The case is presented of an unusual complication after aortic valve replacement with a Freedom Solo bioprosthesis. Excision of the aortic valve created a discontinuity of the aortic annulus that was missed intraoperatively and left uncorrected after supra-annular placement of the bioprosthesis; this created a pseudoaneurysm with direct communication to the pericardial cavity. When implanting the Freedom Solo bioprosthesis, care must be taken to exclude the presence of any aortic annular discontinuity. Implantation of the Freedom Solo bioprosthesis is not precluded by this possible complication, provided that any annular disruption is promptly recognized and adequately closed before placement of the supra-annular sutures.
