Enlargement of the aortic annulus using a double-patch technique: a safe and effective method.
We have tested a new method to enlarge the aortic annulus using a double-patch technique after the Manouguian principle. Our study included 14 patients who had no operative mortality and no complications; long-term follow-up was 13 years. The method prevented mitral insufficiency and operative bleeding at the aortic root.
