Insights
Coronary reoperations with patent arterial grafts show significant long-term benefits. Patients experienced improved heart function and quality of life, justifying the procedure for suitable candidates.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Graft Patency
Background:
- Coronary reoperations are complex procedures.
- Assessing long-term outcomes of repeat coronary artery bypass grafting is crucial.
Purpose of the Study:
- To analyze short and long-term clinical, functional, and subjective outcomes.
- Evaluate patients undergoing repeat coronary artery bypass grafting (RECABG) with patent arterial grafts.
Main Methods:
- Retrospective analysis of 71 patients undergoing RECABG (1987-1998).
- Cross-sectional follow-up included Duke Activity Status Index (DASI) for functional capacity.
- Patient-reported outcomes and life situation were assessed.
Main Results:
- Perioperative mortality was 7%; 60-month survival was 80%.
- Significant improvement in New York Heart Association class (3.4 to 1.5).
- 82% of patients reported benefiting from the reoperation at follow-up.
Conclusions:
- Repeat coronary artery bypass grafting with patent arterial grafts improves functional capacity.
- Positive patient-reported outcomes support the utility of RECABG.
- Improved New York Heart Association class and functional status justify repeat procedures.
Objective:
Analysis of short and long term results, clinical, functional and subjective status of patients, with a patent arterial graft, after coronary reoperation (RECABG).
Methods:
Perioperative and follow-up data of 71 patients, undergoing coronary reoperations (1987--8) were studied. A cross-sectional follow-up was conducted, functional evaluation by the Duke Activity Status Index (DASI), and patient's evaluation of his life situation were registered.
Results:
Perioperative mortality was 7%. Eleven patients died during follow-up. The 12-month and 60-month survival was 96% and 80%. Event-free survival was 86% and 51%. Family doctors declared that 55/66 (83%) had benefitted from the coronary reoperations. New York Heart Association decreased significantly from 3.4 +/- 0.5 preoperative versus 1.5 +/- 0.4 postoperative. The mean DASI was 38.06 +/- 10.42. At the moment of the cross-sectional follow-up, 45/55 patients (82%) declared to have benefitted from the coronary reoperations.
Conclusion:
Improvement in New York Heart Association-class, good postoperative functional capacity, and patients positive evaluation, justify coronary reoperations in patients with a patent internal mammary artery graft.
