RT Journal Article T1 Severe hypoxaemia with a left ventricular assist device in a minipig model with an undiagnosed congenital cardiac disease A1 Quintana Villamandos, María Begoña A1 Rodríguez Bernal, Guillermo Juan A1 Pérez Caballero, Ramón A1 Otero, Javier A1 Ruiz Fernández, Manuel A1 Delgado Martos, María Jesús A1 Sánchez Hernández, José Javier A1 Delgado Baeza, Emilio A1 Cañizo López, Juan Francisco Del AB We describe the placement of a left ventricular assist device (LVAD) in a pig with spontaneously occurring atrial septal defect (ASD) (incidental finding) that created a right-left cardiac shunt, with subsequent severe hypoxaemia. Early diagnosis was critical in order to prevent end-organ damage due to hypoxaemia. Adequate monitoring alerted us to the deterioration in oxygenation, haemodynamics and cerebral oxygen metabolism. This forced us to change the level of assistance provided by the pump, and thus dramatically correct this impairment. Necropsy revealed an ostium secundum ASD. In conclusion, if hypoxaemia presents after implementation of an LVAD, the presence of a right-left shunt must be ruled out. The first step must be a judicious reduction in assist device flow to minimize intracardiac shunting. Subsequently, atrial septal closure of the defect should be considered. We report an experimental model of severe hypoxaemia after placement of an LVAD as part of a larger research project PB SAGE Publications SN 0023-6772 YR 2012 FD 2012-01-01 LK https://hdl.handle.net/20.500.14352/98036 UL https://hdl.handle.net/20.500.14352/98036 LA eng NO Quintana-Villamandos B, Rodríguez-Bernal GJ, Pérez-Caballero R, Otero J, Ruiz M, Delgado-Martos MJ, Sánchez-Hernández JJ, Delgado-Baeza E, Del Cañizo JF.
