UNLABELLED: OBJECTIVES; This study aimed to investigate the early and late outcomes of patients undergoing aortic valve replacement (AVR) with previous coronary artery bypass grafting (CABG) and patent grafts. METHODS: Between January 2000 and March 2010, 104 patients (87 males) with previous CABG ± concomitant surgery and patent grafts underwent AVR. The median age of the patients was 75 years (range: 37-90 years; inter-quartile range: 69-79 years) and the mean logistic EuroScore was 25.37 ± 16.8. The median time since the previous operation was 9 years (range 1-25; inter-quartile range: 7-14 years). The left internal mammary artery (LIMA) had been used in 75 patients (72.1%) and remained patent in 72 cases (96.0%). RESULTS: Thirty-day mortality was 7.7% (n = 8), which is less than the predicted mean logistic EuroScore. Isolated AVR was performed in 66 patients (63.5%). The LIMA was dissected and isolated (clamped or blocked with balloon) in 60 patients. The median hospital stay was 10 days (range: 4-183 days; inter-quartile range: 7-15.25 days). Nineteen patients (18.3%) had pulmonary complications, while 12 (11.5%) had acute kidney injury. Seven patients (6.7%) required permanent pacemaker. Six LIMAs (8.3%) were injured and repaired. Prolonged aortic cross-clamp (AXC) time (P = 0.038) and the presence of a previous LIMA graft (P = 0.045) were identified as independent predictors of 30-day mortality. The actuarial survival at 1 and 5 years was 89.4 ± 0.3 and 81.5 ± 0.5%, respectively. Perioperative intra-aortic balloon pump use (P = 0.036), prolonged AXC time (P = 0.004) and prolonged cardiopulmonary bypass time (P = 0.022) were associated with worse long-term overall survival on multivariate analysis. CONCLUSIONS: AVR post-CABG with patent grafts can be performed in high-risk patients with excellent short- and long-term outcomes and appears to be superior to published catheter-based interventions. In the absence of randomized trial data, we believe that open AVR remains the treatment of choice for aortic valve disease following prior CABG.
