Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The MH valve is made of a single piece of titanium with no welds. The disk is made of tungsten impregnated graphite with a carbon pyrolytic coating. The tungsten renders the disk radiopaque. In the aortic position the maximal opening is 75˚. A central aperture in the disk allows free rotation. The valve is rotatable in the sewing ring. The sewing ring is made of Teflon. Aortic sizes are 20-31 mm (outer diameter).
The initial clinical results were published in 1979 (1). The cohort of patients has been followed-up and analysed at 5, 10 and 15 years (2-5). In the present study we report our 25-year follow-up data for the 816 patients undergoing aortic valve replacement (AVR) with special reference to survival, functional status, valve-related complications and the impact of concomitant surgery.
