Disclosures: None Aortic Symposium 2010 Sheraton Hotel and Towers, New York, USA.

  2. Background • In the last decade, results of aortic valve repair were dramaticaly improved in term of mortality and freedom from aortic valve regurgitation and reoperation • Several techniques were used for aortic valve repair in bicuspid and tricuspid aortic valve.

  3. Study endpoints • To assess postoperative outcome of aortic valve repair according to: • Valve morphology (tricuspid or bicuspid) • Surgical techniques: plication, free edge reinforcement with Gore-Tex, “chordae technique” (described by us)

  4. Study Endpoints Evaluate the impact of AV repair on 6-year freedom: • from overall and cardiac-related death • from reoperation on aortic valve • from reccurrent aortic valve regurgitation grade ≥ II Valve-related events were as follows: reccurent AR, reoperation, endocarditis, stenosis, trombo-embolism.

  5. Patients and Methods • Since February 2003, 216 patients with aortic regurgitation underwent valve repair in our institution. • Patients were classified preoperatively according to functional classification: Type I in 55 pts (25.5%), Type II in 126 (58.3%) and Type III in 35 (16.2%). • 66 pts (27.7%) had bicuspid valve

  10. Freedom from reoperation and from recurrence of AR ≥ grade II Freedom from reoperation was 94.8% Freedom from AR grade ≥ II was 85.5% years

  15. Conclusions • Aortic valve repair can be performed • with low early (2.7%) and late mortality. • Late survival rate was 91.5% and late cardiac related death • was 6%. • Overall 6-year aortic regurgitation recurrence (grade≥2) • was 14.5% • Overall incidence of aortic valve reoperation after valve • repair was 5.2%.

  16. Conclusions • Optimal results was observed for tricuspid and pliable bicuspid valve • Optimal results was observed for Type I and II. • Better results for plicatio and The chordae technique respect to only free edge reinforcement
