title: The narrow aortic annulus. A technique for inserting a larger prosthesis.
abstract: A surgical method is described which enables a relatively larger aortic prosthetic valve to be inserted. This consists of widening the aortic root with pericardium and inserting the prosthesis slightly obliquely. The technique has been successfully applied in all 12 patients on whom it was attempted.
