Summary
Re-do coronary artery bypass grafting is a viable option for myocardial ischemia despite increased risks compared to the initial surgery. Long-term outcomes are acceptable, though mortality rates remain higher.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Interventional Cardiology
Context:
- Coronary artery bypass grafting (CABG) is a standard treatment for ischemic heart disease.
- Re-operation for CABG is sometimes necessary.
- This study analyzes outcomes of repeat CABG procedures.
Purpose:
- To present the authors' experience with re-do coronary artery bypass grafting.
- To evaluate the efficacy and safety of repeat CABG in patients with ischemic heart disease.
Summary:
- A retrospective analysis of 128 patients undergoing re-do CABG between 1978 and 1996.
- Predominant clinical presentations included unstable angina (76.3%), myocardial infarction (48%), and congestive heart failure (17%).
- Hospital mortality was 10.9%, with perioperative myocardial infarction being the primary cause.
Impact:
- Re-do CABG is effective for myocardial ischemia, though associated with higher mortality and morbidity than primary surgery.
- Improved techniques and interventional cardiology may contribute to stable patient numbers over time.
- Long-term results are satisfactory, but carry a higher mortality risk.
