BACKGROUND: Atrial fibrillation (AF) is a relatively common comorbidity among patients referred for coronary artery bypass grafting (CABG) and is associated with poorer prognosis. However, little is known about how surgical technique influences survival in this population.
AIM: The current analysis aimed to determine whether total arterial revascularization (TAR) is associated with improved long-term outcomes in patients with preoperative AF.
METHODS: We analyzed patients' data from the HEIST (HEart surgery In atrial fibrillation and Supraventricular Tachycardia) registry. The registry, to date, involves five tertiary high-volume centers in Poland. Between 2006 and 2019, 4746 patients presented with preoperative AF and multivessel coronary artery disease and underwent CABG. We identified cases of TAR and used propensity score matching to determine non-TAR controls. Median follow-up was 4.1 years (interquartile range [IQR], 1.9-6.8 years).
RESULTS: Propensity matching resulted in 295 pairs of TAR vs. non-TAR. The mean (standard deviation [SD]) number of distal anastomoses was 2.5 (0.6) vs. 2.5 (0.6) (P = 0.94) respectively. Operative and 30-day mortality was not different between TAR and non-TAR patients (hazard ratio [HR] and 95% confidence intervals [CIs], 0.17 (0.02-1.38); P = 0.12 and 0.74 [0.40-1.35]; P = 0.33, respectively). By contrast, TAR was associated with nearly 30% improved late survival: HR, 0.72 (0.55-0.93); P = 0.01. This benefit was sustained in subgroup analyses, yet most pronounced in low-risk patients ( < 70 years old; EuroSCORE II < 2; no diabetes) and when off-pump CABG was performed.
CONCLUSIONS: TAR in patients with preoperative AF is safe and associated with improved survival, with particular survival benefits in younger low-risk patients undergoing off-pump CABG.
