OBJECTIVES: The aim of this study was to assess the impact of aortic valve morphology and different surgical aortic valve repair techni-ques on long-term clinical outcomes.METHODS: Between February 2003 and May 2010, 216 patients with aortic insufficiency underwent aortic valve repair in our institu- tion. Ages ranged between 26 and 82 years (mean 53 ± 15 years). Aortic valve dysfunctions, according to functional classification, were: type I in 55 patients (25.5%), type II in 126 (58.3%) and type III in 35 (16.2%). Sixty-six patients (27.7%) had a bicuspid valve. Aortic valve repair techniques included sub-commissural plasty in 138 patients, plication in 84, free-edge reinforcement in 80, resection of raphe plus re-suturing in 40 and the chordae technique in 52. Concomitant surgical procedures were CABG in 22 (10%) patients, mitral valve repair in 12 (5.5%), aortic valve-sparing re-implantation in 78 (36%) and ascending aorta replacement in 69 (32%). Mean follow- up was 42 ± 16 months and was 100% complete.RESULTS: There were six early deaths (2.7%). Overall late survival was 91.5% (18 late deaths). There were 15 (6.9%) late cardiac-related deaths. NYHA functional class was ≤II in all patients. At follow-up, 28 (14.5%) patients had recurrent aortic insufficiency ≥ grade II. The freedom from valve-related events was significantly different between bicuspid and tricuspid valve implantation (P < 0.01), between type I + II and type III (P < 0.001) dysfunction and between the chordae technique and plication, compared to free-edge reinforcement (P < 0.01). Statistically-significant differences were found between patients who underwent aortic valve repair plus root re-implantation, compared to those who underwent isolated aortic valve repair (P = 0.02).CONCLUSIONS: aortic valve repair including aortic annulus stabilization is a safe surgical option with either tricuspid or bicuspid valves; even more so if associated with root re-implantation. Patients with calcified bicuspid valves have poor results.
