Insights
Redo coronary artery bypass grafting (CABG) in carefully selected patients yields satisfactory outcomes. This study of 42 patients demonstrated low mortality and good graft patency, highlighting the importance of appropriate patient selection and management.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Coronary Artery Bypass Grafting
Context:
- Redo coronary artery bypass grafting (CABG) is a complex procedure for patients with previously undergone CABG.
- Evaluating the clinical characteristics and outcomes of redo CABG is crucial for optimizing patient care.
- This study analyzes a cohort of patients undergoing repeat CABG surgery.
Purpose:
- To determine the clinical characteristics and outcomes of patients undergoing redo coronary artery bypass grafting (CABG).
Summary:
- A retrospective analysis of 42 patients who underwent redo CABG between 2002 and 2010.
- The study included both off-pump and on-pump CABG techniques, with some patients requiring concomitant procedures.
- Perioperative mortality was 4.8%, with no residual angina or perioperative myocardial infarction in surviving patients. Follow-up showed good graft patency.
Impact:
- Redo CABG can achieve satisfactory outcomes when proper indications are met and reasonable management strategies are employed.
- The findings support the feasibility and effectiveness of repeat CABG in selected patient populations.
- This research contributes to the understanding of long-term results and graft performance after redo CABG.
Objective:
To determine the clinical characteristics and outcomes of redo CABG.
Methods:
The outcomes of 42 consecutive patients who underwent redo CABG from January 2002 to December 2010 was analyzed. There were 29 males and 13 females, aging from 46 to 78 years old with a mean of (61.2 ± 2.1) years. Off-pump CABG was applied for 31 patients and on-pump CABG for 11 patients. There were 1 patient underwent concomitant aortic valve replacement and 1 patient underwent aortic root and right aortic arch replacement respectively.
Results:
Three patients died of right ventricle rupture, heart failure and multiple system organ failure respectively and the perioperative mortality rate was 4.8%. The post-operatively mechanical ventilation time varied from 9 to 27 h with a mean of (17 ± 7) h. There was no residual angina and perioperative myocardial infarction in the remaining patients who were all discharged uneventfully. Intraoperative 6 patients had accepted intraaortic balloon counterpulsation. During the follow-up from 6 months to 4.5 years for 38 patients, which showed no evidence of recurrent angina and postoperative coronary CT angiography in 12 patients showed the patency of grafts is good.
Conclusion:
Satisfactory outcome of redo coronary artery bypass grafting can be achieved if proper indication were choose and reasonable management were performed.
