Left ventricular assist device (LVAD) implantation is an important treatment option for patients with advanced heart failure. The presence of a patent foramen ovale (PFO) may elicit undesired consequences in LVAD patients: hypoxemia and paradoxical embolization. The variable physiological status of the patient with heart failure can make pre-LVAD implant identification of a PFO elusive. When identified pre- or intraoperatively, PFO is closed at time of LVAD implantation. In the case of delayed diagnosis, percutaneous PFO closure has proven to be a feasible and safe solution. As mechanical circulatory support gains prevalence, it is important to raise awareness of physiological implications of right-to-left shunt during mechanical circulatory support. We reviewed the diagnostic and therapeutic management of PFO in LVAD patients.
