In 1977, Karl Viktor Hall implanted a novel tilting disc heart valve prosthesis at Rikshospitalet
in Oslo, Norway. The Medtronic-Hall valve was known for its excellent durability and low …

The functional principle of the new Hall-Kaster pivoting cardiac disc valve is reported.
Results from animal experiments suggested favorable valve hemodynamics. Clinical results …

A prospective randomized study, comparing the clinical results between two groups of
patients undergoing valve replacement with the Monostrut (MS) and Medtronic-Hall (MH) …

Summary Between 1978 and 1982, 230 consecutive patients underwent valve replacement
with the Medtronic-Hall valve prosthesis. There were 95 patients with aortic valve …

When I reviewed the 21-year results with the Björk-Shiley tilting disc valves, I found out that
to date, we still have to use these disc valves and all mechanical heart valves with …

The Hall-Kaster pivotal disc prosthetic heart valve was introduced in 1977. The primary goal
of the design was to obtain the least possible obstruction to flow. Toward this end …

The Bjork–Shiley mechanical heart valve (Shiley Corp, Irvine, CA) was one of the earliest
tilting disc valve prosthesis used for the replacement of diseased cardiac valves. This valve …

Summary The Hall-Kaster central flow prosthetic heart valve was introduced in 1977 in an
attempt to improve the hemodynamics of the disc valve prostheses. Towards this …

The need for better low-profile mechanical valves led to the design and development of the
Medtronic-Hall (formerly known as the Hall-Kaster valve) pivoting disc heart valve prosthesis …

I have just performed what, almost certainly, was the last implantation of a Medtronic Hall
valve (Figure 1) worldwide, 37 years (almost to the day) after its first human implantation. In …
