Sakiyalak P 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.
