BACKGROUND: Valve preservation in acute type A aortic dissection (ATAAD) can be accomplished with root repair or replacement. Long-term valve durability with root repair has been established, but limited data exist regarding long-term durability of valve-sparing root replacement (VSRR). In this study, long-term results of VSRR were compared with root repair in ATAAD.
METHODS: From 2005 to 2023, 866 patients underwent ATAAD repair, of which 675 underwent root repair and 191 underwent root replacement (VSRR, n = 65; Bentall, n =126). VSRR patients were compared with 123 patients who underwent valve resuspension and root repair with postoperative echocardiograms ≥1 year.
RESULTS: VSRR patients were younger (VSRR, 44 ± 11 years vs root repair, 55 ± 13 years; P < .001). Preoperatively, 57% of VSRR and 35% of root repair patients had moderate or more aortic insufficiency. Cardiopulmonary bypass and myocardial ischemia times were significantly longer in VSRR (P < .001). Postoperative echocardiograms with ≥1 year follow-up were analyzed in 58 VSRR patients with median follow-up of 4.8 years (interquartile range, 3-12 years) and in 123 root repair patients with median follow-up of 3.6 years (interquartile range, 3-8 years). At 10 years, VSRR patients had superior freedom from more than mild aortic insufficiency (VSRR, 91% vs root repair, 49%; P < .001). At 10 years, freedom from aortic valve replacement was equivalent (VSRR, 98% vs root repair, 92%; P = .269).
CONCLUSIONS: VSRR provides equivalent long-term valve durability as root repair in ATAAD, even in patients with moderate or severe aortic insufficiency. In select young patients who require root replacement during ATAAD repair, VSRR represents an ideal therapy.
