Medtronic Hall valve

A tilting-disc-type mechanical prosthesis used to replace a defective aortic valve.
First implanted in 1977, a 25-year followup study of 816 patients receiving the valve revealed minimal complications—thromboembolism, 1.5%/patient-year; Warfarin-related bleeding, 0.7%/patient-year; and endocarditis, 0.16%/patient-year—and no mechanical failures.

She had undergone mitral valve replacement with a 27mm Medtronic Hall prosthesis for severe rheumatic mitral regurgitation in 2005; a permanent pacemaker was implanted when she developed complete heart block postoperatively.
The case is remarkable in that a mitral Medtronic Hall prosthesis was functioning for 3 years without any thrombosis.
