Abstract

In vivo valve function of the artificial valve in patients with St. Jude Medical (SJM) valve and Bicer prosthesis in the aortic position was evaluated both at rest and during exercise after surgery. Effective orifice area was obtained with use of the Gorlin formula. Transaortic pressure gradient was obtained from Gorlin formula in each body surface area.
For 21mm SJM valve, transaortic pressure gradient with body surface area 2.0m² was 9mmHg at rest and 19mmHg during exercise. For 21mm Bicer valve, transaortic pressure gradient with body surface area 2.0m² was 14mmHg at rest and 19mmHg during exercise. From these results it is considered that SJM valve and Bicer valve for the 21mm valve are available in the aortic position.
