Data provided by company:

• Over 25 years of long-term data for the Masters Series demonstrate low rates of thromboembolic events
• Standard valve first implanted in 1977
• Pyrolytic carbon leaflets and orifice ring offer exceptional durability and increased thromboresistance
• 85 degree leaflet opening angle offers improved laminar flow and reduces turbulence 2-4
• Controlled torque rotation mechanism allows for easy rotation and intraoperative adjustment
• St. Jude Medical heart valves are MR conditional
• Note the difference between calculated EOA by Rosenhek and in vitro calculations

Comments Surgery:

• Bileaflet design, rotation mechanism for intraoperative adjustment, size: 19-31mm, standard, expanded or PTFE cuff

Comments Echocardiography:

• Published hemodynamic data identical for Aortic Regent flex cuff, standard cuff and masters series.
• EOAI identical for masters series and masters HP series
