There was a lack of communication between Shiley and the FDA as he somehow got the prosthetic valve approved for patient use in Every year, there are aro Americans who seek to replace their faulty heart valves. Bjork-Shiley artificial heart valves are disc valves with a low profile, high orifice-to-tissue ratios, low embolic rates, and good hemodynamics.

The minor orifice would often clog up because of its small opening.

The BSCC tilting disc valve was designed to replace the original radial spherical (R/S) model, which was prone to valve thrombosis. The BSCC heart valve was considered an improvement over the earlier version because its strength was increased by making the inlet strut part of the orifice ring and doubling the cross-section area, thus improving hydrodynamics and eliminating the area of Cited by: 7.
