Abstract

Objective: To investigate the value of bedside echocardiography in diagnosis and risk assessment of in-hospital death of patients with Stanford type A aortic dissection. Methods: The clinical data of 229 patients with Stanford type A aortic dissection diagnosed by CT angiography in Zhongshan Hospital affiliated to Fudan University between January 2009 and January 2016 were retrospectively analyzed. The patients were divided into survival group(191 cases)and non-survival group(38 cases)according to presence or absence of in-hospital death. The bedside echocardiography features were analyzed, and influence factors of in-hospital death were determined by multivariate logistic regression analysis. Results: (1) Compared with the survival group, the non-survival group had lower surgery rate (60.52%(23/38) vs. 85.34%(163/191), P<0.01). Age, gender and Debakey classification were similar between survival group and death group (all P>0.05). (2) The bedside echocardiography results showed that prevalence of aortic valve involvement(65.79%(25/38) vs.34.03%(65/191), P<0.01) and severe aortic regurgitation (44.74%(17/38) vs. 14.14%(27/191), P<0.01) were significantly higher in non-survival group than in survival group. The non-survival group had larger aortic root diameter than the survival group ((55.5±6.4)mm vs. (42.3±7.8)mm, P<0.01). There were no significant differences in pericardial effusion, expansion of aortic sinus, and left ventricular ejection fraction between survival group and non-survival group (all P>0.05). (3) The multivariate logistic regression analysis showed that aortic valve involvement(OR=3.275, 95%CI 1.290-8.313, P<0.05), aortic root diameter(OR=1.202, 95%CI 1.134-1.275, P<0.01), and surgery (OR=0.224, 95%CI 0.079-0.629, P<0.01) were independent risk factors for in-hospital death in patients with Stanford type A aortic dissection. Conclusions: Bedside echocardiography has significant diagnostic value for Stanford type A aortic dissection. Aortic valve involvement, enlargement of aortic root diameter and without surgery are independent risk factors for patients with Stanford type A aortic dissection.
