Abstract
A method for evaluating a valve annulus to determine a size of a prosthetic heart valve to be sewn to the valve annulus during heart valve replacement surgery. The prosthetic heart valve includes an annular extension having a first flexibility and a sewing ring having a second flexibility. A flexible sizer body is provided and includes an outer ring and an annular wall coupled to and extending from the outer ring. The annular wall has a flexibility substantially similar to the first flexibility of the annular extension of the prosthetic heart valve. The flexible sizer body is inserted into the valve annulus and a determination made as to fit and conformance. A prosthetic heart valve is selected based on the determination.
