Objective:
To retrospectively analyze the ascending aortic diameter (AAD) changes in patients after mechanical aortic valve replacement (AVR).Methods:
The medical records and echocardiography reports in patients who received AVR or bivalve valve replacement (BVR) in our hospital from 2000-01 to 2001-12 were retrieved, the retrieval conditions were as aortic valve structure must be mechanical and the follow-up echocardiography examination should be more than 9 years. The clinical information, pre- and post-operative 2-dimentional transthoracic echocardiography reports were collected, the follow-up echocardiography periods were ≤3-year, 3-year9-year. AAD changes at different periods were compared. According to baseline AAD, the patients were divided into AADResults:
A total of 141 patients were enrolled form 595 echocardiography reports which included 75 male, the patients were at the mean age of (45.5 ± 11.2) years with mean follow-up time of (7.59 ± 3.38) years. Compared with baseline level, the follow-up AAD was similar between ≤3-year and 3-year0.05; while the follow-up AAD was different between 6-year9-year patients,PConclusion:
AAD dilatation were gradually occurring after mechanical AVR, the patients with AAD≥35 mm had the higher risk for ascending aortic events, therefore special attention should be taken in patients with aortic valve disease combining AAD dilatation during surgical treatment.
