Abstract 16503: Comparison of Long-Term Results After Treatment of Ascending Aortic Aneurysms by Different Surgical Techniques

Background: The proper treatment of aneurysm of the ascending aorta is still under debate. Here we compare the early and late outcome of patients undergoing composite replacement (CR), supracomissural aortic replacement (SCR) and aortic valve sparing operation (AVS) for treatment of aneurysm of the ascending aorta. Patients and Results: From 1994 until 2010, 287 patients (pts) were operated for ascending aortic aneurysm. 79 pts (28%) underwent SCR, 161 pts (56%) had CR, 47 pts (16%) were operated with AVS using David's technique (D) (34 pts; 12%) and 13 pts (4%) using Yacoub's technique (Y). Average sizes of aneurysms were 5.9±1.4 in SCR, 6.3±1.5 in CR, 5.5±0.8 in D and 7.7±2.2 cm in Y and differ significantly between groups (p<0.001). 70% of pts were male, with significant less male patients in Y (p=0.01). Average age with 60±14 years was comparable (p=0.22). Presence of bicuspide aortic valve was comparable (p=0.64), but Marfan's syndrome was more often present in AVS (p=0.005). Average bypass times wer...
