Cardiac transplantation emerges as a potentially superior alternative for patients with severely impaired ventricular function post-bypass.
