Abstract:
Objective To summarize the short-term therapeutic results of valve-sparing reimplantation procedure (David Ⅰ procedure) using Valsalva conduit in patients with aortic valve insufficiency due to aortic root disease.Methods From January 2008 to May 2011,David Ⅰ procedure was performed using Valsalva conduit in 15 patients with aortic insufficiency caused by aortic root disease,of which 14 males and 1 female,mean age was (49.5 ± 10.3) years old (from 33 to 67 years old).The evaluation of pre-operative heart functional and aortic valve regurgitation:11 in class Ⅰ,4 in class Ⅱ ; 9 with moderate and 6 with severe aortic insuffciency.Concomitant procedures included 4 CABG operations,9 aortic arch replacements,1 mitral annuloplasty and tricuspid annuloplasty,and 1 ASD repair operation.Results There was two intra-operative deaths occurred,one died of pulmonary infection,another one died of hemategenous septic shock and multiple organ failure.The mean extracorporeal circulation time was (230.0 ± 54.4) min,the aortic cross clamp time was (181.2 ± 30.6) min.One week after operation,the heart functional of all patients changed into class Ⅰ ; 8 patients had no aortic regurgitation,6 had gentle aortic regurgitation and 1 had moderate aortic regurgitation.After leaving hospital,13 patients were followed-up by (8.8 ± 5.9)months (ranged 3 to 24 months),3 were no and 9 with gentle (3 of which showed no aortic regurgitation in half past year)and 1 with moderate aortic regurgitation (this patient showed gentle aortic regurgitation in 3 months later).Conclusion David Ⅰ procedure using Valsalva conduit was a good option for patients with aortic valve insufficiency with approximate normal aortic leaflets and valvular ring,which could provide a good short-term operative effect.
