Abstract A 35-year old female patient underwent a double valve replacement. The operative findings revealed a small aortic annulus (about 17 mm in diameter). In order to implant the adequate-size prosthetic valve, the aortic and mitral annulus were enlarged using the technique described by Rastan and Manouguian. The annulus were enlarged with a patch of gel-sealed dacron graft. After the enlargement, the prosthetic valve No. 23A and 31M could be implanted in the aortic and mitral annulus, respectively. This is an effective technique to enlarge the aortic and mitral annulus in a double valve replacement procedure. The annular diameter could be increased approximately 30 per cent.
