Acute dysfunction of Liotta mitral bioprosthesis 8 years after implantation
2002
: The low-profile porcine bioprosthesis Liotta was introduced in clinical practice in order to reduce the potential complications related to excessive protrusion of the stent into the left ventricle after mitral valve replacement. Otherwise the particular design of this device seems to determine an excessive stress at the commissural level. We describe a case of acute dysfunction of the Liotta bioprosthesis secondary to commissural tear associated with minimal calcifications that required a reoperation in emergency.
