Impact of previous cardiac operations in patients undergoing surgery for type A acute aortic dissection. Long-term follow up

Aim of this multicenter study was to evaluate the impact of reoperative cardiac surgery for type A acute aortic dissection (TAAAD) on early and long-term outcomes. Patients with history of previous cardiac surgery were included in group R while those undergoing first operation where included in group F. Kaplan-Meier analysis was used to evaluate long-term survival in the two groups. A total of 1472 patients were included in the analysis. Of these, 85 (5.8%) and 1387 (94.2%) were included in group R and F, respectively. Thirty-day mortality was 24% (20 patients) and 18% (249 patients) in groups R and F, respectively(p=0.8). Kaplan-Meier survival at 10 and at 20-year was 51.5% and 30.2% in group R and 48% and 32% in group F (p=0.368). Patients with a history of previous cardiac operations who develop TAAAD can undergo surgery with similar early and long-term outcomes compared to those at their first operation.
