Home sleep apnea testing in patients with continuous flow LVAD: is it feasible?

Study Objectives: The incidence of sleep-related breathing disorder (SRBD) remains unclear in patients with a continuous flow left ventricular assist device (LVAD). Polysomnography (PSG) remains the gold standard for diagnosis, but logistical challenges make home sleep apnea testing (HSAT) a more practical alternative. WatchPat has failed to accurately diagnose SRBD in this population.
