Abstract:
Objective:To explore the prognosis and risk factors for conversion from off-pump coronary artery bypass grafting (OPCABG) to coronary bypass grafting (CABG) during surgery.
Methods: We retrospectively analyzed 2613 patients with elective OPCAB in our hospital from 2001 to 2012, there were 62 (2.37%) patients converted to CABG during the operation as Conversion group, the rest 2551 patients were set as Non-conversion group. The peril-operative baseline clinical data and prognosis condition were compared between 2 groups. The risk factors causing the in-operative conversion were studied with binary logistic regression analysis.
Results: The total conversion rate was 2.37%, including 42 patients of hemodynamic instability, 6 with dififculty of target vessel exposure, 9 with malignant arrhythmia, 3 with graft occlusion and 2 patients with other reasons. Compared with Non-conversion group, the Conversion group had increased post-operative drainage and ventilation time, higher rates of second thoracotomy for stop bleeding and higher peril-operative mortality. Binary logistic regression analysis indicated that chronic obstructive pulmonary disease, previous history of CABG, NYHA class≥3, LVEF≤40%and left main disease were the independent risk factors for in-operative conversion.
Conclusion: Conversion from OPCAB to CABG during the operation would be result in signiifcantly higher morbidity and mortality in relevant patients.
