[Surgical repair of extracardiac unruptured aneurysm of the sinus of Valsalva].
ABSTRACT An isolated extracardiac unruptured aneurysm of the non-coronary sinus of Valsalva was detected incidentally in a 49-year-old woman with chronic obstructive pulmonary disease. The orifice of the aneurysm was closed with XAG-400 patch. The aortic valve was normal. 20 cases of successful operation have been reported in Japan with extracardiac unruptured aneurysm. In the review of the literature, patch closure of the orifice of the aneurysm was the standard procedure in most cases. However, aortic root replacement was required in some cases with concomitant cardiac and/or aortic disease.
