Abstract:
Aortic valve replacement with sutureless valves has many potential applications including in redo surgery, minimally invasive scenarios, and heavily calcified aortic roots. Herein we report a case of the development of an aorto-right atrial fistula after replacement of a Medtronic Freestyle stentless subcoronary bioprosthesis (Medtronic Inc, Minneapolis, MN) with a Perceval sutureless valve (LivaNova PLC, London, UK). This eventually necessitated repair with repeat surgery and aortic valve replacement with a stented valve. For patients with failing stentless bioprostheses returning for reintervention, we suggest removal of only Freestyle leaflet tissue without supra-annular debridement to avoid weakening of the native root tissue.
