Although numerous surgical techniques are employed to treat acute Stanford type A aortic dissection (ATAAD), controversy remains over which is the best procedure for aortic root reconstruction. Among the various techniques utilized, neomedia repair is considered to be more promising than adhesive-only repair for the treatment of a dissected aortic root. We experienced a series of neomedia sinus valsalva repair using woven polyester fabric, and evaluated the aortic root diameter by computed tomography and severity of aortic valve insufficiency by transthoracic echocardiography. The aortic root diameter was well preserved with no progress of aortic valve insufficiency in the long-term period. Furthermore, we found that the fabric looked functioning new media in the findings obtained from the pathological examination of a neomedia repaired aortic wall sample that was obtained by chance from a patient during valve replacement surgery performed 10 years after aortic reconstruction for ATAAD. Neomedia repair using woven polyester fabric for ATAAD might facilitate the long-term durability of the surgically treated aortic root.
