Limited Root Repair in Acute Type A Aortic Dissection Is Safe but Results in Increased Risk of Reoperation

This Stanford group retrospectively reviewed their experience over a 10-year period with 293 patients who underwent either limited aortic root repair or root replacement.  

Results:

• No significant difference in weighted perioperative mortality.
• No significant difference in weighted survival.
• However, there was a significantly higher rate of later reoperation in the limited root repair group (11% versus 0%, p<0.001).
