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:
• Warfarin-related bleeding–0.7%/patient-year
• Endocarditis—0.16%/patient-year and no mechanical failures.
