Balloon Transcatheter Aortic Valve Replacement After Aortic Valve Repair With HAART 300 Device

The HAART 300 (BioStable Science and Engineering, Austin, TX) is a rigid, elliptical device introduced to facilitate aortic valve repair providing annular stabilization in the setting of aortic regurgitation. Percutaneous strategies have been described for patients with dysfunctional biological prostheses or recurrence insufficiency after mitral ring annuloplasty. This report shows the feasibility of aortic valve-in-ring transcatheter aortic valve replacement (TAVR). The sufficient ring stability to support the implanted TAVR-prosthesis and the fact that the elliptical shape of the HAART-ring did not result in a problem concerning paravalvular leakage were important for the success of this procedure.
