Aortic root operations are established procedures for patients with aortic root aneurysms, however there is a little insight for comparative long-term outcomes among different types of anatomical abnormalities and procedures. In this study, we sought to compare the results of patients with aortic abnormalities undergoing different procedures. From January 2008 to March 2017, a total of 105 patients without aortic dissection were performed the elective aortic root surgery. Patients with bicuspid aortic valve had enlarged annulus, and those with Marfan syndrome had enlarged Valsalva without enlarged annulus. Bentall operation with mechanical valve or bioprothetic valve was performed for patients with enlarged annulus and/or abnormal aortic cusp, and David operations for patients with normal cusps. This comparative study showed that these different procedures according to our policy were associated with reduced cardiac mortality and valve-related complications. The results suggest David procedure is the treatment of choice for young patients with aortic root aneurysm and normal aortic cusps, however, careful patient selection is paramount.
