Key result
Aortic root enlargement with oblique valve insertion accommodates prostheses up to 2 sizes larger without impairing closure.
Why the study?
The host aortic annulus may not allow insertion of a substitute valve of appropriate size in patients with a narrow aortic root.
Does aortic root enlargement with oblique insertion of a St Jude Medical valve allow for larger prosthetic valve sizes without affecting valve closure in patients with a narrow aortic root?
Population
11 patients with narrow aortic root undergoing valve replacement
Comparison
Aortic root enlargement and oblique insertion of larger St Jude Medical valve vs standard valve size insertion
Design

Does aortic root enlargement with oblique insertion of a St Jude Medical valve allow for larger prosthetic valve sizes without affecting valve closure in patients with a narrow aortic root?
Aortic root enlargement with oblique insertion of a St Jude Medical valve allows for the use of larger prostheses without compromising valve closure in patients with narrow aortic annuli.
Kinsley et al. (1983) conducted an observational in Narrow aortic root (n=11). Aortic root enlargement and oblique insertion of a St Jude prosthesis was evaluated on Valve closure and accommodation of larger prosthetic valve. Aortic root enlargement and oblique insertion of a St Jude Medical valve allowed for prostheses 1-2 sizes larger than the host annulus without affecting valve closure in 11 patients.
