Abstract:
We describe a 36-year-old male with a HeartWare LVAD and a Medtronic Virtuoso DR pacemaker in whom increased intrathoracic impedance preceded suction events, low LVAD flows, symptoms of a heart failure exacerbation, and hospitalization. Measurement of intrathoracic impedance may identify fluid shifts prior to symptoms and predict adverse events in patients with an LVAD.
