Article Synopsis
- * The median age at repair was 5.5 months, with a follow-up period of 11 years showing a high survival rate of 96.4% and a 10-year freedom rate from moderate valve regurgitation at 58.4%.
- * Key findings indicated that complete closure of the left-sided atrioventricular valve cleft significantly reduced risk of moderate regurgitation, while incomplete cleft closure was linked to worsened valve conditions post-surgery.

Objective: The purpose of this study was to assess the efficacy of echocardiography-guided ascending aortic central cannulation using the Seldinger technique during surgery for type A acute aortic dissection complicated by stroke due to cerebral malperfusion.
Methods: Between April 2007 and December 2017, 208 patients with type A acute aortic dissection underwent echocardiography-guided ascending aortic central cannulation using the Seldinger technique. We analyzed 16 of these patients (7.
