Abstract

OBJECTIVE: Beta-blockers (BBs) are first-line anti-impulse therapy for patients presenting with acute type B aortic dissection (TBAD). However, little is understood about their effects after aortic repair. The aim of the present study was to evaluate the role of postoperative BB use on the outcomes of thoracic endovascular aortic repair (TEVAR) in TBAD. METHODS: The Vascular Quality Initiative database was queried for all patients who had undergone TEVAR for TBAD from 2012 to 2020. Aortic-related reintervention, all-cause mortality, and the effects of TEVAR on false lumen thrombosis of the treated aortic segment were assessed and compared between patients treated with and without BBs postoperatively. Cox proportional hazards models were used to estimate the effect of BB therapy on the outcomes. RESULTS: A total of 1114 patients who had undergone TEVAR for TBAD with a mean follow-up of 18 ± 12 months were identified. The mean age was 61.1 ± 11.9 years, and 791 (71%) were men. Of the 1114 patients, 935 (84%) continued BB therapy at discharge and follow-up. The patients taking BBs were more likely to have had an entry tear originating in zones 1 to 2 (22% vs 13%; P = .022). The prevalence of acute, elective, and symptomatic aortic dissection, prevalence of concurrent aneurysms, number of endografts used, distribution of proximal and distal zones of dissection, and operative times were comparable between the two cohorts. At 18 months, significantly more complete false lumen thrombosis (58% vs 47%; log-rank P = .018) was observed for patients taking BBs, and the rates of aortic-related reinterventions (13% vs 9%; log-rank P = .396) and mortality (0.2% vs 0.7%; log-rank P = .401) were similar for patients taking and not taking BBs, respectively. Even after adjusting for clinical and anatomic factors, postoperative BB use was associated with increased complete false lumen thrombosis (hazard ratio, 1.56; 95% confidence interval, 1.10-2.21; P = .012) but did not affect mortality or aortic-related reintervention. A secondary analysis of BB use for those with acute vs chronic TBAD showed a higher rate of complete false lumen thrombosis for patients with chronic TBAD and taking BBs (59% vs 38%; log-rank P = .038). In contrast, no difference was found in the rate of complete false lumen thrombosis for those with acute TBAD between the two cohorts (58% vs 51%; log-rank P = .158). When analyzed separately, postoperative angiotensin-converting enzyme inhibitor use did not affect the rates of complete false lumen thrombosis, mortality, and aortic-related reintervention. CONCLUSIONS: BB use was associated with promotion of complete false lumen thrombosis for patients who had undergone TEVAR for TBAD. In addition to its role in the acute setting, anti-impulse control with BBs appears to confer favorable aortic remodeling and might improve patient outcomes after TEVAR, especially for those with chronic TBAD.
