Abstract:
Objective To determine the feasibility of OZAKI procedure aortic valve neo-cuspidization(AVneo) for the treatment of aortic valve disease in our institution.Methods Twelve consecutive patients from November 2015 to October 2016 received AVneo in our single center are retrospected.Their mean age was(41.3 ± 16.9) years old.There were 11 males and 3 females.3 patients had aortic stenosis and 11 patients had aortic insufficiency.Autologous pericardium was used to reconstruct 3 aortic leaflets independently.The distance between each commissure was measured by a specific sizer to decide the size of each leaflet.Suturing the pericardial leaflets onto each aortic annulus.Results There was no perioperative mortality.No operations converted to prosthetic valve replacement.1 patient experienced IABP therepy for 2 days,for ventricular tachycardia repeatedly happened when cardiac rebeating intraoperation.Echocardiography one week after surgery showed an average maximum flow velocity of aortic valve of(162.9 ± 34.2) cm/s,average peak pressure gradient of(11.1 ± 4.9) mmHg (1 mmHg =0.133 kPa).Except 1 patient had moderate regurgitation after surgery,the rest of 13 patients showed less than mild aortic regurgitation.Conclusion OZAKI procedure AVneo provides good short-term results in patients with various aortic valve disease.
