Abstract:
We present a case of a Staphylococcus epidermidis early prosthetic valve endocarditis after minimally invasive sutureless aortic valve replacement. The patient developed a root abscess with a fistula, severe mitral and periprosthetic regurgitations, with a large mitral vegetation and a residual patent foramen ovale. The surgical approach consisted of a redo median sternotomy, explantation of a sutureless aortic prosthesis, resection of an intervalvular fibrosa and anterior mitral leaflet and debridement of an aortic root-left ventricle outflow tract abscess. These procedures were followed by a root-commando procedure with mitral and aortic root placement using a self-assembled mechanical aortic root conduit. The technique used is an alternative to a root-commando procedure performed with an allograft or a Medtronic Freestyle bioprosthesis. The same technique can be utilized with a commercially available stented bioprosthesis.
