The aim of this study is to analyse the short-term results of the first patients undergoing the OZAKI procedure (Aortic valve reconstruction using autologous pericardial tissue) at the department of cardiac surgery/ University Hospital Basel/ Switzerland.
The reconstruction of the aortic valve using autologous pericardium, applying the technique Ozaki et al., published first in 2011 provides potential benefits due to the missing necessity of oral anticoagulation and its use in patients with small aortic annuli, because of the huge orifice area. There is a need of more data to evaluate the significance of this technique in the treatment of aortic valve stenosis and regurgitation. The department of cardiac surgery/ University Hospital Basel/ Switzerland started to use this technique in September 2015. The aim of this study is to analyse the short-term results of the first patients undergoing the OZAKI procedure.
