Background and Aims The optimal valve and prosthesis in patients with aortic valve infective endocarditis with annular abscess is controversial. If extensive annular defects occur after debridement, standard techniques are difficult; more complex aortic root replacement (ARR) or aortic valve translocation technique are inevitable. The Solo Smart stentless bioprosthesis is specially designed for supra‐annular implantation without annular stitches. Methods Nineteen patients with active aortic valve infective endocarditis underwent aortic valve replacement in the past 3 years. Of these, we performed aortic valve replacement using the Solo Smart valve in four patients with extensive annular destruction and complex aortic root pathologies requiring reconstruction. Results Although more than two‐thirds of the annular structure was missing after radical debridement of infected tissues, supra‐annular aortic valve replacement with the Solo Smart valve could be performed successfully in all four patients. All patients are doing well without prosthetic valve dysfunction and/or recurrent infection. Conclusion The supra‐annular aortic valve replacement using the Solo Smart valve is considered to be a useful alternative to standard aortic valve replacement in patients complicated with extensive annular defect. It is a simple and technically less demanding alternative to ARR or aortic valve translocation technique.
