Repair of Asymmetric Bicuspid Aortic Valve Using Tricuspidation with CardioCel.

A novel tricuspidation technique was developed for repair of asymmetric bicuspid aortic valves with commissural orientation of approximately 120-140 degrees.

• The technique involves replacement of the fused aortic valve cusp with 2 neo-cusps
• Neo-cusps are fashioned from bovine pericardium (CardioCel) and sutured to the annulus
• The technique is specifically designed for 'very asymmetrical bicuspid aortic valve' with commissural orientation of 'about 120-140 degrees'
• Successful repair requires 'good quality and adequate commissure height of the non-fused cusp'

The tricuspidation technique was applied to 15 patients since 2020 with all patients surviving and maintaining well-functioning aortic valves.

• The technique has been applied to 15 patients since 2020
• To date, all patients are alive
• All patients presented with 'no or trivial insufficiency'
• Patients demonstrated 'large orifice areas, and nearly physiological transvalvular gradients'
