We present the case of a 59-year-old Caucasian man with a nonischemic cardiomyopathy who underwent implantation of HeartWare® (HeartWare Inc., Framingham, MA) ventricular assist devices (HVAD) for biventricular support due to refractory cardiogenic shock after attempted ventricular tachycardia ablation. After implantation of biventricular HVADs, he developed hypoxemia that failed to correct with administration of supplemental oxygen. A patent foramen ovale (PFO) was discovered on postoperative transesophageal echocardiogram (TEE). Speed adjustment of both the right and left HVADs under TEE guidance allowed for spontaneous closure of the PFO and resolution of the hypoxemia.Keywords: biventricular mechanical support; advanced heart failure; biventricular assist devices; HeartWare®; hypoxemia(Published: 18 October 2013)Citation: Mechanical Circulatory Support 2013, 4: 22638 - http://dx.doi.org/10.3402/mcs.v4i0.22638
