Aortic root surgery in acute aortic dissection type-A – new insights from GERAADA (German Registry for Acute Aortic Dissection type-A) after three years
Objectives: The proper surgical treatment of the aortic root in patients with acute aortic dissection type A (AADA) remains an issue of debate. Here we analyse the GERAADA-data aimed to identify a trend towards a favourable technique.
Methods: During 7/2006 until 6/2009, 45 centers reported of 1610 patients with AADA. 1558 patients were included, with 956 (61%) men and a mean age of 60 (11–89) years. Treatment of aortic root during surgery was supracommissural replacement (SR; n=1053; 67.6%), Composite graft (C; n=332; 21.3%), David procedure (D; n=107; 6.9%), and Yacoub procedure (Y; n=32; 2.1%). Intraoperative times, adverse events and outcome were compared.
Results: Overall mortality after 30 days was 16%. Mortality was borderline significant lower in D (9.4%; p=0.050), and similar in Y (15.6%; p=0.95), SR (16%; p=0.89) and C (19%; p=0.1) (compared to all patients). Postoperative bleeding was significant higher in C (27.7%; p=0.008) and lower in SR (20.5%; p=0.0126), and similar in D (22.4%; p=0.98) and Y (21.9%; p=0.95). Consequently, need for rethoracotomy was significant lower only in SR (17.2%; p=0.011; average 19%). The incidence of new postoperative neurological events was significant higher in C (13.3%; p=0.044; average 10.3%), while new postoperative malperfusion was significant lower in D (0.93%; p=0.012; average 6.9%). Mean aortic cross clamp time was longest for D (145; 46–309min.) and shortest for SR (87; 7–276min.; Y: 97; 50–197min.; C: 129; 43–450min.).
Conclusions: In patients with AADA, valve sparing techniques of root reconstruction, in particular the David procedure can be performed with favourable results. However, surgeons experience and preoperative status of patients may influence outcome even more than the chosen technique of root repair.
