Abstract
Nocturnal periodic breathing (PB) is often observed in patients with c
ongestive heart failure (CHF). We investigated the sleep architecture
polysomnographically in a 54-year-old man with CHF due to mitral regur
gitation before and after surgical treatment. We found that the overni
ght frequency of central dominant sleep apnea decreased from 154 to 56
, and the lowest nocturnal oxygen saturation increased from 66% to 85%
postoperatively. These improvements in the manifestations of PB might
be attributed to the improved hemodynamics after successful valve rep
lacement.
