Abstract Introduction Central sleep apnea is commonly seen in patients with heart failure. Here we present a case demonstrating shifting of predominant apneic events from central to obstructive type after placement of left ventricular assist device (LVAD) in end stage heart failure patient. Report of case(s) Case Presentation: 66 year-old African American male has past medical history of chronic congestive heart failure diabetes, hypertension, paroxysmal atrial fibrillation, anemia, hypothyroidism, chronic kidney disease and sleep apnea. Prior to his LVAD placement, his left ventricular ejection fraction (EF) was <10%. Patient was diagnosed with central sleep apnea with AHI of 58 (with 92% of apneic events being central events), oxygen nadir of 74%. Subsequently, patient had LVAD placed for symptomatic heart failure and repeat polysomnogram repeated at six month demonstrated an improved AHI of 45.8 with predominantly obstructive and mixed apneic events, with only 12.5% being central events. Conclusion This case report highlights not only the improvement of the sleep apnea in CHF treated with LVAD but also shows the shift of apneic events from predominantly central to obstructive type post LVAD.
