Aortic Root Wrapped Procedure for Treating Aortic Root Sinus Aneurysm.

Background. To develop a relatively simple and effective and low-risk operation, aortic root wrapped procedure, to treat aortic root aneurysm or ectasia. Methods. From June 2008 to September 2010, 15 patients were accepted for aortic root wrapped angioplasty procedure, Marfan's syndrome with aortic root ectasia in 2 cases, and aortic sinus aneurysm with middle to severe aortic valve stenosis and/or regurgitation in 13 cases. The diameter of aortic valve annulus was 25.43 +/- 2.34 mm (range = 22-32 mm) and the diameter of aortic sinus was 50.45 +/- 7.32 mm (range = 45-60 mm). All patients underwent aortic root wrapped angioplasty procedures with artificial blood vessel combined with aortic valve plasty or replacement with tissue valve prosthesis. Results. Fifteen patients survived well, and the perioperative mortality was 0%. Cardiopulmonary bypass time was 82.31 +/- 16.34 minutes (range = 55-128 minutes). Predischarge echocardiography check result showed trace aortic regurgitation in 3 cases and normal aortic valve function in 12 cases. Compared with preoperative echocardiography results, the aortic annulus diameter (22.63 +/- 1.25 mm [range = 21-25 mm]) decreased significantly (P < .01) and the aortic sinus diameter (36.86 +/- 7.41 mm [range = 30-41 mm]) decreased significantly (P < .001). Follow-up results: All 15 patients survived well, and heart function (New York Heart Association classification) of the patients are all class I. The late mortality was 0%. Conclusion. Aortic root wrapped procedures combined with aortic valve plastic or replacement operation is an alternative surgical procedure in patients with aortic sinus aneurysm and aortic valve disease.
