Obstructive sleep apnea syndrome (OSAS) is a common, and often under-diagnosed, affecting 9% of men and 4% of women in the middle age. The prevalence of pulmonary hypertension in OSAS varies from 15 to 20%. It is generally moderate and due to intra-thoracic pressure variations and episodes of oxygen desaturations. We report the case of a patient in whom the obstructive sleep apnea syndrome, was resposible for a very important pre-capillary pulmonary hypertension and right ventricular systolic dysfunction (RV). We also report the marked improvement of this pulmonary hypertension (PH) and the recovery of a good function of the right ventricle under continuous positive pressure therapy. Rare are the authors who reported the occurrence of dysfunction of RV in the context of an OSAS, ethere rmains a need for serial evaluation of RV function in pulmonary hypertension during OSAS
