Abstract:
To quantify contemporary outcomes following elective ascending aortic aneurysm repair, to determine risk factors for adverse events and to evaluate difference by institutional surgical volume. Methods We included all elective hospitalisations of adult patients with an ascending aortic aneurysm who underwent aneurysm repair in the Nationwide Readmissions Database between 2016 and 2019. The primary outcome was a composite of in-hospital mortality, stroke (ischaemic and non-ischaemic) and myocardial infarction (MI). We identified independent predictor of adverse events and investigated outcomes by institutional volume. Results Among 12 043 patients (mean 62.8 years of age, 28.0% female), MI, stroke or in-hospital death occurred in 598 (4.9%) patients during the index admission (acute stroke: 2.7%, MI: 0.7%, in-hospital death: 2.0%). The strongest predictors of in-hospital death, stroke or MI were chronic weight loss, pulmonary circulation disorder and concomitant descending aortic surgery. Higher procedural volume was associated with a lower incidence of in-hospital death, stroke or MI (OR comparing the highest with the lowest tertile 0.71, 95% CI 0.57 to 0.87; p=0.001) and in-hospital death (OR 0.51, 95% CI 0.37 to 0.72; p 〈 0.001), but no difference in 30-day readmissions. Conclusions The overall rate of in-hospital death, stroke and MI is nearly 5% in patients undergoing elective ascending aortic aneurysm repair. Among several predictors, chronic weight loss is associated with the largest increase in the risk of poor outcomes. Higher hospital volume is associated with a lower in-hospital mortality, highlighting the importance to refer patients to high-volume centres while discussing the risks and benefits of proceeding with repair.
