Summary
Repeat coronary artery bypass grafting (CABG) offers significant symptomatic improvement and therapeutic benefit for many patients. This study shows reoperation success rates approaching primary surgery, with low morbidity and mortality.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Atherosclerotic Disease Progression
Context:
- 106 previously revascularized patients underwent repeat aorto-coronary bypass (CABG) between 1978-1988.
- This represented 3.01% of all CABG procedures during the period.
- Analyzed characteristics, risk factors, and outcomes compared to primary revascularization.
Purpose:
- To analyze the characteristics, risk factors, and perioperative outcomes of patients undergoing repeat CABG.
- To compare outcomes of reoperation with primary bypass surgery.
- To discuss causes of recurrent angina and graft failure.
Summary:
- Repeat CABG patients averaged 58.5 years old, with a mean 66-month interval between surgeries.
- 75% had three-vessel disease and reduced ejection fraction (55%).
- 85% experienced symptomatic improvement, with 5.7% operative mortality and 10.5% perioperative infarction.
Impact:
- Coronary reoperations achieve success rates comparable to primary CABG.
- Repeat CABG demonstrates low morbidity and mortality, offering therapeutic benefit.
- Highlights the progression of atherosclerotic disease and graft attrition (2% annually).
