Background: The optimal surgical technique and valve prosthesis in patients with active 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 is inevitable. The SOLO SMART stentless bioprosthesis is specially designed for supra-annular implantation without annular stitches.
Methods: Since 2016, 15 patients with active aortic valve infective endocarditis underwent aortic valve surgery. Of these, we performed aortic valve replacement using the SOLO SMART valve in six 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 six patients. All patients are doing well without prosthetic valve dysfunction and/or recurrent infection.
Conclusions: The supraannular 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 aortic root replacement.
