  2. OBJECTIVE • Evaluate the early clinical outcomes of aortic root surgery in the United States. • Identify the trends in aortic root procedures over the years

  3. Methods • N= 13,743 • Period of study: January 2004 to December 2010 • Median age: 58 years (range 18-96 years) • Females: 3,961 (29%) • Concomitant ascending aortic aneurysm (n=8,472)

  4. Aortic Root Procedures • Mechanical Valve-Conduits: 37% • Stented pericardial valve conduits:7% • Stented porcine valve conduits: 4% • Stentless root: 34% • Homograft: 3% • Valve sparing root replacement: 15%

  5. Conclusion • The great majority of aortic root surgery is perfomed in a small number of centers • The unadjusted operative mortality is higher in patients over 80 years old, while valve sparing root surgery is associated with the lowest mortality • There was a trend towards increased use of stented tissue valves over the last few years
