Risk factor analysis for acute XXXX after aortic valve replacement.

@entity1 @entity101 @entity384 @entity337 @entity1580
PURPOSE: Previous aortic valve replacement (AVR) is considered to be an independent risk factor for late acute @entity1580 (AAAD). However, the predictors of late AAAD at the time of AVR have not been characterized. METHODS: A total of 285 @entity1 who underwent isolated AVR were followed for 7.6    8.1 years (mean    SD). These 285 @entity1 were divided into two groups. Group A consisted of 275 @entity1 who did not develop late aortic complications after AVR, and group B consisted of 10 @entity1 (3.5%) who developed late AAAD after AVR. RESULTS: The mean time interval between initial AVR and developing late AAAD was 6.1    5.2 years. The diameter of the ascending aorta at the time of AVR was significantly greater in group B than those of group A (47.7    4.6 vs. 35.6    6.3 mm; P < 0.001). Univariate analysis identified other predictors as well: @entity337 (P = 0.029), systemic @entity101 (P < 0.001), thinning or fragility of the aortic wall (P < 0.001), and male sex (P = 0.039). CONCLUSION: @entity337 combined with systemic @entity101 , male sex, and thinned or fragile aortic walls in @entity1 with ascending @entity384 (>= 45 mm diameter) at the time of AVR may be predisposing factors for postsurgical aortic complications. These @entity1 should be considered for concomitant replacement of the ascending aorta unless the @entity1 has a high operative risk or older age.
